+# shockbot

-<br/>
+Self-hosted AI code review for Gitea, powered by Ollama. Tag `@shockbot` in a PR comment to trigger a review, or configure it to auto-review on every PR.

-> **🚀 Pullfrog is in beta!** We're onboarding users in waves. [Get on the waitlist →](https://pullfrog.com/join-waitlist)
+Based on [pullfrog](https://github.com/pullfrog/pullfrog) — simplified for self-hosted Gitea + Ollama setups.

-<br/>
+## Requirements

-## What is Pullfrog?
+- Gitea instance
+- Ollama instance reachable from your Gitea Actions runner
+- A Gitea bot account with repo read/write access

-Pullfrog is a GitHub bot that brings the full power of your favorite coding agents into GitHub. It's open source and powered by GitHub Actions.
+## Setup

- **Tag `@pullfrog`** — Tag `@pullfrog` in a comment anywhere in your repo. It will pull in any relevant context using the action's internal MCP server and perform the appropriate task.
- **Prompt from the web** — Trigger arbitrary tasks from the Pullfrog dashboard
- **Automated triggers** — Configure Pullfrog to trigger agent runs in response to specific events. Each of these triggers can be associated with custom prompt instructions. 
-  - issue created
-  - issue labeled
-  - PR created
-  - PR review created

+### 1. Create a bot account

-Pullfrog is the bridge between your preferred coding agents and GitHub. Use it for:
- 
- **🤖 Coding tasks** — Tell `@pullfrog` to implement something and it'll spin up a PR. If CI fails, it'll read the logs and attempt a fix automatically. It'll automatically address any PR reviews too.
- **🔍 PR review** — Coding agents are great at reviewing PRs. Using the "PR created" trigger, you can configure Pullfrog to auto-review new PRs.
- **🤙 Issue management** — Via the "issue created" trigger, Pullfrog can automatically respond to common questions, create implementation plans, and link to related issues/PRs. Or (if you're feeling lucky) you can prompt it to immediately attempt a PR addressing new issues.
- **Literally whatever** — Want to have the agent automatically add docs to all new PRs? Cut a new release with agent-written notes on every commit to `main`? Pullfrog lets you do it.
+Create a Gitea account for the bot (e.g. `shockbot`) and generate an access token with `read:issue`, `write:issue`, `read:pull_request`, `write:pull_request` scopes.

+### 2. Add secrets to your repo

-<!-- Features
- **Agent-agnostic** — Switch between agents with the click of a radio button.
- ** -->
+| Secret | Description |
+|--------|-------------|
+| `BOT_TOKEN` | Gitea access token for the bot account |
+| `OLLAMA_HOST` | URL of your Ollama instance (e.g. `http://192.168.1.10:11434`) |

-<!-- 
-## Get started
+### 3. Add the workflow

-Install the Pullfrog GitHub App on your personal or organization account. During installation you can choose to limit access to a specific repo or repos. After installation, you'll be redirected to the Pullfrog dashboard where you'll see an onboarding flow. This flow will create your `pullfrog.yml` workflow and prompt you to set up API keys. Once you finish those steps (2 minutes) you're ready to rock.

-
-<details>
-<summary><strong>Manual setup instructions</strong></summary>
-
-You can also use the `pullfrog/pullfrog` Action without a GitHub App installation. This is more time-consuming to set up, and it places limitations on the actions your Agent will be capable of performing.
-
-To manually set up the Pullfrog action, you need to set up two workflow files in your repository: `pullfrog.yml` (the execution logic) and `triggers.yml` (the event triggers).
-
-#### 1. Create `pullfrog.yml`
-
-Create a file at `.github/workflows/pullfrog.yml`. This is a reusable workflow that runs the Pullfrog action.
+Create `.gitea/workflows/shockbot.yml` in the repo you want reviewed:

 ```yaml
-# PULLFROG ACTION — DO NOT EDIT EXCEPT WHERE INDICATED
-name: Pullfrog
+name: Shockbot Review
 on:
-  workflow_dispatch:

+          GITEA_URL: https://git.shockvpn.com
+          GITEA_PR_NUMBER: ${{ github.event.issue.number }}
 ```

-#### 2. Create `triggers.yml`
+## Configuration

-Create a file at `.github/workflows/triggers.yml`. This workflow listens for GitHub events and calls the `pullfrog.yml` workflow with the event data.
+Three values need to be configured — the rest come from the event context (as shown in the workflow example above) or are set automatically by Gitea Actions.
+
+| Secret / env var | Description |
+|-----------------|-------------|
+| `BOT_TOKEN` | Gitea access token for the bot account |
+| `OLLAMA_HOST` | URL of your Ollama instance |
+| `GITEA_URL` | URL of your Gitea instance |
+
+### Model
+
+Defaults to `qwen3.6:35b`. Override with the `model` input:

 ```yaml
-name: Agent Triggers
-
-on:
-  issue_comment:
-    types: [created]
-  pull_request_review_comment:
-    types: [created]
-  issues:
-    types: [opened, assigned]
-  pull_request_review:
-    types: [submitted]
-  # add other triggers as needed
-  
-
-jobs:
-  pullfrog:
-    
-    # trigger conditions (e.g. only run if @pullfrog is mentioned)
-    if: contains(github.event.comment.body, '@pullfrog') || contains(github.event.issue.body, '@pullfrog')
-    
-    permissions:
-      id-token: write
-      contents: write
-      issues: write
-      pull-requests: write
-      actions: read
-      checks: read
-    uses: ./.github/workflows/pullfrog.yml
-    with:
-      # pass the full event payload as the prompt
-      prompt: ${{ toJSON(github.event) }}
-    secrets: inherit
+with:
+  prompt: "Review this pull request"
+  model: "llama3.1:70b"
 ```

-</details>
-->
+## Usage
+
+- **Auto-review on PR open** — the PR trigger fires automatically on new PRs
+- **Manual trigger** — comment `@shockbot review` on any PR to trigger a review on demand
+- **Custom prompt** — any comment mentioning `@shockbot` is passed as the prompt, so `@shockbot review focusing on security` works

-# `pullfrog/get-installation-token`
-
-Get a GitHub App installation token in a workflow job. This convenience action makes it easier to integrate Pullfrog into existing CI workflows.
-
-This action:
-
- Provides a GitHub App installation token for later workflow steps.
- Works for the current repository out of the box.
- Can optionally include additional repositories.
- Masks the token in logs.
- Revokes the token automatically in the post step.
-
-## Requirements
-
- Workflow or job permissions must include `id-token: write`.
- The Pullfrog GitHub App must be installed on the target repositories.
- If you pass `repos`, each repository must be installed for the same app installation.
-
-## Inputs
-
-| Name | Required | Description |
-| --- | --- | --- |
-| `repos` | no | Comma-separated additional repo names to include, for example: `repo1,repo2`. The current repo is always included. |
-
-## Outputs
-
-| Name | Description |
-| --- | --- |
-| `token` | GitHub App installation token |
-
-## Usage
-
-### Basic (current repo only)
-
-```yaml
-permissions:
-  id-token: write
-  contents: read
-
-jobs:
-  example:
-    runs-on: ubuntu-latest
-    steps:
-      - uses: actions/checkout@v4
-
-      - name: Get installation token
-        id: token
-        uses: ./action/get-installation-token
-
-      - name: Call GitHub API with token
-        run: gh api repos/${{ github.repository }}
-        env:
-          GH_TOKEN: ${{ steps.token.outputs.token }}
-```
-
-### Include extra repositories
-
-```yaml
-permissions:
-  id-token: write
-  contents: read
-
-jobs:
-  example:
-    runs-on: ubuntu-latest
-    steps:
-      - name: Get token for current repo plus extra repos
-        id: token
-        uses: ./action/get-installation-token
-        with:
-          repos: pullfrog,app
-
-      - name: Checkout another repo with installation token
-        uses: actions/checkout@v4
-        with:
-          repository: pullfrog/pullfrog
-          token: ${{ steps.token.outputs.token }}
-          path: action-repo
-```
-
-## Notes
-
- `repos` expects repository names, not `owner/repo`.
- Token lifetime is managed by GitHub, but this action also revokes the token during post-run cleanup.
- Prefer step output usage (`${{ steps.<id>.outputs.token }}`) rather than writing tokens to files.
-
-## Troubleshooting
-
- `Error: id-token permission is required`:
-  Add `id-token: write` in workflow or job permissions.
- Token works for current repo but not an extra repo:
-  Ensure that repository is listed in `repos` and the app installation has access to it.

-  Build: `### Checklist
-
-1. **plan phase** (optional, for complex tasks): delegate a subagent to analyze the requirements, read AGENTS.md and relevant code, and produce a step-by-step implementation plan. Include \`${ghPullfrogMcpName}/set_output\` with the plan so it returns to you. Use mini or auto effort. You can also use \`ask_question\` for codebase questions/investigations.
-
-2. **setup** (your responsibility as orchestrator): before the build phase, checkout or create the branch:
-   - **PR event, modifying the existing PR**: call \`${ghPullfrogMcpName}/checkout_pr\`
-   - **new branch**: use \`${ghPullfrogMcpName}/git\` to create a branch (\`git checkout -b pullfrog/branch-name\`)
-   Subagents have no git/checkout tools — the working tree must be ready before delegation.
-
-3. **build phase**: delegate a subagent with the implementation task. Include in its prompt:
-   - the plan (if you ran a plan phase)
-   - specific files to modify and why
-   - instruct the subagent to plan its approach before writing code: identify which files need to change, key design decisions, and edge cases. for non-trivial changes, consider whether there's a more elegant approach before committing to implementation.
-   - testing expectations: run relevant tests/lints before committing
-   - pre-commit quality check: instruct the subagent to review its own diff before committing — verify only intended changes are present, no debug artifacts or commented-out code remain, and no unrelated files were modified. the change should be clean enough that a senior engineer would approve it without hesitation. for non-trivial changes, ask whether there's a simpler way to achieve the same result.
-   - commit locally via shell (\`git add . && git commit -m "..."\`)
-   - call \`${ghPullfrogMcpName}/set_output\` with a concise summary including the branch name (this is how results get back to you)
-
-4. **review phase** (optional, for non-trivial changes): before pushing, delegate a review subagent to check the pending diff. Use \`ask_question\` for quick spot-checks, or delegate a full Review subagent for high-stakes changes. This catches issues before they're public.
-
-5. **finalize** (your responsibility as orchestrator): after the build (and optional review) completes:
-   - push the branch via \`${ghPullfrogMcpName}/push_branch\`
-   - create a PR via \`${ghPullfrogMcpName}/create_pull_request\`
-   - call \`${ghPullfrogMcpName}/report_progress\` with the final summary including PR link
-
-### Notes
-
-For simple, well-defined tasks, a single build subagent is sufficient — skip the plan and review phases.
-
-Your subagent receives ONLY what you write. Include file paths, constraints, conventions, and any context from AGENTS.md or the codebase directly in the prompt. Subagents have file ops, shell, and read-only GitHub tools — but NO git/checkout, dependency, GitHub-write, or remote-mutating tools.`,
-
-  AddressReviews: `### Checklist
-
-1. Before delegating, checkout the PR branch yourself via \`${ghPullfrogMcpName}/checkout_pr\` — subagents have no git/checkout tools.
-
-2. Include in its prompt:
- instruct it to fetch review comments via \`${ghPullfrogMcpName}/get_review_comments\` (subagents have read-only GitHub tools)
- for each comment: understand the feedback, make the code change, and record what was done
- test changes, then review the diff before committing — verify only intended changes are present, no debug artifacts remain, and the changes are clean enough that a senior engineer would approve without hesitation
- commit locally via shell (\`git add . && git commit -m "..."\`)
- call \`${ghPullfrogMcpName}/set_output\` with a JSON object: \`{ "summary": "...", "replies": [{ "comment_id": 123, "thread_id": "...", "reply": "Fixed by ..." }, ...] }\` — this is how results get back to you
-
-3. After the subagent completes:
- push changes via \`${ghPullfrogMcpName}/push_branch\`
- reply to each comment using \`${ghPullfrogMcpName}/reply_to_review_comment\` with the subagent's suggested replies
- resolve addressed threads via \`${ghPullfrogMcpName}/resolve_review_thread\`
- call \`${ghPullfrogMcpName}/report_progress\` with a brief summary
-
-### Effort
-
-Use auto or max effort depending on review complexity.`,
-
-  Review: `### Checklist
-
-1. Checkout the PR via \`${ghPullfrogMcpName}/checkout_pr\` — this returns PR metadata and a \`diffPath\`. Read the diff to identify the major areas of change.
-2. Delegate multiple subagents in a single \`${ghPullfrogMcpName}/delegate\` call, each focused on a specific area. For example, a PR touching action/, components/, and prisma/ might get three subagents: "action-review", "frontend-review", "schema-review".
-3. After all subagents return, consolidate their findings into a single review.

-
-Each task in the \`tasks\` array should include:
- the diff file path so the subagent can read it
- what specific area/aspect to focus on (e.g., "review the database migration and schema changes in prisma/")
- instruct it to read the diff, trace data flow, check boundaries, and verify assumptions within its area. subagents have read-only GitHub tools (\`${ghPullfrogMcpName}/get_pull_request\`, etc.) for fetching additional context.
- instruct it to plan its investigation before diving in: identify the highest-risk areas (tricky state transitions, boundary crossings, assumption chains) and prioritize depth over breadth
- draft inline comments with NEW line numbers from the diff — every comment must be actionable (2-3 sentences max)
- after drafting, instruct it to critique its own comments: drop any that are praise, style preferences, speculative/unverified claims, about pre-existing code unrelated to the PR, or not actionable
- use GitHub permalink format for code references
- call \`${ghPullfrogMcpName}/set_output\` with a JSON object: \`{ "summary": "...", "comments": [{ "path": "file.ts", "line": 42, "body": "..." }, ...] }\` — this is how findings get back to you
-
-### Post-delegation
-
-After all tasks complete, consolidate into a **single** review:
- merge the \`comments\` arrays from all subagent outputs
- submit one \`${ghPullfrogMcpName}/create_pull_request_review\` with the merged comments and a unified summary body
- call \`${ghPullfrogMcpName}/report_progress\` with the summary
- if no subagent found actionable issues, skip the review — just call \`report_progress\` noting the PR was reviewed
-
-Use max effort for thorough reviews.`,
-
-  Plan: `### Checklist
-
-1. Include in its prompt:
-   - the task to plan for
-   - relevant codebase context (file paths, architecture notes from AGENTS.md)
-   - instruct it to produce a structured, actionable plan with clear milestones
-   - call \`${ghPullfrogMcpName}/set_output\` with the plan (this is how results get back to you — you'll need the plan to craft the next subagent's prompt)
-2. After the subagent completes, call \`${ghPullfrogMcpName}/report_progress\` with the plan.
-
-### Effort
-
-Use mini or auto effort. After receiving the plan, you may delegate a Build subagent to implement it.`,
-
-  Fix: `### Checklist
-
-1. Before delegating, checkout the PR branch yourself via \`${ghPullfrogMcpName}/checkout_pr\` — subagents have no git/checkout tools.
-
-2. Delegate a single fix subagent with:
- the check_suite_id to fetch logs via \`${ghPullfrogMcpName}/get_check_suite_logs\` (subagents have read-only GitHub tools)
- the PR diff file path (from checkout_pr result) so it can understand what the PR changed
- CRITICAL: instruct it to verify the failure was INTRODUCED BY THIS PR before fixing. If unrelated, abort and report.
- instruct it to read the workflow file, reproduce locally with the EXACT same commands CI runs
- fix the issue, then verify the fix by re-running the exact CI command
- pre-commit quality check: review the diff before committing — verify only the fix is present, no debug artifacts, no unrelated changes. the fix should be clean enough that a senior engineer would approve it without hesitation.
- commit locally via shell (\`git add . && git commit -m "..."\`)
- call \`${ghPullfrogMcpName}/set_output\` with a concise summary: what failed, why, and the fix applied (this is how results get back to you)
-
-3. After the subagent completes:
- push changes via \`${ghPullfrogMcpName}/push_branch\`
- call \`${ghPullfrogMcpName}/report_progress\` with the diagnosis and fix summary
-
-### Effort
-
-Use auto effort.`,
-
-  Task: `### Checklist
-
-1. Handle this general-purpose task. For simple operations (labeling, commenting, answering questions, running a single command), you can often handle it directly without delegation.
-2. When the task involves **substantial work** — code changes across multiple files, multi-step investigations, or tasks that benefit from focused context — use \`delegate\` and \`ask_question\` liberally:
-   - \`ask_question\`: quick codebase research, finding files, understanding architecture. Use freely — multiple calls in sequence is fine.
-   - \`delegate\`: research, local coding tasks, and codebase investigations. Each subagent gets dedicated context, so break complex work into focused subtasks and delegate each one. For independent subtasks, batch them in a single \`${ghPullfrogMcpName}/delegate\` call to run in parallel.
-3. Include in each task's prompt:
-   - the full subtask description with all relevant context
-   - exactly what information to return. the subagent's output is your only way to get results back — be precise about what you need.
-   - if code changes are needed: branch naming, testing, commit instructions (do NOT instruct to push or create PR)
-   - if code changes are needed: instruct it to review its own diff before committing — verify only intended changes are present, no debug artifacts remain, and the changes are clean enough that a senior engineer would approve without hesitation
-4. Post-delegation:
-   - call \`${ghPullfrogMcpName}/report_progress\` with results
-   - if the task involved code changes, push via \`${ghPullfrogMcpName}/push_branch\` and create a PR via \`${ghPullfrogMcpName}/create_pull_request\`
-   - if the task involved labeling, commenting, or other GitHub operations, perform those directly
-5. Use mini effort for simple research tasks, auto for typical tasks, max for complex multi-file changes.`,

+Inline-vs-body split: concerns that anchor to a specific line go inline (use the \`comments\` parameter). Body \`### \` sections are reserved for concerns that **have no line to anchor to** — typically because the concern is about *absence* (something the diff should have done but didn't), *sequencing* (rollout / deletion / migration order), *design decisions only the human can make*, or *scope questions the diff implicitly raises but doesn't address*. A concern that anchors to a line but has broad implications still goes inline (use the technical-details block there to capture the implications — see Inline technical details below). If you found no non-anchorable concerns, the body has zero \`### \` issue sections — just the preamble + metadata.

+\`\`\`
+**Reviewed changes** — one sentence on what was reviewed in this run. For Review (initial), this is what the PR does and why. For IncrementalReview, this is what changed since the prior shockbot review. Focus on intent, not mechanics.
+
+- **Short human-readable title** — 1 sentence per substantive change. Write a short prose phrase; when you name a file, type, or function, put that name in backticks (e.g. **Add \\\`TodoTracker\\\` for live checklists**). A reviewer should understand the full reviewed scope from this list alone — this IS the dispassionate "what was reviewed and what changed" overview, so cover the substantive changes, not just the loudest ones.
+
+**IMPORTANT**: these bullets describe what the PR *changed* — they are a neutral inventory of changes, not reviewer findings. "Added X feature" or "Refactored Y service" is correct. "X feature has a race condition" or "Y service is missing validation" is a FINDING — it goes in an inline comment or a \`### \` section, never in the preamble bullets.

+
+## 2. Cross-cutting issue sections (zero or more)
+
+For each cross-cutting concern, one \`### \` section. Use this exact shape:
+
+\`\`\`
+### {emoji} {short, descriptive title — what's wrong, not what to do}
+
+{Human-readable problem write-up. Describes the PROBLEM only — what's broken, what the symptom is, what the blast radius is. NO asks, NO suggested fixes, NO "the right thing to do is...". Asks and fixes live in the technical-details block below; the visible part is for the human to *understand* the problem, not to implement it.}
+
+<details><summary>Technical details</summary>
+
+**Affected sites:**
+- {file path:line} — {what's wrong there}
+
+**Required outcome:**
+- {what the fix needs to achieve, not how to achieve it}
+
+**Suggested approach** (optional): {sketch one or more reasonable directions when the fix shape is non-obvious}
+
+**Open questions for the human** (optional): {decisions an implementing agent shouldn't make unilaterally}
+
+</details>
+\`\`\`
+
+Concrete example of the visible part of a non-anchored section (technical-details block unchanged from the template above):
+
+\`\`\`
+### ℹ️ Legacy \`opencode.ts\` has no documented deletion plan
+
+The v2 harness lands alongside the v1 file and imports one helper from it. Worth a follow-up issue or a TODO so the next maintainer doesn't have to re-derive the cleanup plan.
+\`\`\`
+
+The example's value is its *shape*: a finding about absence (no deletion plan), not a line-anchored bug. Body sections live or die on whether the concern genuinely doesn't fit on a line.
+
+**Heading severity emoji** — every \`### \` heading carries one:
+
+- 🚨 critical — blocks merge (data loss, security, broken core flow)
+- ⚠️ important — must address before merging (regression, missing validation, incorrect behavior)
+- ℹ️ informational — surfaced for awareness; mergeable as-is
+
+**Visible problem write-up rules:**
+
+- **No asks, no suggested fixes** in the visible part. The visible portion describes the problem; the technical-details block describes the fix shape and any open questions. The exception: a fix so self-evident that NOT stating it would be weird (e.g. "the typo is missing an 'r'") — in that case, fold it into the problem statement and skip the suggested-approach block in technical details too.
+- **Never two successive plain paragraphs.** Every transition between block-level elements must alternate prose with structure: paragraph → bullet list → paragraph; paragraph → code fence → bullet list; paragraph → table → paragraph. Two consecutive paragraphs in a row create a wall of text that's impossible to digest. If you catch yourself writing one, find a way to split it: pull a list out of it, drop a 2-3 line code fence between them, or merge them into a single tighter paragraph.
+- **Per-paragraph budget:** ~3 sentences max. Past that, you're explaining where you should be structuring.
+- **Identifier discipline still applies** in the visible part. Lead with behavior in plain English; name an identifier only when it's the subject of the concern or a public surface a reader would recognize. The technical-details block is where dense identifier references belong.
+
+**Technical-details block rules:**
+
+- Written as plain markdown bold-header sections directly inside \`<details>\` — no code fence wrapper. Use \`**Affected sites:**\`, \`**Required outcome:**\`, and optionally \`**Suggested approach:**\` and \`**Open questions for the human:**\`. Skip optional sections when they add nothing.
+- File paths and \`file:line\` refs are encouraged — the next agent uses these to navigate. Identifier density is fine here.
+- Slightly more verbose than the absolute minimum is OK when it materially helps the next agent: a small code snippet (3-backtick fence), a short table of mismatched values, a one-paragraph "why CI doesn't catch it" note. Skip massive scaffolding — the implementing agent writes that.
+- The contents are agent-readable — a fix-agent will pull the body down and use this block as the brief.
+
+## Inline technical details
+
+Inline comments are short (~2-3 sentences) by default. When an inline finding has broader implications worth recording for a fix-agent — e.g. a localized bug whose proper fix requires touching several files, or where the right fix depends on a design decision the human needs to make — append a collapsed \`<details><summary>Technical details</summary>\` block to the inline comment's body. Same plain-markdown bold-header shape as the body-section technical-details block (\`**Affected sites:**\` / \`**Required outcome:**\` / optional \`**Suggested approach:**\` / optional \`**Open questions for the human:**\`).
+
+The visible part of the inline comment stays scannable; the depth is one click away for any agent that needs it.
+
+## 3. \`### ℹ️ Nitpicks\` (optional, last section)
+
+Only when there are nits that for some reason can't be inlined. Filepaths in nit text are fine — these are simple enough that a human or agent reads once and acts. No technical-details block.
+
+\`\`\`
+### ℹ️ Nitpicks
+
+- {nit, with file path inline if useful, ≤ ~200 chars}
+- ...
+\`\`\`
+
+## Inline comment shape
+
+Inline comments are plain, no-frills anchors on the affected line:
+
+- **No emojis.** Do not prefix the visible text with 🚨 / ⚠️ / ℹ️ or any other emoji. The severity is already communicated by the technical-details block.
+- **Lead with a 1-2 sentence problem statement.** The reader is looking at the line in question, so don't restate what the line says — describe what's wrong with it.
+- **Optional \`<details><summary>Technical details</summary>...</details>\` collapsible** for findings whose technical context (longer file:line references, related-code snippets, suggested approach, regression-risk notes) would overwhelm the human-readable lead-in. Same plain-markdown bold-header shape as the body technical-details block — see *Inline technical details* above. Encouraged whenever the depth helps a downstream fix-agent; don't force one when the inline lead-in already says everything.
+- **Visible portion ≤ 2-3 sentences.** If you find yourself writing more, that's the cue to split the depth into the \`Technical details\` collapsible.
+- **Multi-site findings go inline too, as ONE comment.** A finding that spans multiple files or multiple lines is still a single inline comment — anchor it to the PRIMARY causal site (the place a developer would fix first), and list the other affected sites in the \`**Affected sites:**\` section of the technical-details block. "Spans multiple files" is NOT a reason to put a finding in the body. **Never post two separate inline comments for the same logical issue** — one finding = one comment, always. If the same root cause (e.g. the same lock key used in two methods, the same missing check in two places) shows up in two locations, pick the most important location and list the other in \`**Affected sites:**\`.
+- **No non-actionable comments.** Do not post inline comments that conclude "this is fine" or "this is acceptable" or "worth noting but OK". If something is not a finding, don't post it. Every inline comment must identify a problem the author should address.
+- **Anchor to the exact problem line.** Use the \`| newLine |\` column to find the specific line where the problematic symbol is **defined or first assigned** — not a nearby related line. If the symbol is \`isAnyPending\`, anchor to the line that defines \`isAnyPending\`, not a line that uses a different variable nearby.
+
+## Body-wide rules
+
+- **Inline-vs-body discipline (repeated for emphasis):** anything that anchors to a specific line goes inline (with a \`<details>Technical details</details>\` block when the implications are broad). The body is for non-anchorable concerns only — absence, sequencing, design decisions, scope questions, architectural risk.
+- **No \`### Issues found\` heading** above the issue sections — each \`### \` heading IS the issue.
+- **Severity emoji on every \`### \` heading** (🚨 / ⚠️ / ℹ️). No emoji on the preamble lead-in or on inline comments — only body \`### \` headings carry emojis.
+- **GitHub block-level rendering**: GitHub's markdown parser requires a blank line between ALL block-level elements (HTML tags like \`<br/>\`, \`<sub>\`, \`<details>\`, \`<b>\` and markdown syntax like headings, lists, blockquotes, code fences, paragraphs). Without a blank line, GitHub treats following content as a continuation of the HTML block and renders markdown syntax as literal text. ALWAYS separate block-level elements with a blank line.
+- **Backtick-wrap** every variable, identifier, or file name when you mention one (in either visible or technical-details portions).
+- **Don't repeat diff content**, don't include raw \`+123 / -45\` stats, don't include a changelog section, don't use horizontal rules (\`---\`).
+- **Pull file/commit counts from \`checkout_pr\` metadata** — never count manually.
+- **Legacy headings REMOVED.** Do not use \`### Key changes\`, \`### Issues found\`, \`<b>TL;DR</b>\`, or \`<sub><b>Summary</b>\`. The new structure subsumes them.`;

-1. **CHECKOUT** - Determine whether to checkout the existing PR branch or create a new one:
-   - **PR event, modifying the existing PR**: Call \`${ghPullfrogMcpName}/checkout_pr\` with the PR number to checkout the PR branch.
-   - **PR event, but user wants a NEW branch/PR**: Create a new branch with \`git checkout -b pullfrog/branch-name\` via the \`${ghPullfrogMcpName}/git\` tool.
+1. **task list**: create your task list for this run as your first action.

-   Branch names must be prefixed with "pullfrog/" and be specific enough to avoid collisions. Never commit directly to main/master/production.
+2. **plan** (optional, for complex tasks): analyze requirements, read AGENTS.md and relevant code, produce a step-by-step implementation plan.

-2. **DEPENDENCIES** - ${dependencyInstallationStep}
+3. **setup**: checkout or create the branch:
+   - **PR event, modifying the existing PR**: call \`${t("checkout_pr")}\`
+   - **new branch**: use \`${t("git")}\` to create a branch (\`git checkout -b shockbot/branch-name\`)

-3. **CONTEXT** - If the request requires understanding the codebase structure or conventions, gather relevant context. Read AGENTS.md if it exists. Skip this step if the prompt is trivial and self-contained.
+4. **build**: implement changes using your native file and shell tools:
+   - follow the plan (if you ran a plan phase)
+   - plan your approach before writing code: identify which files need to change, key design decisions, and edge cases. for non-trivial changes, consider whether there's a more elegant approach.
+   - run relevant tests/lints before committing

-4. **REQUIREMENTS** - Understand the requirements and any existing plan.
+5. **self-review**: judgment call — does YOUR diff warrant a fresh-eyes pass?

-5. **IMPLEMENT** - Make the necessary code changes using file operations. You should change the minimum amount of code necessary to accomplish your task. Emphasize code quality and elegance.
+   Skip self-review (commit directly) when the diff is **genuinely trivial**:
+   - doc typos, comment-only edits, whitespace/format-only, import reordering
+   - lockfile or generated-code regeneration, mechanical rename whose only effect is import-path updates (size of diff is irrelevant — read the *shape*, not the line count)
+   - low-risk dep patch bump from a trusted source

-6. **TEST** - Test your changes to ensure they work correctly. Run relevant tests, builds, or linters BEFORE committing. If tests fail, fix the issues and repeat this step until everything passes.
+   Run self-review when the diff has **any behavioral surface, however small**:
+   - 1-line changes to SQL operators / comparison logic / regexes / redirects / HTTP methods / response codes
+   - any change to money / tax / currency / billing / fee / refund / payout calculations or constants
+   - any change to auth / permissions / roles / sessions / tokens / signature verification
+   - any change to feature-flag defaults, retry counts, timeouts, rate limits, batch sizes
+   - new endpoints, new code paths, new error branches — even small ones
+   - mixed diffs (whitespace + a single semantic line) — the semantic line still triggers self-review
+   - anything you're uncertain about

-7. **COMMIT** - Commit your changes using \`${ghPullfrogMcpName}/git\` (e.g., \`git add .\` then \`git commit -m "message"\`), then push with \`${ghPullfrogMcpName}/push_branch\`. Do NOT use \`git push\` directly - it requires credentials that only the MCP tool provides.
+   Tie-breaker: when in doubt, run self-review. One false-positive subagent dispatch costs cents; one false-negative shipped bug costs much more. There's no value in dispatching for a typo, but there's also no excuse for skipping on a 1-line change to a billing path.

-8. **PROGRESS** - ${reportProgressInstruction}
+   Otherwise delegate the \`${REVIEWER_AGENT_NAME}\` subagent to review your diff with fresh eyes against YOUR TASK. The subagent's baked-in system prompt enforces a non-mutative + non-recursive contract: read-only file/search/web tools and read-only MCP queries only; no writes, shell side effects, state-changing MCP calls, or nested subagent dispatch. Enforcement is prose-only — restate the constraint in your dispatch instructions and do not relax it.

-9. **PR** - Determine whether to create a PR (if not already on a PR branch):
-   - **Default behavior**: Create a PR using ${ghPullfrogMcpName}/create_pull_request with an informative title and body. If you are working in the context of an issue (check EVENT DATA for \`issue_number\` where \`is_pr\` is not true), include "Closes #<issue_number>" in the PR body to auto-close the issue when merged.
-   - **Draft PR request**: If the user explicitly asks for a draft PR (e.g. "draft PR", "create as draft", "WIP"), create a PR with \`draft: true\`.
-   - **Branch-only request**: If the user explicitly asks for a branch without a PR (e.g. "don't create a PR", "branch only", "just create a branch"), do NOT create a PR. Simply push the branch and report the branch link.
+   Compose your \`${REVIEWER_AGENT_NAME}\` dispatch prompt using this template verbatim, substituting the \`<...>\` placeholders. The preamble aligns the orchestrator side of the dispatch contract with the reviewer's baked-in system prompt — both ends say the same thing about where the work lives and what to do on an empty diff.

-10. **FINAL REPORT** - Call report_progress one final time ONLY if you haven't already included all the important information (PR links, branch links, summary) in a previous report_progress call. If you already called report_progress with complete information including PR links after creating the PR, you do NOT need to call it again. Only make a final call if you need to add missing information. When making the final call, ensure it includes:
-   - A summary of what was accomplished
-   - Links to any artifacts created (PRs, branches, issues)
-   - If you created a PR, ALWAYS include the PR link. e.g.:
-     \`\`\`md
-     [View PR ➔](https://github.com/org/repo/pull/123)
-     \`\`\`
-   - If you created a branch without a PR, ALWAYS include a "Create PR" link and a link to the branch. e.g.:
-     \`\`\`md
-     [\`pullfrog/branch-name\`](https://github.com/pullfrog/scratch/tree/pullfrog/branch-name) • [Create PR ➔](https://github.com/pullfrog/scratch/compare/main...pullfrog/branch-name?quick_pull=1&title=<informative_title>&body=<informative_body>)

+   This is a PRE-COMMIT Build-mode self-review. The work to review lives in the working tree (uncommitted), NOT in committed history.

+   Branch: <branch> (off <base>)

+
+   Follow the template with the diff content (\`git diff origin/<base-branch>\`, single-rev form — \`main...HEAD\` and \`--cached\` both miss the uncommitted edits self-review runs on) and your task brief. Instruct the subagent to flag bugs, logic errors, missing edge cases, gaps between request and diff, and unintended changes.
+
+   Delegation + research discipline (distilled from \`/anneal\` canonical — these are codified learnings from many review rounds, not theoretical best practices):
+   - Do NOT summarize what you implemented — that biases the subagent toward validating the shape of your solution rather than questioning it.
+   - Do NOT curate a reading list of files. Let the subagent discover scope from the diff and codebase.
+   - Do NOT pre-shape output with a severity / category schema. That leaks your hypotheses; severity is your call during evaluation.
+   - Do NOT defect-hunt the diff yourself in parallel with the subagent. Your role is dispatch + evaluation; doing the review yourself reintroduces the implementation bias the subagent is meant to mitigate.
+   - For diffs that rely on third-party API contracts, SDK semantics, framework directives, or DB engine specifics, instruct the subagent to verify load-bearing claims via web search and quote source URLs rather than trust training data — this is the single most common review-quality failure mode.
+
+   Be **discerning** about what comes back. The reviewer is an AI subagent and is fallible — treat every finding as a hypothesis, not a directive, and **verify each one yourself** against the diff and the code before deciding whether to apply. You are searching for a solution that is **complete, minimal, and elegant** — you may need to think hard to find it. Do not over-engineer, do not be over-defensive, **do not write AI slop**. Reviewers bias toward *recommending additions*, and that bias has a recognizable slop texture: defensive checks for cases that cannot happen, extra logging, new abstractions used once, comments restating code, tests asserting tautologies, "just-in-case" guards, error handlers for cases the type system already rules out. Reject those. For each surviving finding, ask: would applying it leave the code more sound, correct, AND elegant? Two-out-of-three means look harder for a fix that gets all three before settling. After applying the fixes you accept, re-read your diff and be discerning about what *you just changed*: if any fix turned out to be bloat in context, revert it. Then verify only intended changes are present, no debug artifacts or commented-out code remain, no unrelated files were modified. Commit locally via shell (\`git add . && git commit -m "..."\`).
+
+6. **finalize**:
+   - confirm a clean working tree, then push via \`${t("push_branch")}\` (see *SYSTEM* Git rules if this fails — prepush errors are usually the repo's tests/lint, not infra timeouts)
+   - create a PR via \`${t("create_pull_request")}\`
+   - call \`${t("report_progress")}\` with the PR link or the exact error if push/PR failed

-2. **DEPENDENCIES** - ${dependencyInstallationStep}
+2. Checkout the PR branch via \`${t("checkout_pr")}\`.

-3. **FETCH COMMENTS** - Fetch review comments using ${ghPullfrogMcpName}/get_review_comments with \`pull_number\` and \`review_id\` from EVENT DATA. This returns \`commentsPath\` - read that file for full comment details with diff context. If EVENT DATA contains a \`triggerer\` field (indicating who requested fixes), you can pass \`approved_by\` to filter to only comments they approved with 👍.
+3. Fetch review comments via \`${t("get_review_comments")}\`.

-4. **UNDERSTAND** - Review the feedback provided. Understand each review comment and what changes are being requested.
+4. For each comment:
+   - understand the feedback
+   - **verify the finding yourself** against the actual code before deciding whether to apply — every comment (human or agent) is a hypothesis, not a directive. agent reviewers especially are fallible.
+   - you are searching for a solution that is **complete, minimal, and elegant** — you may need to think hard to find it. do not over-engineer, do not be over-defensive, **do not write AI slop**. reviewers bias toward *recommending additions*, and that bias has a recognizable slop texture: defensive checks for impossible cases, extra abstractions used once, comments restating obvious code, tests asserting tautologies, "just-in-case" guards, error handlers for cases the type system already rules out. reject those. evaluate whether applying the finding would leave the code more **sound, correct, AND elegant**; two-out-of-three is a signal to look harder for a fix that gets all three. if a request would add bloat — ceremony without commensurate correctness benefit — push back in your reply rather than mechanically applying it.
+   - if the request stands, make the code change using your native tools; otherwise reply explaining why
+   - record what was done (or why nothing was done)

-5. **CONTEXT** - If the request requires understanding the codebase structure or conventions, gather relevant context. Read AGENTS.md if it exists.
+5. Quality check:
+   - test changes, then review the diff before committing — verify only intended changes are present, no debug artifacts remain, no fix turned out to be bloat in context (revert any that did), and the changes are clean enough that a senior engineer would approve without hesitation
+   - commit locally via shell (\`git add . && git commit -m "..."\`)

-6. **IMPLEMENT** - Make the necessary code changes to address the feedback. Work through each review comment systematically.
-
-7. **REPLY** - Reply to EACH review comment individually. After fixing each comment, use ${ghPullfrogMcpName}/reply_to_review_comment to reply directly to that comment thread. Keep replies extremely brief (1 sentence max, e.g., "Fixed by renaming to X" or "Added null check"). If suggesting a small, specific, self-contained code change, use GitHub's suggestion format with \`\`\`suggestion blocks. After addressing a comment and posting your reply, use ${ghPullfrogMcpName}/resolve_review_thread with the thread_id to mark it as resolved. Only resolve threads where you made code changes to address the feedback — don't resolve threads that are already resolved, threads where no action was taken, or threads where you disagree with the feedback.
-
-8. **TEST** - Test your changes to ensure they work correctly. Run relevant tests, builds, or linters BEFORE committing. If tests fail, fix the issues and repeat until everything passes.
-
-9. **COMMIT** - Commit your changes with \`${ghPullfrogMcpName}/git\` (\`git add .\` then \`git commit -m "message"\`), then push with \`${ghPullfrogMcpName}/push_branch\`. The push will automatically go to the correct remote (including fork repos). Do not create a new branch or PR - you are updating an existing one.
-
-10. **PROGRESS** - ${reportProgressInstruction}

-Keep the progress comment extremely brief. The summary should be 1-2 sentences max (e.g., "Fixed 3 review comments and pushed changes."). Almost all detail belongs in the individual reply_to_review_comment calls, NOT in the progress comment.`,

+   - **if push fails**, call \`${t("report_progress")}\` with the exact error and STOP — do NOT reply or resolve any thread until the fix is live on the remote. Resolving a thread without the fix landing misleads the reviewer.
+   - **on push success**, for each thread you acted on:
+     - reply ONCE via \`${t("reply_to_review_comment")}\`. The \`comment_id\` parameter takes the root comment's numeric \`id=\` (from the first \`comment author=...\` tag in the \`${t("get_review_comments")}\` output) — NOT the \`thread=\` value; that's a separate GraphQL ID used by resolve. The runtime dedupes identical bodies within a session.
+     - **immediately** call \`${t("resolve_review_thread")}\` with that thread's \`thread=\` value as \`thread_id\`. Resolve every thread where you (a) made the requested code change in full — partial fixes leave the thread open — OR (b) replied with a substantive answer the user explicitly asked for. Do NOT resolve threads where you pushed back on the request and the disagreement is unresolved; leave those open for the human to mediate.

+      prompt: `### Checklist

-1. **CHECKOUT** - Call ${ghPullfrogMcpName}/checkout_pr with the PR number. This should give you all PR metadata you need, including a \`diffPath\`: a path to a temp file containing the PR diff.
+1. **task list**: create your task list for this run as your first action.

-2. **ANALYZE** - Read the modified files to understand the changes in context.
-   - **Understand the change**: What is being modified and why? What's the before/after behavior?
-   - **Evaluate the approach**: Is it sound? If not, focus on approach before implementation details.
+2. **checkout**: call \`${t("checkout_pr")}\` — this returns PR metadata and a \`diffPath\`. read the diff TOC end-to-end and treat its file line ranges as your coverage checklist.

-3. **INVESTIGATE** - Actively hunt for problems. Use these techniques:
-   - **Trace data flow**: Use grep to follow how data moves through the system. How is state passed? Where could it get lost?
-   - **Check boundaries**: What happens across process boundaries, module boundaries, async boundaries? State that exists in one context may not exist in another.
-   - **Explore failure modes**: What if this throws? What if that returns null? What if the network fails? What if this runs twice?
-   - **Verify assumptions**: If the code assumes X, verify X is actually true. Use grep, read related files, check documentation.
-   - **Consider lifecycle**: Initialization, cleanup, error recovery. Are resources acquired before use? Released after? What happens on cancellation?
-   - **Spot performance issues**: Nested loops over large collections, blocking I/O, memory leaks, excessive object creation in hot paths, inefficient array operations (e.g., repeated \`.find()\` in a loop).
-   - **Check PR consistency**: Does the PR title/description match the actual code changes? Flag significant discrepancies.
-   - Do NOT stop at "this looks reasonable." Dig until you either find a problem or have concrete evidence there isn't one.
+3. **triage**: orient yourself on the PR — identify *what kind of thing this is* (domain it touches, seams it crosses, external contracts it depends on, user-facing surfaces it changes). pull as much context as you need to render a confident, well-grounded review: read related files, grep for callers of changed symbols, check tests that exercise the touched paths, fetch related GitHub state. **you are the synthesizer** — never delegate understanding to subagents.

-4. **DRAFT LINE-BY-LINE COMMENTS** - Every comment must be actionable: the author should need to change something in response. 2-3 sentences max. Use the NEW line number from the diff (second column: \`| OLD | NEW | TYPE | CODE\`). If no issues found, skip to step 5. NO COMPLIMENTS. NO NITPICKING ABOUT CHANGES UNRELATED TO THE MAIN CHANGE. Non-actionable comments (praise, style preferences, minor optimizatfixons, documentation nits) must not be drafted. If no comments survive and you have no significant concerns, **do not submit a review**. Use \`${ghPullfrogMcpName}/report_progress\` to note the PR was reviewed and no issues were found.
+   if the PR is **genuinely trivial**, skip the fan-out entirely and submit a \`No new issues found.\` review per step 7.

-5. **WRITE SUMMARY** - Draft a 1-3 sentence summary for the review body. Include urgency level and any concerns about code outside the diff.
+   "Genuinely trivial" (skip):
+   - single-word doc typo, whitespace/format-only, comment-only across any number of files
+   - lockfile or generated-code regeneration (size of diff is irrelevant — read the *shape*)
+   - mechanical rename whose only effect is import-path updates
+   - low-risk dep patch bump

-6. **SUBMIT** — Use ${ghPullfrogMcpName}/create_pull_request_review:
-   - \`body\`: The summary from step 5
-   - \`comments\`: The inline comments from step 4
-   - \`approved\`: Set to \`true\` ONLY if the review contains no actionable feedback — neither inline comments nor actionable content in the body. An approval signals "no changes needed."
+   "Looks trivial but isn't" (do **NOT** skip — small diff, big blast radius):
+   - any 1-line change to SQL / regex / auth / billing / permission / signature-verification code
+   - flipping a feature-flag default, default config value, or retry/timeout constant
+   - changing a money/tax/currency/fee constant by any amount
+   - changing an HTTP method, redirect URL, response code, or status enum
+   - tightening or loosening a comparison operator (\`<\` ↔ \`<=\`, \`==\` ↔ \`!=\`)
+   - renaming a public API surface (still trivial in shape, but needs an impact lens)
+   - adding a new direct dependency (supply-chain surface)
+   - any "typo fix" in user-facing copy that changes meaning ("approved" → "denied")
+   - mixed diffs where a semantic 1-liner is buried in whitespace/formatting changes

-${permalinkTip}
-`,
+4. **lens decision — 0 or 2+, NEVER 1**.
+
+   The default is **0 lenses**: handle the review yourself end-to-end. Most PRs land here.
+
+   Dispatch **2+ \`${REVIEWER_AGENT_NAME}\` lenses in parallel** ONLY when ALL of the following are true:
+   - the PR is substantive (>5 files changed AND >200 net lines), OR touches a high-stakes subsystem (auth, billing, payments, schema migration, webhooks, secrets, RBAC, multi-tenant isolation, cron/scheduling)
+   - you can name 2+ distinct concrete failure modes that warrant independent lenses (one lens per failure mode; orthogonal, not overlapping)
+   - parallel-orchestrated independent perspectives meaningfully outperform what you'd find solo
+
+   **NEVER dispatch exactly one lens.** A single lens is just a more expensive version of doing the work yourself with a worse model — it adds wall time and a context-handoff for no orthogonality benefit. Either you have at least two genuinely independent failure-mode hypotheses (dispatch all in one turn), or you don't (do the review yourself).
+
+   When you do go multi-lens, lens framings come in two flavors:
+   - **themed lenses** — a perspective applied across the whole diff (correctness, security, user-journey, performance, etc.).
+   - **subsystem lenses** — a domain-scoped frame for high-stakes subsystems the PR touches (e.g. "the auth lens", "the billing lens", "the schema-migration lens"). **for high-stakes domains, lead with the subsystem lens rather than the generic themed equivalent** — "billing-subsystem" outperforms "correctness on billing code" because the framing primes the subagent to remember domain-specific failure modes (double-charges, refund races, currency rounding, dispute flows) the generic lens misses.
+
+   starter menu (combine, omit, or invent your own):
+   - **correctness & invariants** — bugs, races, error handling, edge cases, state-machine boundaries
+   - **impact** — stale references in code/tests/docs/configs/UI after rename/remove
+   - **research-validated assumptions** — third-party API contracts, SDK semantics, framework directives, version-gated behavior. **only pick when the PR's correctness depends on the contract behaving a specific way** — not when the API is merely used. The bar is "if the third-party contract differs from what the diff assumes, the PR is incorrect." When dispatched, the subagent must verify load-bearing claims via web search and quote source URLs.
+   - **security** — new endpoints, authZ, input validation, secrets handling, replay/CSRF/injection, cross-tenant isolation
+   - **user-journey** — UX-touching flows: walk through happy path and failure modes as a user
+   - **operational readiness** — observability, alerting, migrations (forward + rollback), feature flags, on-call burden
+   - **integration & cross-cutting** — API contracts between modules, backward-compat of public surfaces, multi-service ordering
+   - **test integrity** — meaningful coverage for the changed behavior; deterministic; no shared-state pollution
+   - **performance** — N+1 queries, hot-path allocation, latency budgets, index coverage
+   - **holistic** — does the PR make sense as a whole? symmetric flows (delete for every create, rollback for every migration)?
+   - **subsystem lenses** (invent as the PR demands) — auth, billing, payments, schema migration, webhooks, secrets, RBAC, multi-tenant isolation, cron/scheduling, etc.
+
+   The only subagent type is \`${REVIEWER_AGENT_NAME}\` — used for lens judgment work ("is this safe / correct / well-tested?"), runs on a mid-tier model.
+
+5. **fan out (only if step 4 said 2+ lenses)**: dispatch every \`${REVIEWER_AGENT_NAME}\` subagent for this run **IN A SINGLE ASSISTANT TURN, AS MULTIPLE PARALLEL TASK TOOL_USE BLOCKS IN ONE MESSAGE.**
+
+   ⚠️  CRITICAL — PARALLELISM IS THE ONLY REASON LENSES EXIST. ⚠️
+   The default tool-call behavior of Claude Code (and most agent runtimes) is **serial dispatch**: emit one Task call, await result, emit next, await, etc. This collapses your fan-out into a sequential review where each lens adds N × (orchestrator-think-time + lens-execution-time) to wall time. **YOU MUST OVERRIDE THIS DEFAULT.** Emit ALL of your Task tool_use blocks in the SAME assistant message, BEFORE you read ANY result from ANY of them. If you find yourself emitting one Task call, then thinking about the result, then emitting another — STOP and re-issue them all together. The whole point of going multi-lens is the wall-clock speedup from parallel execution; serial dispatch defeats it entirely.
+
+   ✅ Right pattern: one assistant turn with N Task tool_use blocks → wait → N results arrive together → aggregate.
+   ❌ Wrong pattern: turn 1 = Task(lens A) → turn 2 (after A's result) = Task(lens B) → turn 3 (after B's result) = Task(lens C). This is the failure mode. Do not do this.
+
+   You can also include your own \`read\` / \`grep\` / \`webfetch\` calls in the SAME turn as the parallel \`${REVIEWER_AGENT_NAME}\` dispatches — concurrent context-pulling on the orchestrator side runs in parallel with the lens fan-out and costs zero extra wall time.
+
+   if a subagent errors out, times out, or returns nothing usable, retry once with the same lens; if it still fails, proceed with partial coverage and note the missing lens in the review body — do not skip the fan-out entirely on a single subagent failure. each subagent gets:
+   - the diff path / target — reading the diff and the codebase is its job
+   - **only one lens** — never a multi-section "review for X, Y, and Z" prompt
+   - **a Task \`description\` set to the lens name** (e.g. \`"security"\`, \`"correctness"\`, \`"billing-subsystem"\`) — the harness reads this field to label the subagent's log lines so parallel runs can be told apart in CI output. without it, every subagent shows up as \`subagent#N\`.
+   - if the lens touches external contracts, instruct the subagent to verify load-bearing claims via web search rather than trust training data, and to quote source URLs in its reasoning. action runs are non-interactive — there's no human in the loop to catch "I'm pretty sure Stripe does X."
+   - ask the subagent to report findings with file paths and NEW line numbers from the diff so you can anchor inline comments without re-reading the entire diff.
+
+   delegation discipline:
+   - do NOT summarize the PR for them (biases toward a validation frame)
+   - do NOT hand them a curated reading list (let them discover scope)
+   - do NOT pre-shape their output with a finding schema
+   - do NOT mention the other lenses (independence is the point — overlapping findings are a strong signal)
+
+6. **aggregate & draft**: when the fan-out lands, merge findings; de-dup overlaps (two lenses catching the same issue = higher-confidence signal); trace each finding yourself before accepting it. drop praise, style preferences, speculative/unverified claims, findings about pre-existing code unrelated to the PR (heuristic: if the finding's root cause lives in lines this PR added or modified, it's in scope; otherwise drop unless the PR plausibly introduced or amplified the regression), and anything not actionable. also drop **bloat-shaped findings** — proposed fixes that would add defensive checks for cases that can't happen, abstractions used once, comments restating obvious code, tests asserting tautologies, or "just-in-case" guards. subagents are fallible and bias toward recommending changes; the bar for an actionable inline comment is sound + correct + elegant. recommending a change that improves only one of the three (or worse, degrades elegance to nominally improve correctness) makes the codebase worse, not better.
+
+   **Hunt for non-anchored concerns before drafting.** After collecting your anchored findings, deliberately scan for concerns that have no specific line to point at — typically: deletion / cleanup plans for code the diff replaces or shadows; rollout sequencing (what happens to in-flight state during deploy / revert?); coverage gaps the diff implies but doesn't add; scope questions that only the human can answer (e.g. is the legacy path going away or is this a long-term dual track?); architectural risks the diff opens up that aren't a single-line bug. On substantial PRs (migrations, refactors, multi-file rewrites, version bumps that change runtime semantics), at least one such concern almost always exists; if you can't think of any, your bar is probably too high.
+
+   for surviving findings that anchor to a specific file and line: **ALWAYS use inline comments** (pass via the \`comments\` parameter). NEVER put a line-anchored finding in the body as a \`### \` section — that is the wrong output format and wastes the reviewer's time. Every actionable concern that has a specific line to point at MUST be an inline comment.
+
+   for surviving findings with NO specific line anchor (absence of code, sequencing/rollout risk, design decisions): use body \`### \` sections.
+
+   inline comments — every comment must be actionable, 2-3 sentences max in the visible part. attach a \`<details>Technical details</details>\` block to any inline comment whose fix is non-trivial or has cross-file implications (see Inline technical details in the format below).
+
+   **Inline comment anchoring** (critical — get this wrong and all comments are silently dropped):
+   - \`path\`: the source file path from the \`diff --git a/<path> b/<path>\` header in the diff (e.g. \`apps/foo/bar.ts\`). This is NEVER the diffPath temp file — that path is only for \`read_file\` calls.
+   - \`line\`: the value in the \`| newLine |\` column of the formatted diff for the target line (RIGHT side, for added/context lines), or \`| oldLine |\` for LEFT side (removed lines). These are actual file line numbers, NOT the TOC position numbers.
+
+   for impact-analysis findings (stale references after rename/remove), report them in the review body ordered by severity (runtime breakage > incorrect docs > stale comments) rather than as inline comments unless they're anchored to a specific line.
+
+7. **submit**: ALWAYS submit exactly one review via \`${t("create_pull_request_review")}\`. **Do NOT call \`report_progress\`** — it creates a second visible comment and must not be used in Review mode. The review IS the final record; the progress comment is cleaned up automatically.
+
+   **MANDATORY pre-submission self-check**: before calling \`${t("create_pull_request_review")}\`, do both of these:
+   1. For each finding already in your \`comments\` array: verify it does NOT also appear as a \`### \` section in the body. A finding goes in ONE place only — inline comment OR body section, never both. If it has a line anchor it goes inline; remove the duplicate body section.
+   2. For each \`### \` section in the body that mentions a specific file and line number: move it to the \`comments\` array as an inline comment and remove it from the body. Body sections are ONLY for concerns with NO specific line anchor.
+
+   note: the first create_pull_request_review submission may error with a one-time diff-coverage nudge listing unread TOC regions. retry the same call to proceed — optionally after reading the listed ranges. the pre-flight will not block again this session.
+
+   **Structured submission (preferred)**: use \`preamble\` + \`changes\` for the reviewed-changes block instead of writing it in \`body\`. Pass \`body\` for ONLY the metadata HTML comment and non-anchored \`### \` sections (if any). The server assembles the full preamble block for you. Example call shape:
+   \`\`\`
+   create_pull_request_review({
+     pull_number: N,
+     preamble: "one sentence on what the PR does",
+     changes: ["**Feature X** — description", "**Migration Y** — description"],
+     body: "<!-- shockbot review metadata ... -->\\n\\n### ⚠️ Non-anchored concern...\\n\\n### ℹ️ Nitpicks\\n...",
+     comments: [{ path: "src/foo.ts", line: 42, body: "..." }, ...],
+     approved: false,
+   })
+   \`\`\`
+   Inline comments are passed via the \`comments\` parameter, not in the body.
+
+   **Body format** — use ONLY the structure from the default format below. Forbidden patterns: \`## \` headings, numbered bold items like \`**1. title**\`, \`## Issues to address\`, \`## Positive notes\`, \`## Minor suggestions\`, or any praise/summary section. Use \`### {emoji} {title}\` for non-anchored issue sections ONLY. No praise sections.
+
+   The opening callout is what the author sees first — pick the one that matches what you want them to do. Five tiers, from loudest to friendliest:
+
+   - \`[!CAUTION]\` — large red banner. Reads as "this will break something."
+   - \`[!IMPORTANT]\` — large purple banner. Reads as "you need to look at this before merging."
+   - \`> ℹ️ ...\` — informational blockquote. Reads as "minor suggestions, nothing blocking."
+   - \`> ✅ ...\` — green friendly blockquote. Reads as "no concerns, mergeable."
+
+   Two reinforcing levers: callout intensity (above) and \`approved\` (which gates the footer Fix-button affordance — Fix renders on every non-approving review, so \`approved: true\` suppresses it). Wrapping mergeable feedback in \`[!IMPORTANT]\` trains users to click Fix on reviews that don't need fixing. Pick the tier the author's actual next action justifies.
+
+   - **critical issues** (blocks merge — bugs, security, data loss, broken core flows):
+     \`approved: false\`. Body opens with \`> [!CAUTION]\\n> This PR introduces ...\`, followed by the PR summary. Include all inline comments via \`comments\`.
+   - **must-address non-critical findings** (real consequences if shipped — incorrect behavior in non-critical paths, missing validation on user input, regressions the author should fix before merge):
+     \`approved: false\`. Body opens with \`> [!IMPORTANT]\\n> ...\`, followed by the PR summary. Reserve this tier for findings with concrete fallout — do NOT use \`[!IMPORTANT]\` for nits, style preferences, or "consider also" suggestions. Include all inline comments via \`comments\`.
+   - **minor suggestions only** (single-line nits, doc/comment polish, defer-able observations, "rough edges"):
+     \`approved: false\`. Body opens with \`> ℹ️ No critical issues — minor suggestions inline.\\n\\n\` followed by the PR summary. Include all inline comments via \`comments\`. Vary the wording after the emoji to fit the review (e.g. "Minor suggestions only.", "Two rough edges worth a look."), but always keep the ℹ️ prefix and keep it short.
+   - **informational observations** (mergeable as-is, nothing actionable — e.g. prior feedback addressed cleanly, surfacing a minor stale doc reference, calling out something noteworthy without recommending a change):
+     \`approved: true\`. Body opens with \`> ✅ No new issues found.\\n\\n\` followed by the PR summary. Do NOT include inline \`comments\` — the ✅ signals "no action needed", which contradicts an actionable anchor; if a point is concrete enough to anchor to a line, downgrade the whole review to "minor suggestions only" (\`approved: false\`) instead.

+        "Re-review a PR after new commits are pushed; focus on new changes since the last review",
+      prompt: `### Checklist
+
+1. **task list**: create your task list for this run as your first action.
+
+2. **checkout**: call \`${t("checkout_pr")}\` — this returns PR metadata, \`diffPath\` (full diff), and \`incrementalDiffPath\` (changes since last reviewed version, if available). read the diff TOC first and use its line ranges as your coverage checklist.
+
+3. **incremental scope**: if \`incrementalDiffPath\` is present, read it to see what changed since the last review. this is a range-diff that isolates the net changes, filtering out base branch noise. if not present, fall back to reviewing the full PR diff and determine what changed since Pullfrog's most recent review.
+
+4. **prior feedback — read AND retire it**: fetch previous reviews via \`${t("list_pull_request_reviews")}\`, then call \`${t("get_review_comments")}\` on each prior shockbot review. Each thread renders as a section whose first line is a fenced tag \`comment author=<login> id=<fullDatabaseId> review=<reviewId> thread=<graphqlId>\`; section headers carry \`[RESOLVED]\` / \`[OUTDATED]\` when relevant. For every **open, Pullfrog-originated** thread, decide and act:
+
+   - **Shockbot-originated** means the FIRST \`comment author=...\` tag in the section is \`author=shockbot[bot]\`. The \`*\` marker on individual comments is unrelated — it flags whether a comment belongs to the queried review, not whether it is the thread root.
+   - **addressed?** read the file at the thread's anchor and judge whether the substantive concern is now resolved by the new commits. Lines being modified isn't enough: reformatting, renaming, or moving the same code elsewhere doesn't address a concern. If the comment raised multiple distinct concerns, ALL must be addressed. The \`[OUTDATED]\` tag means GitHub moved the anchor (line shift, force-push, rename) — it does NOT mean the concern was addressed; re-read the code at its new location before deciding.
+   - **if addressed**: call \`${t("reply_to_review_comment")}\` with the root tag's numeric \`id=\` as \`comment_id\` (NOT the \`thread=\` value — that's a separate GraphQL ID used only by resolve) and a one-line body (e.g. \`Addressed in <short-sha>.\`), then call \`${t("resolve_review_thread")}\` with the root tag's \`thread=\` value as \`thread_id\`. Do this BEFORE drafting the new review so the GitHub thread state aligns with the new review by the time it lands.
+   - **if uncertain or partially addressed**: leave open. False-positive resolutions erode trust faster than false negatives.
+   - **scope**: only retire shockbot-originated threads. Threads from human reviewers belong to those humans to resolve, even if the commit happened to address them.
+
+   The remaining open threads feed step 8's dedup filter — anything already flagged and unchanged by the new commits should not be re-raised. The rolling PR summary snapshot is the durable record of retire activity; you don't need to surface it in the review body.
+
+5. **triage**: orient on the *incremental* changes — domain, seams, external contracts, user-facing surfaces. pull as much context as you need to render a confident review: read related files, grep for callers of changed symbols, check tests that exercise the touched paths. **you are the synthesizer.**
+
+   if the incremental changes are **genuinely trivial**, skip the fan-out entirely and jump to step 10's non-substantive path (do NOT submit a review).
+
+   "Genuinely trivial" (skip): formatting/comment tweaks, import reordering, lockfile regen, mechanical rename of import paths, whitespace-only.
+   "Looks trivial but isn't" (do NOT skip — same anti-patterns as Review mode): 1-line changes to SQL/regex/auth/billing/permissions/signature-verification code; flipping feature-flag defaults or retry/timeout constants; money/tax/HTTP-method/redirect changes; tightening or loosening a comparison operator; mixed diffs with a semantic line buried in formatting.
+   When unsure, treat as non-trivial.
+
+6. **lens decision — 0 or 2+, NEVER 1**.
+
+   The default is **0 lenses**: handle the re-review yourself end-to-end. Most incremental reviews land here — especially thread-reply re-reviews where the user is asking "did you address X?" rather than "review the diff again."
+
+   Dispatch **2+ \`${REVIEWER_AGENT_NAME}\` lenses in parallel** ONLY when ALL of the following are true:
+   - the incremental changes are substantive (>5 files changed AND >200 net new lines), OR touch a high-stakes subsystem (auth, billing, payments, schema migration, webhooks, secrets, RBAC, multi-tenant isolation, cron/scheduling)
+   - you can name 2+ distinct concrete failure modes the new commits plausibly introduce that warrant independent lenses
+   - parallel-orchestrated independent perspectives meaningfully outperform what you'd find solo
+
+   **NEVER dispatch exactly one lens.** Single-lens dispatch adds wall time and cost for no orthogonality benefit. Either go multi-lens (≥2 in parallel) or do the re-review yourself.
+
+   Lens framing follows Review mode: themed lenses (correctness, security, etc.) and subsystem lenses (auth, billing, schema-migration, etc.) — for high-stakes domains lead with the subsystem lens.
+
+7. **fan out (only if step 6 said 2+ lenses)**: dispatch every \`${REVIEWER_AGENT_NAME}\` subagent for this run **IN A SINGLE ASSISTANT TURN, AS MULTIPLE PARALLEL TASK TOOL_USE BLOCKS IN ONE MESSAGE.**
+
+   ⚠️  CRITICAL — PARALLELISM IS THE ONLY REASON LENSES EXIST. ⚠️
+   Default tool-call behavior is **serial dispatch**: emit one Task call, await result, emit next, await, etc. This collapses your fan-out into a sequential review where each lens adds N × (orchestrator-think-time + lens-execution-time) to wall time. **YOU MUST OVERRIDE THIS DEFAULT.** Emit ALL of your Task tool_use blocks in the SAME assistant message, BEFORE you read ANY result from ANY of them.
+
+   ✅ Right pattern: one assistant turn with N Task tool_use blocks → wait → N results arrive together → aggregate.
+   ❌ Wrong pattern: turn 1 = Task(lens A) → turn 2 (after A's result) = Task(lens B). This is the failure mode.
+
+   You can also include your own \`read\` / \`grep\` / \`webfetch\` calls in the SAME turn as the parallel \`${REVIEWER_AGENT_NAME}\` dispatches.
+
+   if a subagent errors out, times out, or returns nothing usable, retry once with the same lens; if it still fails, proceed with partial coverage and note the missing lens in the review body. each subagent gets:
+   - the diff scope (incremental diff path if available, full diff otherwise). do NOT tell them to skip pre-existing issues — that suppresses regressions the new commits amplified; the "issues must be NEW" filter lives at aggregation time (step 8), not in the subagent prompt
+   - **only one lens** — never a multi-section "review for X, Y, and Z" prompt
+   - **a Task \`description\` set to the lens name** — the harness reads this field to label log lines so parallel runs can be told apart.
+   - if the lens touches external contracts, instruct the subagent to verify load-bearing claims via web search and quote source URLs.
+   - ask the subagent to report findings with file paths and NEW line numbers from the full PR diff so you can anchor inline comments.
+
+   delegation discipline:
+   - do NOT summarize the changes for them (biases toward validation frame)
+   - do NOT hand them a curated reading list (let them discover scope)
+   - do NOT pre-shape their output with a finding schema
+   - do NOT mention the other lenses (independence is the point)
+
+8. **aggregate, draft, self-critique**: merge findings (yours + any subagent output if you went multi-lens); de-dup overlaps; trace each finding yourself. drop praise, style preferences, speculative/unverified claims, findings about pre-existing code unrelated to the new commits, anything not actionable, and anything that re-states prior review feedback (heuristic: if the finding's root cause lives in lines the *new commits* added or modified, it's in scope; otherwise drop). also drop **bloat-shaped findings** — proposed fixes that would add defensive checks for cases that can't happen, abstractions used once, comments restating obvious code, tests asserting tautologies, or "just-in-case" guards. subagents are fallible and bias toward recommending changes; the bar for an actionable inline comment is sound + correct + elegant. recommending a change that improves only one of the three (or degrades elegance to nominally improve correctness) makes the codebase worse, not better. To compute "lines the new commits added or modified": if \`incrementalDiffPath\` from step 2 is present, use it directly. Otherwise, take the prior shockbot review's \`commit_id\` (returned alongside each entry from \`${t("list_pull_request_reviews")}\` in step 4) and run \`git diff <prior-review-sha>..HEAD\` to isolate the lines added since that review.
+
+   **Hunt for non-anchored concerns before drafting.** After collecting your anchored findings, deliberately scan for concerns that have no specific line to point at — typically: deletion / cleanup plans for code the new commits replace or shadow; rollout sequencing (what happens to in-flight state during deploy / revert?); coverage gaps the new commits imply but don't add; scope questions that only the human can answer (e.g. is the legacy path going away or is this a long-term dual track?); architectural risks the new commits open up that aren't a single-line bug. On substantial incremental diffs (migrations, refactors, multi-file rewrites, version bumps that change runtime semantics), at least one such concern almost always exists; if you can't think of any, your bar is probably too high.
+
+   for surviving findings that anchor to a specific file and line: **ALWAYS use inline comments** (pass via the \`comments\` parameter). NEVER put a line-anchored finding in the body as a \`### \` section. Every actionable concern with a specific anchor MUST be an inline comment.
+
+   draft inline comments with NEW line numbers from the full PR diff — attach a \`<details>Technical details</details>\` block to any inline comment whose fix is non-trivial or has cross-file implications (see Inline technical details in the format below). every comment must be actionable, 2-3 sentences max in the visible part.
+
+9. **build the review body**: use the same default format as Review mode (preamble + optional cross-cutting \`### \` sections + optional \`### ℹ️ Nitpicks\`) — scoped to the **incremental delta**, not the full PR. The "Reviewed changes" bullets describe what changed since the prior shockbot review (each bullet starts with a past-tense verb, e.g. \`- Extracted shared CLI runtime into a single module\`). Do NOT include a separate "Prior review feedback" checklist — that's tracked in the rolling PR summary snapshot for the next agent run, and surfacing it in the user-facing body is noise (changes that addressed prior feedback are already covered by the Reviewed-changes bullets). In some cases you may receive a complete diff for the whole PR instead of an incremental one; when this happens, determine what changed since Pullfrog's most recent review yourself before drafting bullets.
+
+10. Submit — every run must end with EXACTLY ONE of \`${t("create_pull_request_review")}\` (substantive review) or \`${t("report_progress")}\` (no-review acknowledgement). do NOT call \`create_issue_comment\` for review output.
+
+   Same callout ladder as Review mode — \`[!CAUTION]\` (red, "will break") → \`[!IMPORTANT]\` (purple, "must address before merging") → \`> ℹ️ ...\` (informational, "minor suggestions only") → \`> ✅ ...\` (green friendly, "no concerns"). Same Fix-button lever: the footer renders a Fix button on every non-approving review, so \`approved: true\` suppresses it. Wrapping mergeable feedback in \`[!IMPORTANT]\` trains users to click Fix on reviews that don't need fixing — pick the tier the author's actual next action justifies.
+
+   **MANDATORY pre-submission self-check**: before calling \`${t("create_pull_request_review")}\`, do both of these:
+   1. For each finding already in your \`comments\` array: verify it does NOT also appear as a \`### \` section in the body. A finding goes in ONE place only — inline comment OR body section, never both. If it has a line anchor it goes inline; remove the duplicate body section.
+   2. For each \`### \` section in the body that mentions a specific file and line number: move it to the \`comments\` array as an inline comment and remove it from the body. Body sections are ONLY for concerns with NO specific line anchor.
+
+   Follow these rules:
+   - note: the first create_pull_request_review submission may error with a one-time diff-coverage nudge listing unread TOC regions. retry the same call to proceed — optionally after reading the listed ranges. the pre-flight will not block again this session.
+   - IF NO NEW ISSUES, NON-SUBSTANTIVE CHANGES ONLY (trivial formatting, import reordering, comment tweaks): do NOT submit a review. Instead call \`${t("report_progress")}\` with a 1-2 sentence note explaining no review was warranted (e.g. "No new issues. Changes since last review are formatting-only."). this leaves a visible signal that the run completed.
+   - ELSE IF NEW CRITICAL ISSUES (blocks merge — bugs, security, data loss, broken core flows): call \`${t("create_pull_request_review")}\` with \`approved: false\`, all comments, and the review body. body opens with \`> [!CAUTION]\\n> This PR introduces ...\`, followed by the PR summary using the default format below.
+   - ELSE IF NEW MUST-ADDRESS NON-CRITICAL FINDINGS (real consequences if shipped — incorrect behavior, missing validation, regressions the author should fix before merge): call \`${t("create_pull_request_review")}\` with \`approved: false\`, all comments, and the review body. body opens with \`> [!IMPORTANT]\\n> ...\`, followed by the PR summary using the default format below. Do NOT use this tier for nits, style preferences, or "consider also" suggestions.
+   - ELSE IF NEW MINOR SUGGESTIONS ONLY (single-line nits, doc/comment polish, defer-able observations, "rough edges"): call \`${t("create_pull_request_review")}\` with \`approved: false\`, all comments, and the review body. body opens with \`> ℹ️ No critical issues — minor suggestions inline.\\n\\n\` (vary the wording after ℹ️ to fit the review), followed by the PR summary using the default format below.
+   - ELSE IF INFORMATIONAL OBSERVATIONS (mergeable as-is, but worth surfacing — e.g. prior feedback addressed cleanly with one minor stale doc reference, or a noteworthy positive observation): call \`${t("create_pull_request_review")}\` with \`approved: true\`, NO inline comments, and the review body. body opens with \`> ✅ No new issues found.\\n\\n\` (or similar friendly green opener), followed by the PR summary using the default format below. If a point is concrete enough to anchor to a line, downgrade the whole review to "minor suggestions only" (\`approved: false\`) instead — the ✅ signals "no action needed", which contradicts an actionable anchor.
+   - ELSE IF NO NEW ISSUES, SUBSTANTIVE CHANGES (new functionality, behavior changes, or fixes to prior review feedback): call \`${t("create_pull_request_review")}\` to create a PR review. If all previous reviews have been properly addressed and no new issues were discovered, set \`approved: true\`. body opens with \`> ✅ No new issues found.\\n\\n\`, followed by the PR summary using the default format below.

-   - Are there earlier warnings that might explain the failure?
-   - Is the failure flaky or deterministic?
-
-7. **FIX THE ISSUE** - Make the necessary code changes. Common patterns:
-   - Test assertion failures: fix the code or update the test expectation
-   - Build failures: fix type errors, missing imports, syntax issues

-1. **UNDERSTAND** - Read the request carefully. Only take action if you have high confidence that you understand what is being asked. Take stock of the tools at your disposal.

-2. **CONTEXT** - If the request requires understanding the codebase structure or conventions, gather relevant context. Read AGENTS.md if it exists. Skip this step if the prompt is trivial and self-contained.

+   - if code changes are needed: review your own diff before committing — verify only intended changes are present, no debug artifacts remain, and the changes are clean enough that a senior engineer would approve without hesitation

-4. **CODE CHANGES** - If the task involves making code changes:
-   - Create a branch using \`${ghPullfrogMcpName}/git\` (\`git checkout -b pullfrog/branch-name\`). Branch names should be prefixed with "pullfrog/" and reflect the exact changes you are making. Never commit directly to main, master, or production.

+name: git-archaeology
+description: Investigate how code reached its current state — when a line, function, import, or whole file was changed or deleted, who removed it, and what it looked like before. Use when `git blame` came up empty, when content has been refactored away, or when you need the full evolution of a function across commits.
+---
+
+# Git history archaeology
+
+`git blame` only sees what's still in the working tree. For anything that was
+deleted, moved, or refactored away, you need the commands below. Most agents
+under-use them and end up scrolling through `git log -p` instead.
+
+## Output discipline (read first)
+
+`git log -p` on a long-lived file can dump tens of thousands of lines and blow
+the context window. Always:
+
+1. **Start narrow.** Use `--oneline` or `--stat` to get a list of candidate
+   commits.
+2. **Drill in.** Use `git show <sha> -- <path>` for the diff of one specific
+   commit.
+3. **Scope the search.** Add `--since="3 months ago"`, `-n 20`, or a path
+   restriction (`-- <path>`) so output stays manageable.
+4. **Avoid `git log -p` without a path filter** on any non-trivial repo.
+
+## Decision tree (by agent intent)
+
+### "When did this exact line, string, or import disappear?"
+
+```bash
+git log -S'<exact-string>' --oneline -- <file>
+```
+
+The pickaxe. Returns commits that **changed the count** of that string in the
+file. The most recent hit is typically the removal commit. Add `-p` only after
+you've narrowed to a few candidates.
+
+Notes:
+- `-S` is exact-string by default. Add `--pickaxe-regex` to make it a regex.
+- The argument is "cuddled" with `-S` (`-S'foo bar'`), no space.
+- `-S` will not detect pure in-file moves (count unchanged). Use `-G` for that.
+- `--pickaxe-all` shows the entire changeset of matching commits, useful when
+  a commit changes both a definition and its call sites in other files.
+
+### "When did the diff stop matching this regex?"
+
+```bash
+git log -G'<regex>' --oneline -- <file>
+```
+
+Like `-S` but matches any added or removed hunk line against the regex. Use
+`-G` when:
+- You don't know the exact string but know a pattern.
+- You want to catch in-file moves (`-S` won't).
+- You want to find any diff that touched a pattern, even if the count was
+  preserved (e.g., a refactor that changed call sites without removing the
+  function).
+
+### "How did this function evolve over time?"
+
+```bash
+git log -L :<function-name>:<file>
+```
+
+Every commit that touched the function, with diffs scoped to just the function
+body. Works for languages git understands (most mainstream ones).
+
+### "How did lines N–M evolve?"
+
+```bash
+git log -L <N>,<M>:<file>
+```
+
+### "What's the full history of this file, including across renames?"
+
+```bash
+git log --follow --oneline -- <file>      # overview
+git log --follow -p -- <file>             # with diffs (use sparingly)
+```
+
+`--follow` only works for a single file, not directories.
+
+### "Where was a now-deleted line last present?"
+
+Two-step pattern when you have an exact deleted string:
+
+```bash
+# 1. find a historical commit that contained the string
+git log -S'<deleted-string>' --oneline --all -- <file>
+
+# 2. reverse-blame from that commit to find the last commit it survived in
+git blame --reverse <old-sha>..HEAD -- <file>
+```
+
+The reverse blame tells you, for each line, the last commit it survived in
+before being modified or deleted. Pinpoints the exact deletion commit.
+
+### "This file no longer exists — when was it deleted, and what was in it?"
+
+```bash
+# find all commits that touched the path, even on other branches
+git log --all --full-history --oneline -- <deleted-path>
+
+# the most recent of those is usually the deletion. confirm:
+git show <sha> --stat
+
+# view the file's contents at any commit where it existed
+git show <sha>^:<deleted-path>
+```
+
+If you don't know the path, find it from filename alone:
+
+```bash
+# list all delete events with paths
+git log --all --diff-filter=D --summary | grep -i '<filename>'
+
+# or glob across all branches
+git log --all --oneline -- '**/<filename>.*'
+```
+
+### "Who deleted it, in one shot?"
+
+```bash
+git rev-list -n 1 HEAD -- <deleted-path>     # the deletion commit
+git show $(git rev-list -n 1 HEAD -- <deleted-path>) -- <deleted-path>
+```
+
+### "Restore a deleted file (locally, no commit)"
+
+```bash
+git restore --source=<deletion-sha>^ -- <deleted-path>
+# or, on older git:
+git checkout <deletion-sha>^ -- <deleted-path>
+```
+
+The `^` is critical — at the deletion commit the file is already gone, so we
+read from its parent.
+
+### "Search commit messages, not content"
+
+```bash
+git log --all --grep='<text>' --oneline
+git log --all --grep='<text>' -i --oneline    # case-insensitive
+```
+
+Orthogonal to `-S`/`-G`, which only see the diff.
+
+## Standard workflow for "why does this code look like this"
+
+1. `git log --follow --oneline -- <file>` — overview of commits touching it.
+2. If a recent commit looks suspicious: `git show <sha> -- <file>`.
+3. If you expected to find something and it's missing:
+   `git log -S'<expected-string>' --oneline -- <file>`.
+4. For a specific function's full lifecycle:
+   `git log -L :<fn>:<file>`.
+5. For the deletion point of a known string: pickaxe to find an old commit
+   that contained it, then `git blame --reverse <old-sha>..HEAD -- <file>`.
+
+## Useful flags reference
+
+| Flag | Effect |
+|------|--------|
+| `--all` | Search all refs, not just the current branch. Use when investigating something that may have lived only on a feature branch. |
+| `--full-history` | Keeps commits that history-simplification would otherwise drop. Needed for accurate history across merges. |
+| `--follow` | Track a single file across renames. Single-file only. |
+| `-M` / `-C` | Detect renames (`-M`) and copies (`-C`) when reading diffs. |
+| `--diff-filter=D` | Restrict to commits that **deleted** something. `A`=added, `M`=modified, `R`=renamed. |
+| `--source` | When combined with `--all`, annotate each commit with the ref it was reached from. |
+| `--pickaxe-all` | With `-S`/`-G`, show all files in the matching commit, not just the matching file. |
+| `--pickaxe-regex` | Treat the `-S` argument as a regex. |
+| `--since` / `--until` | Time-bound the search. Cheap perf win on big repos. |
+| `-n <count>` | Cap result count. |
+| `--stat` | Per-commit file stats instead of full patches. Good first pass. |
+
+## Notes and pitfalls
+
+- Always include `--` before paths to disambiguate from refs (e.g.
+  `git log -S'foo' -- src/auth.ts`).
+- `-S` triggers on **count change**. A pure refactor that moves a line within
+  the same file will not match. Use `-G` for those.
+- `-G` runs diff twice and greps; it's slower than `-S`. Scope with paths and
+  `--since` on big repos.
+- Without `--all`, `git log -- <path>` shows nothing if the path never existed
+  on the current branch. When in doubt, add `--all`.
+- `git log --full-history -- <path>` alone has had bugs in some git versions
+  for deleted files; pair with `--all` for reliability.
+- For files that were renamed, `git log -- <new-path>` only shows post-rename
+  history. Use `--follow` (one file) or `git log --all -- <old-path>` when
+  hunting across rename events.
