+# 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
-  - PR review requested
-  - and more...
+### 1. Create a bot account

-Pullfrog is the bridge between your preferred coding agents and GitHub. Use it for:
+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.

- **🤖 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.
+### 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.
-
-[Add to GitHub ➜](https://github.com/apps/pullfrog/installations/new)
-
-<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
-on:
-  workflow_dispatch:
-    inputs:
-      prompt:
-        type: string
-        description: 'Agent prompt'
-
-permissions:
-  contents: read
-
-jobs:
-  pullfrog:
-    runs-on: ubuntu-latest
-    permissions:
-      id-token: write
-      contents: read
-    steps:
-      - name: Checkout code
-        uses: actions/checkout@v6
-        with:
-          fetch-depth: 1
-      - name: Run agent
-        uses: pullfrog/pullfrog@v0
-        with:
-          prompt: ${{ inputs.prompt }}
-        env:
-          # add API keys for the LLM provider(s) you want to use
-          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
-          OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }}
-          GEMINI_API_KEY: ${{ secrets.GEMINI_API_KEY }}
-          XAI_API_KEY: ${{ secrets.XAI_API_KEY }}
-          DEEPSEEK_API_KEY: ${{ secrets.DEEPSEEK_API_KEY }}
-          OPENROUTER_API_KEY: ${{ secrets.OPENROUTER_API_KEY }}
-          MOONSHOT_API_KEY: ${{ secrets.MOONSHOT_API_KEY }}
-
-```
-
-#### 2. Create `triggers.yml`
-
-Create a file at `.github/workflows/triggers.yml`. This workflow listens for GitHub events and calls the `pullfrog.yml` workflow with the event data.
-
-```yaml
-name: Agent Triggers
-
+name: Shockbot Review
 on:
+  pull_request:
+    types: [opened, ready_for_review]
  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: read
-    uses: ./.github/workflows/pullfrog.yml
-    with:
-      # pass the full event payload as the prompt
-      prompt: ${{ toJSON(github.event) }}
-    secrets: inherit
-```
-
-</details>
-->
-
-## Standalone Usage
-
-You can also use `pullfrog/pullfrog` as a step in your own workflows. The action exposes a `result` output that can be consumed by subsequent steps.
-
-### Example: Auto-generate release notes on new tags
-
-```yaml
-name: Release
-on:
-  push:

    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
        with:

-            Compare commits between this tag and the previous tag.
-            Format as markdown: summary paragraph, then ### Features, ### Fixes, ### Breaking Changes sections.
-            Omit empty sections. Be concise.
+          prompt: "Review this pull request"
        env:
-          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}

-          gh release create ${{ github.ref_name }} --title "${{ github.ref_name }}" --notes-file "$notesfile"
+      - name: Run shockbot (mention trigger)
+        if: github.event_name == 'issue_comment'
+        uses: https://git.shockvpn.com/ShockVPN/shockbot@main
+        with:
+          prompt: ${{ github.event.comment.body }}
        env:
-          GH_TOKEN: ${{ github.token }}
-          NOTES: ${{ steps.notes.outputs.result }}
+          BOT_TOKEN: ${{ secrets.BOT_TOKEN }}
+          OLLAMA_HOST: ${{ secrets.OLLAMA_HOST }}
+          GITEA_URL: https://git.shockvpn.com
+          GITEA_PR_NUMBER: ${{ github.event.issue.number }}
 ```

-### Example: Structured Output with Zod Schema
+## Configuration

-You can force the agent to return structured JSON output by providing a JSON schema. This allows you to reliably parse and use the agent's response in subsequent workflow steps.
+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.

-You can define your JSON schema directly or uou can use any validation library that converts to JSON Schema. Here's an example using [Zod](https://zod.dev):
+| 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: Release Check
-on:
-  pull_request:
-    types: [closed]
-
-jobs:
-  check-release:
-    if: github.event.pull_request.merged == true
-    runs-on: ubuntu-latest
-    steps:
-      - uses: actions/checkout@v4
-
-      - name: Install dependencies
-        run: npm install --no-save --no-package-lock zod @actions/core
-
-      - name: Generate Schema
-        id: schema
-        run: |
-          node -e '
-            import { z } from "zod";
-            import { setOutput } from "@actions/core";
-            const schema = z.object({
-              version: z.string().describe("Semantic version number (e.g. 1.0.0)"),
-              isBreaking: z.boolean().describe("Whether this release contains breaking changes"),
-              changelog: z.array(z.string()).describe("List of changes in this release"),
-            });
-            setOutput("schema", JSON.stringify(z.toJSONSchema(schema)));
-          '
-
-      - name: Analyze PR
-        id: analysis
-        uses: pullfrog/pullfrog@v0
-        with:
-          prompt: |
-            Analyze this PR and determine semantic versioning impact.
-            Return a JSON object matching the provided schema.
-          output_schema: ${{ steps.schema.outputs.schema }}
-        env:
-          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
-
-      - name: Process Result
-        run: |
-          # Parse the JSON result using fromJSON()
-          echo "Version: ${{ fromJSON(steps.analysis.outputs.result).version }}"
-          echo "Breaking: ${{ fromJSON(steps.analysis.outputs.result).isBreaking }}"
+with:
+  prompt: "Review this pull request"
+  model: "llama3.1:70b"
 ```
+
+## 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

- * `homeEnv`), so opencode's auto-discovery scans the tmpdir, never the user's
- * working tree. opencode's `Global.Path.config` resolves to
- * `path.join(xdgConfig, "opencode")` and the config layer auto-discovers
- * plugins from every directory in its scan list — including

- *
- * We MUST NOT write into the user's repo working tree. The repo is a checkout
- * the agent operates on; only the agent's own tools (gated by
- * `OPENCODE_PERMISSION`) may modify it. The whole reason we redirect HOME and
- * XDG_CONFIG_HOME is so harness-side files (config, plugins, scratch state)
- * land in the tmpdir.
- *
- * Why this plugin exists: opencode's `task` tool runs subagents in-process and
- * the CLI's `cli/cmd/run.ts` event loop filters `part.sessionID !== sessionID`,
- * so subagent-internal `message.part.updated` events are silently discarded
- * before reaching our parent NDJSON stream. plugins, by contrast, receive
- * EVERY bus event via `bus.subscribeAll()` regardless of session.
- *
- * The plugin re-emits every relevant bus event onto opencode's stdout as a
- * single JSON line wrapped in a sentinel envelope. our `runOpenCode` parser
- * recognises the envelope, unpacks it, and routes the inner part through the
- * existing handlers with a per-session label from `SessionLabeler` so each
- * subagent's tool calls / text appear inline alongside the orchestrator's.
- *
- * Dumb plugin / smart parent split: the plugin emits every part for every
- * session. the parent dedupes against the orchestrator's own session id (which
- * it already knows from the `init` event). this keeps the plugin trivial and
- * keeps the per-session attribution logic on the parent side where the
- * SessionLabeler already lives.
- *
- * Event-name prefixing: the wrapped event-type sentinel is
- * `pullfrog_bus_event` — picked to be unmistakably ours so a future opencode
- * release that introduces a coincidentally-named event type won't collide.

-# `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.

-// ── gemini schema sanitizer ────────────────────────────────────────────────────
-//
-// gemini's generateContent API expects an OpenAPI 3.0 Schema subset, not full
-// JSON Schema. arktype 2.x emits constructs that gemini rejects with errors like:
-//   - "parameters.<field>.enum: only allowed for STRING type"
-//   - "functionDeclaration parameters.<field> schema didn't specify the schema type field"
-//   - "anyOf must be the only field in a schema node"
-//
-// transforms applied here:
-//   1. add `type: "string"` to enum-only schemas. arktype emits string literal
-//      unions as `{enum: ["a","b"]}` without a `type` field — gemini requires
-//      the type declaration for any non-object schema.
-//   2. collapse `{anyOf: [{enum:["a"]}, {enum:["b"]}]}` (older arktype form)
-//      into `{type:"string", enum:[...]}`. also handles `{const:"a"}` branches.
-//   3. when `anyOf` / `oneOf` can't be collapsed, strip sibling fields (`type`,
-//      `description`, `items`, etc.) — gemini rejects `anyOf` alongside any
-//      peer keywords. see opencode #14659.
-//   4. drop `$schema` metadata and rename `$defs` → `definitions` (draft-07
-//      compatibility; gemini doesn't understand either).
-//
-// gating: `isGeminiRouted()` detects gemini-targeted traffic so other
-// providers continue to see the original (untransformed) schema.
-//
-// delivery: fastmcp (3.x) uses `xsschema.toJsonSchema()` which reads
-// `schema["~standard"].jsonSchema.input({target:"draft-07"})` when present
-// (arktype 2.x exposes this). we proxy the whole `~standard` chain so our

-A rolling PR summary lives at \`${filePath}\`. It is your durable cross-run agent context — a functional summary of what this PR does, the subsystems and files it touches, the material behavior of its changes, and any risks or open questions worth carrying forward. It is NOT a chronological log of past review runs; commit-level history can already be reconstructed from \`${t("list_pull_request_reviews")}\`.
-
-How to use it:
-
- read \`${filePath}\` at the START of the run, alongside the diff. it represents what previous agent runs already understood about this PR — absorb it before picking lenses or crafting subagent dispatch prompts. if it's a fresh seed (file is one or two lines), this is a first review and you'll be filling it in from the diff.
- let the snapshot inform triage and dispatch. when it already tracks a risk, your lens prompts to subagents are stronger when they reference that context (e.g. "the JSDoc explicitly scopes to code points — do not flag grapheme-cluster issues" if the snapshot already documents that contract). when something the snapshot tracks is now resolved by new commits, note that. when new commits introduce something the snapshot doesn't yet describe, that's exactly where your fan-out should focus.
- update the file in place to reflect the PR's CURRENT state. revise stale claims, drop resolved risks, add new behavior or risks. accuracy over breadth — every claim must be grounded in the diff. write for the next agent run, not for a human.
- structure however serves THIS PR. there is no required section template. a refactor might organize by renamed export and call-site impact; a feature by capability; a billing change by money path. a compact note of which commit ranges have been reviewed should always be present so future runs scope correctly, but the rest is your call. when the structure works across runs, keep it stable so range-diffs are clean; when the PR's character changes (e.g. scope expands), reshape.
-
-Do NOT call \`${t("create_issue_comment")}\` for the summary — the server reads this file at end-of-run and persists it. The file edit is mandatory regardless of whether a review is submitted; the snapshot feeds the next run.`;

-Follow this structure exactly:
+The body has at most three parts in this exact order:

-<b>TL;DR</b> — 1-3 sentences on what the PR does and why. Focus on intent, not mechanics.
-NOTE: use HTML bold <b>TL;DR</b>, NOT markdown bold **TL;DR**.
+1. **Reviewed changes preamble** — one bolded inline lead-in describing what was reviewed in this run, a bullet list of the substantive changes, and an HTML comment carrying review metadata for downstream agents.
+2. **Cross-cutting issue sections** (zero or more) — one \`### \` heading per concern, with a human-readable problem write-up and a collapsed \`<details>Technical details</details>\` block underneath.
+3. **\`### ℹ️ Nitpicks\`** at the very bottom (only if there are nits worth surfacing in the body) — a flat bullet list, no technical-details block.

-### Key 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.

- **Short human-readable title** — 1 sentence per change. Write a short prose phrase (title case or sentence case); 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 PR from this list alone.
+## 1. Reviewed changes preamble

-<sub><b>Summary</b> ｜ {file_count} files ｜ {commit_count} commits ｜ base: \`{base}\` ← \`{head}\`</sub>
-NOTE: the metadata line goes AFTER the bullet list, not before it.
+Open with a single bolded inline lead-in followed immediately by the bullet list (no \`### Key changes\` heading, no \`<b>TL;DR</b>\`):

-Then for each key change, a ## section with a short descriptive title that reads like a documentation heading (e.g. ## Live todo checklist tracking).
+\`\`\`
+**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.

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**).

+**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. Do NOT mix findings into this list.

-IMPORTANT: Before and After MUST be on a SINGLE blockquote line with an inline <br/> between them. Two separate \`>\` lines creates a double line break.

-CRITICAL — GitHub markdown rendering rule:
-GitHub's markdown parser requires a blank line between ALL block-level elements. This includes transitions between: HTML tags (<br/>, <sub>, <details>, <b>, etc.) and markdown syntax (headings, lists, blockquotes, paragraphs). Without a blank line, GitHub treats the 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.
+\`\`\`
+### {emoji} {short, descriptive title — what's wrong, not what to do}

-Rules:
- \`##\` titles and key-change bullet lead-ins are plain-language summaries; backtick only actual code tokens (files, types, functions) where they appear in the title
- ALL variable names, identifiers, and file names in body text must be in backticks
- ALL file references MUST link to the PR Files Changed view. Use the \`diff-<hex>\` anchor precomputed next to each filename in the \`checkout_pr\` TOC — do NOT run \`sha256sum\` or any other shell command to compute anchors. NEVER fabricate hex strings. If a file is not in the TOC, omit the \`#diff-\` anchor rather than guessing.
- Add <br/> before each ## heading for visual spacing. Do NOT use horizontal rules (---)
- Do NOT include raw diff stats like '+123 / -45' or line counts
- Do NOT include code blocks or repeat diff contents
- Do NOT include a changelog section — the key changes list serves this purpose
- Focus on *intent*, not *what* — the diff already shows what changed
- Get the file count and commit count from the checkout_pr metadata, not by counting manually`;
+{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...".

+
+**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}

+
+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.`;

+   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-intensity ladder as Review mode — \`[!CAUTION]\` (large red, "will break") → \`[!IMPORTANT]\` (large purple, "must address before merging") → \`[!NOTE]\` (small blue, "FYI") → no callout (plain text). And the 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.
+   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 ...\`, then the Reviewed-changes summary.
-   - ELSE IF NEW MUST-ADDRESS NON-CRITICAL FINDINGS (real consequences if shipped — incorrect behavior, missing validation, regressions the author should fix before merge): call \`${t("create_pull_request_review")}\` with \`approved: false\`, all comments, and the review body. body opens with \`> [!IMPORTANT]\\n> ...\`, then the Reviewed-changes summary. Do NOT use this tier for nits, style preferences, or "consider also" suggestions.
-   - ELSE IF NEW MINOR SUGGESTIONS ONLY (single-line nits, doc/comment polish, defer-able observations, "rough edges"): call \`${t("create_pull_request_review")}\` with \`approved: false\`, all comments, and the review body. body opens directly with \`Reviewed the following changes:\\n\` (NO alert blockquote), then the Reviewed-changes summary.
-   - 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 \`> [!NOTE]\\n> ...\` alert, then the Reviewed-changes summary.
