 - **🤖 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.

 ## Get started

 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.

+## 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:
+    tags: ['v*']
+
+permissions:
+  contents: write
+
+jobs:
+  release:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Checkout
+        uses: actions/checkout@v4
+        with:
+          fetch-depth: 0
+
+      - name: Generate release notes
+        id: notes
+        uses: pullfrog/pullfrog@v0
+        with:
+          prompt: |
+            Generate release notes for ${{ github.ref_name }}.
+            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.
+        env:
+          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+
+      # write to file to avoid shell escaping issues with special characters
+      - name: Create GitHub release
+        run: |
+          notesfile="$RUNNER_TEMP/release-notes-$GITHUB_RUN_ID.md"
+          printf '%s' "$NOTES" > "$notesfile"
+          gh release create ${{ github.ref_name }} --title "${{ github.ref_name }}" --notes-file "$notesfile"
+        env:
+          GH_TOKEN: ${{ github.token }}
+          NOTES: ${{ steps.notes.outputs.result }}
+```
+
+### Example: Structured Output with Zod Schema
+
+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.
+
+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):
+
+```yaml
+name: Release Check
+on:
+  pull_request:
+    types: [closed]
+
+jobs:
+  check-release:
+    if: github.event.pull_request.merged == true

+# `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.

-# gh_pullfrog MCP Tools
-
-this directory contains the mcp (model context protocol) server tools for interacting with github.
-
-## available tools
-
-### check suite tools
-
-#### `get_check_suite_logs`
-get workflow run logs for a failed check suite with intelligent log analysis.
-
-**parameters:**
- `check_suite_id` (number): the id from check_suite.id in the webhook payload
-
-**replaces:** `gh run list` and `gh run view --log`
-
-**returns:**
-structured failure information for each failed job:
- `_instructions`: explains how to use each field
- `failed_jobs[]`: array of failed job results, each containing:
-  - `job_id`, `job_name`, `job_url`: job identification
-  - `failed_steps`: which CI steps failed (e.g., "Step 6: Run tests")
-  - `log_index`: array of interesting lines (errors, warnings, failures) with line numbers
-  - `excerpt`: ~80 line curated window around the last error
-  - `full_log_path`: path to complete log file for deeper investigation
-
-**log_index types:**
- `error`: lines matching `##[error]`, `Error:`, `ERR_`, `exit code N`
- `warning`: lines matching `##[warning]`, `WARN`
- `failure`: lines matching `N failed`, `FAIL`, `✕`
- `trace`: stack trace lines (deduplicated)
-
-**workflow for using results:**
-1. scan `log_index` to see where errors/warnings/failures are located in the log
-2. read `excerpt` for immediate context around the main error
-3. if excerpt doesn't show what you need, read specific line ranges from `full_log_path`
-4. check `failed_steps` and read the workflow yml to understand what command failed
-
-**example:**
-```typescript
-// when handling a check_suite_completed webhook
-const result = await mcp.call("gh_pullfrog/get_check_suite_logs", {
-  check_suite_id: check_suite.id
-});
-
-// result.failed_jobs[0].log_index shows:
-// [
-//   { line: 181, content: "WARN  Failed to create bin...", type: "warning" },
-//   { line: 1079, content: "Error: expect(received).toBe(expected)", type: "error" },
-//   ...
-// ]
-// use these line numbers to read specific sections from full_log_path
-```
-
-### review tools
-
-#### `get_review_comments`
-get all line-by-line comments for a specific pull request review, including full thread context for replies.
-
-**parameters:**
- `pull_number` (number): the pull request number
- `review_id` (number): the id from review.id in the webhook payload
- `approved_by` (string, optional): only return comments this user gave a 👍 to
-
-**replaces:** `gh api repos/{owner}/{repo}/pulls/{pull_number}/reviews/{review_id}/comments`
-
-**returns:**
- `commentsPath`: path to XML file with full comment details
- `reviewer`: github username of the review author
- `count`: number of comments to address
-

-  review_id: review.id
-});
-```
-
-#### `list_pull_request_reviews`
-list all reviews for a pull request.
-
-**parameters:**
- `pull_number` (number): the pull request number

-  comment_id: 2567334961,
-  body: "removed the function as requested"
-});
-```
-
-### output tools
-
-#### `set_output`
-set the action output for consumption by subsequent workflow steps. useful when pullfrog is used as a step in a user-defined CI workflow (e.g., generating release notes).
-
-**parameters:**
- `value` (string): the output value to expose
-
-**returns:**
- `success`: true on success
-
-the value will be available as the `result` output of the action, accessible via `${{ steps.<step-id>.outputs.result }}`.
-
-**example:**
-```typescript
-// when generating content for downstream consumption
-await mcp.call("gh_pullfrog/set_output", {
-  value: "## Release Notes\n\n- Added new feature X\n- Fixed bug Y"
-});
-```
-
-**usage in workflow:**
-```yaml
- uses: pullfrog/pullfrog@v1
-  id: notes
-  with:
-    prompt: "Generate release notes for v2.0.0"
-
- uses: softprops/action-gh-release@v1
-  with:
-    body: ${{ steps.notes.outputs.result }}
-```
-
-### other tools
-
-see individual files for documentation on other tools:
- `comment.ts` - create, edit, and update comments
- `issue.ts` - create issues
- `output.ts` - set action output for workflow consumption
- `pr.ts` - create pull requests
- `prInfo.ts` - get pull request information
- `review.ts` - create pull request reviews
- `delegate.ts` - delegate task to a subagent with a specific mode and effort level
-
-## usage in agents
-
-agents should prefer using the mcp tools provided by this server. the `gh` cli is available as a fallback if needed, but mcp tools handle authentication and provide better integration.
-
-the agent instructions automatically include guidance on using these tools.

+
+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.`,
+
+  ResolveConflicts: `### Checklist
+
+1. **Setup**:
+   - Call \${ghPullfrogMcpName}/checkout_pr to get the PR branch.
+   - Call \${ghPullfrogMcpName}/get_pull_request to identify the base branch (e.g., 'main').
+   - Call \${ghPullfrogMcpName}/git_fetch to fetch the base branch.
+
+2. **Merge Attempt**:
+   - Run \`git merge origin/<base_branch>\` via shell.
+   - If it succeeds automatically: Great! Push via \${ghPullfrogMcpName}/push_branch and report success.
+   - If it fails (conflicts): You must resolve them.
+
+3. **Delegation (if conflicts exist)**:
+   - Run \`git status\` or parse the merge output to find the list of conflicting files.
+   - Delegate to a subagent (or multiple in parallel if many files) to resolve the conflicts.
+   - **Instructions for subagent**:
+     - "You are resolving merge conflicts in these files: [list]."
+     - "For each file: read it, find the conflict markers (<<<<<<<, =======, >>>>>>>), understand the code context, and rewrite the file with the correct resolution. Remove all markers."
+     - "After resolving, verify the file syntax is correct."
+     - "Call \${ghPullfrogMcpName}/set_output with a summary of what you resolved."
+   - Note: Subagents cannot run git commands. They only edit the files.
+
+4. **Finalize**:
+   - After subagents return:
+   - Run a final verification (build/test) to ensure the resolution works.
+   - \`git add .\`
+   - \`git commit -m "Resolve merge conflicts"\`
+   - \${ghPullfrogMcpName}/push_branch
+   - \${ghPullfrogMcpName}/report_progress
+`,
+
+  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.
+
+### Crafting each task
+
+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
+- if subagents found actionable issues: submit one \`${ghPullfrogMcpName}/create_pull_request_review\` with \`approved: false\`, the merged comments, and a unified summary body
+- if no subagent found actionable issues: submit with \`approved: true\` and a brief positive summary (no inline comments)
+- call \`${ghPullfrogMcpName}/report_progress\` with the summary
+
+Use max effort for thorough reviews.`,
+
+  IncrementalReview: `### Checklist
+
+1. Checkout the PR via \`${ghPullfrogMcpName}/checkout_pr\` — this returns PR metadata and a \`diffPath\`. Read the diff to identify the major areas of change.
+2. Generate the incremental diff using the \`before_sha\` from EVENT DATA: \`git diff <before_sha>...HEAD\`. This isolates only the new commits. If the command fails (e.g., force-push rewrote history), fall back to reviewing the full PR diff.
+3. Fetch previous reviews via \`${ghPullfrogMcpName}/list_pull_request_reviews\`. For the most recent Pullfrog review, call \`${ghPullfrogMcpName}/get_review_comments\` with the review ID to retrieve specific prior line-level feedback. Include the prior review summary and comment details when crafting subagent tasks.
+4. Delegate multiple subagents in a single \`${ghPullfrogMcpName}/delegate\` call, each focused on a specific area of the new changes. Provide both the full diff path and the incremental diff.
+5. After all subagents return, consolidate their findings into a single review.
+
+### Crafting each task
+
+Each task in the \`tasks\` array should include:
+- the full diff file path AND the incremental diff (so the subagent can see both new changes and full context)
+- what specific area/aspect to focus on
+- instruct it to prioritize reviewing code in the incremental diff while using the full diff for context and to catch any changes not covered by the incremental diff
+- include the prior review comments (from step 3) so the subagent knows what feedback was already given — instruct it to avoid repeating prior issues and to note whether prior feedback was addressed by the new commits
+- instruct it to actively hunt for problems: trace data flow, check boundaries, explore failure modes, verify assumptions, consider lifecycle, spot performance issues
+- draft inline comments with NEW line numbers from the full PR diff — every comment must be actionable (2-3 sentences max)
+- call \`${ghPullfrogMcpName}/set_output\` with a JSON object: \`{ "summary": "...", "comments": [{ "path": "file.ts", "line": 42, "body": "..." }, ...] }\`
+
+### Post-delegation

+- call \`${ghPullfrogMcpName}/report_progress\` with the summary
+
+Use max effort for thorough reviews.`,
+
+  Plan: `### Checklist
+
+1. Include in its prompt:
+   - the task to plan for
+   - relevant codebase context (file paths, architecture notes from AGENTS.md)
+   - instruct it to produce a structured, actionable plan with clear milestones
+   - IMPORTANT: instruct it to return the full plan text via \`${ghPullfrogMcpName}/set_output\` as well-structured markdown — do NOT create plan files, do NOT save to disk
+2. After the subagent completes, call \`${ghPullfrogMcpName}/report_progress\` with the full plan text from the subagent's output. The progress comment must contain the complete plan — not a file path or summary.
+
+### Effort
+
+Use mini or auto effort.`,
+
+  PlanEdit: `### Checklist (editing existing plan)
+
+An existing plan comment was found for this issue. Update that comment with the revised plan — do not create a new plan comment.
+
+1. Use \`previousPlanBody\` from this response as the plan to revise; do not call \`get_issue\` or \`get_issue_comments\`.
+2. When delegating, the subagent prompt must contain:
+   - the current plan (\`previousPlanBody\`) and the user's revision request
+   - relevant codebase context (file paths, architecture notes from AGENTS.md)
+   - instructions to produce a structured plan with clear milestones and to return the full plan via \`${ghPullfrogMcpName}/set_output\` as markdown (do not create plan files or save to disk)
+3. After the subagent completes, call \`${ghPullfrogMcpName}/report_progress\` with the full plan text and \`{ target_plan_comment: true }\` so the revised plan updates the existing plan comment (not the progress comment).
+4. Then post a short note to the progress comment (e.g. "Plan has been updated in the comment above.") via \`${ghPullfrogMcpName}/report_progress\` so it is not left as "Leaping...".

+Use mini or auto effort.`,

+  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.`,

+## Tools
+
+Your tools are limited to:
+- **File operations**: \`${ghPullfrogMcpName}/file_read\`, \`file_write\`, \`file_edit\`, \`file_delete\`, \`list_directory\`. Native file tools (Read, Write, StrReplace, etc.) are disabled — use the MCP versions.
+- **Shell**: \`${ghPullfrogMcpName}/shell\` (if available). Use this for local git operations (\`git add\`, \`git commit\`, \`git diff\`, \`git log\`, \`git status\`), running tests, builds, and linters.
+- **Read-only GitHub**: \`get_pull_request\`, \`get_issue\`, \`get_issue_comments\`, \`get_issue_events\`, \`get_review_comments\`, \`list_pull_request_reviews\`, \`get_check_suite_logs\`, \`get_commit_info\`.
+- **Output**: \`${ghPullfrogMcpName}/upload_file\`, \`${ghPullfrogMcpName}/set_output\`.
+
+## Output
+
+When you finish, you MUST call \`${ghPullfrogMcpName}/set_output\` with your results. This is how your work gets back to the orchestrator — if you don't call it, your output is lost. Structure output as the instructions request. For research tasks, use well-organized markdown.`;

+1. **CHECKOUT** - Call ${ghPullfrogMcpName}/checkout_pr with the PR number. This gives you the full PR diff via \`diffPath\`.
+
+2. **INCREMENTAL DIFF** - EVENT DATA contains \`before_sha\` (the HEAD before this push). Generate the incremental diff:
+   \`git diff <before_sha>...HEAD\`
+   This shows the changes introduced by this push. Cross-reference with previous reviews (step 3) to confirm coverage of all unreviewed changes — the full PR diff fills any gaps.
+   **If the diff command fails** (e.g., force-push rewrote history), fall back to reviewing the full PR diff from step 1.
+
+3. **FETCH PREVIOUS REVIEWS** - Use ${ghPullfrogMcpName}/list_pull_request_reviews to find previous Pullfrog reviews. For the most recent one, call ${ghPullfrogMcpName}/get_review_comments with the review ID to see specific line-level feedback. This lets you avoid repeating issues and assess whether prior feedback was addressed by the new commits.
+
+4. **ANALYZE** - Read the incremental diff to understand the new changes. Use the full PR diff for surrounding context and to catch any changes not covered by the incremental diff.
+   - **Understand the change**: What is new or modified since the last review?
+   - **Evaluate the approach**: Are the new changes sound? Do they address prior feedback?
+
+5. **INVESTIGATE** - Hunt for problems in the new code using the same techniques as a full review:
+   - Trace data flow, check boundaries, explore failure modes, verify assumptions, consider lifecycle, spot performance issues.
+   - Focus investigation on code that changed in the incremental diff, but trace its effects through the broader codebase.
+   - Do NOT repeat feedback already given in previous reviews unless it was not addressed.
+
+6. **DRAFT LINE-BY-LINE COMMENTS** - Every comment must be actionable. 2-3 sentences max. Use the NEW line number from the full PR diff. NO COMPLIMENTS. NO NITPICKING.
+
+7. **WRITE SUMMARY** - Draft a 1-3 sentence summary for the review body. Focus on what changed since the last review and whether the new changes are sound. If issues were found, include urgency level. If no issues were found, write a brief approval summary.
+
+8. **SUBMIT** — Use ${ghPullfrogMcpName}/create_pull_request_review:
+   - \`body\`: The summary from step 7
+   - \`comments\`: The inline comments from step 6
+   - \`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."
