 - **🤖 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
+    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 }}"

+# `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
-
-**output format (XML):**
-```xml

-await mcp.call("gh_pullfrog/get_review_comments", {
-  pull_number: 47,
-  review_id: review.id
-});
-```
-
-#### `list_pull_request_reviews`
-list all reviews for a pull request.
-
-**parameters:**
-- `pull_number` (number): the pull request number
-
-**replaces:** `gh api repos/{owner}/{repo}/pulls/{pull_number}/reviews`
-
-**returns:**
-array of reviews with:
-- review id, body, state (approved/changes_requested/commented)
-- user, commit_id, submitted_at, html_url

-#### `reply_to_review_comment`
-reply to a PR review comment thread explaining how the feedback was addressed.
-
-**parameters:**
-- `pull_number` (number): the pull request number
-- `comment_id` (number): the ID of the review comment to reply to
-- `body` (string): the reply text explaining how the feedback was addressed
-
-**replaces:** `gh api repos/{owner}/{repo}/pulls/{pull_number}/comments/{comment_id}/replies`
-
-**returns:**
-the created reply comment including:
-- comment id, body, html_url
-- in_reply_to_id showing it's a reply to the specified comment
-
-**example:**
-```typescript
-// after addressing a review comment
-await mcp.call("gh_pullfrog/reply_to_review_comment", {
-  pull_number: 47,
-  comment_id: 2567334961,
-  body: "removed the function as requested"
-});
-```
-
-### other tools
-
-see individual files for documentation on other tools:
-- `comment.ts` - create, edit, and update comments
-- `issue.ts` - create issues
-- `pr.ts` - create pull requests
-- `prInfo.ts` - get pull request information
-- `review.ts` - create pull request reviews
-- `selectMode.ts` - select execution mode
-
-## 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** (optional, for complex tasks): analyze requirements, read AGENTS.md and relevant code, produce a step-by-step implementation plan.
+
+2. **setup**: 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\`)
+
+3. **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
+   - review your 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.
+   - commit locally via shell (\`git add . && git commit -m "..."\`)
+
+4. **finalize**:
+   - 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

+  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 \`${ghPullfrogMcpName}/git_fetch\` to fetch the base branch.
+
+2. **Merge Attempt**:
+   - Run \`git merge origin/<base_branch>\` via shell.
+   - If it succeeds automatically, push via \`${ghPullfrogMcpName}/push_branch\` and report success.
+   - If it fails (conflicts), resolve them manually.
+
+3. **Resolve Conflicts**:
+   - Run \`git status\` or parse the merge output to find the list of conflicting files.
+   - For each conflicting file: read it, find the conflict markers (\`<<<<<<<\`, \`=======\`, \`>>>>>>>\`), understand the code context, and rewrite the file with the correct resolution. Remove all markers.
+   - Verify the file syntax is correct after resolution.
+
+4. **Finalize**:
+   - Run a final verification (build/test) to ensure the resolution works.
+   - \`git add . && git commit -m "resolve merge conflicts"\`
+   - Push via \`${ghPullfrogMcpName}/push_branch\`

+
+1. Checkout the PR branch via \`${ghPullfrogMcpName}/checkout_pr\`.

+2. Fetch review comments via \`${ghPullfrogMcpName}/get_review_comments\`.
+
+3. For each comment:
+   - understand the feedback
+   - make the code change using your native tools
+   - record what was done
+
+4. Quality check:
+   - 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 "..."\`)

+  Review: `### Checklist
+
+1. Checkout the PR via \`${ghPullfrogMcpName}/checkout_pr\` — this returns PR metadata and a \`diffPath\`. Read the diff to identify the major areas of change.
+
+2. For each area of change:
+   - read the diff and trace data flow, check boundaries, and verify assumptions
+   - plan your investigation: identify the highest-risk areas (tricky state transitions, boundary crossings, assumption chains) and prioritize depth over breadth
+   - use \`${ghPullfrogMcpName}/get_pull_request\` and other read-only GitHub tools for additional context
+   - if the PR removes features, deletes exports, renames concepts, or changes architectural patterns, run a dedicated impact analysis: list what changed, then use grep across code, tests, docs (\`docs/\`, \`wiki/\`), comments, configs, and UI to find stale references
+   - report impact-analysis findings in the summary body, ordered by severity (runtime breakage > incorrect docs > stale comments)
+   - draft inline comments with NEW line numbers from the diff — every comment must be actionable (2-3 sentences max)
+   - use GitHub permalink format for code references
+
+3. Self-critique: review all drafted comments and drop any that are praise, style preferences, speculative/unverified claims, about pre-existing code unrelated to the PR, or not actionable.
+
+4. Submit:
+   - **actionable issues found**: call \`${ghPullfrogMcpName}/create_pull_request_review\` with all comments, a 1-3 sentence summary body, and \`approved: false\`. Then call \`report_progress\` with a 1-sentence summary.
+   - **no actionable issues found**: do NOT submit a review. Call \`${ghPullfrogMcpName}/report_progress\` with a brief note (e.g., "Reviewed — no issues found.").`,
+
+  IncrementalReview: `### Checklist
+
+1. Checkout the PR via \`${ghPullfrogMcpName}/checkout_pr\` — this returns PR metadata, \`diffPath\` (full diff), and \`incrementalDiffPath\` (changes since last reviewed version, if available).
+
+2. If \`incrementalDiffPath\` is present, read it to see what changed since the last review. This is a range-diff that isolates the net changes, filtering out base branch noise. If not present, fall back to reviewing the full PR diff.
+
+3. Fetch previous reviews via \`${ghPullfrogMcpName}/list_pull_request_reviews\`. For the most recent Pullfrog review, call \`${ghPullfrogMcpName}/get_review_comments\` with the review ID to retrieve specific prior line-level feedback.
+
+4. For each area of the new changes:
+   - review the incremental diff while using the full diff for context
+   - check whether prior review feedback was addressed by the new commits
+   - trace data flow, check boundaries, verify assumptions, consider lifecycle, spot performance issues
+   - if the new commits remove, rename, or deprecate anything, run impact analysis with grep across code/tests/docs/comments/configs to find stale references and include those findings in the summary body
+   - never repeat prior feedback. if the author did not address an earlier comment, assume it was intentionally declined; only comment on genuinely new issues introduced by the new commits
+   - draft inline comments with NEW line numbers from the full PR diff — every comment must be actionable (2-3 sentences max)
+
+5. Self-critique: drop any comments that are praise, style preferences, speculative, about pre-existing code, or not actionable.
+
+6. Submit:
+   - **actionable issues found**: call \`${ghPullfrogMcpName}/create_pull_request_review\` with \`approved: false\`, all comments, and an **empty body** — inline comments speak for themselves, and a top-level body clutters the PR conversation on every re-review cycle. Then call \`report_progress\` with a 1-sentence summary.
+   - **no actionable issues, but substantive changes or prior fixes confirmed**: post a brief comment (1-3 sentences) via \`${ghPullfrogMcpName}/create_issue_comment\` confirming the review happened and listing which prior review issues were resolved. Substantive = new functionality, behavior changes, architectural changes, or fixes to previously flagged issues.
+   - **no actionable issues, non-substantive changes only** (e.g., trivial formatting, import reordering, comment tweaks with no functional impact): do NOT submit a review. Call \`${ghPullfrogMcpName}/report_progress\` with a brief note (e.g., "Re-reviewed — no new issues found.").`,
+
+  Plan: `### Checklist

+1. Analyze the task and gather context:
+   - read AGENTS.md and relevant codebase files

+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. Revise the plan based on the user's request:
+   - incorporate the current plan (\`previousPlanBody\`) and the user's revision request

+   - produce a structured plan with clear milestones
+3. Call \`${ghPullfrogMcpName}/report_progress\` with the full revised plan text and \`{ target_plan_comment: true }\` so it updates the existing plan comment (not the progress comment).
+4. Then post a short note to the progress comment (e.g. "Plan has been updated in the comment above.") via \`${ghPullfrogMcpName}/report_progress\` so it is not left as "Leaping...".`,

+2. Fetch check suite logs via \`${ghPullfrogMcpName}/get_check_suite_logs\`.
+
+3. **CRITICAL**: verify the failure was INTRODUCED BY THIS PR before fixing. If unrelated, abort and report.
+
+4. Diagnose and fix:
+   - read the workflow file, reproduce locally with the EXACT same commands CI runs
+   - fix the issue using your native file and shell tools
+   - verify the fix by re-running the exact CI command
+   - 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 without hesitation.

+   - 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
+
+3. Finalize:

+   - 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.
