 - **🤖 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)));
+          '

+          prompt: |

+ * - managed-settings.json: filesystem sandbox — deny /proc, /sys reads
+ * - MCP ShellTool provides restricted shell (filtered env, no secrets)
+ * - MCP server injected via --mcp-config (not replacing project config)
+ * - ASKPASS handles git auth separately (token never in subprocess env)
+ *
+ * the agent process itself gets full env (needs LLM API keys, PATH, etc.).

+ * OpenToad agent — secure harness around OpenCode CLI.
+ *
+ * transparently wraps OpenCode with a security layer:
+ * - bash: "deny" via OPENCODE_CONFIG_CONTENT (agent cannot shell out)
+ * - OPENCODE_PERMISSION: filesystem sandbox — deny all external paths except /tmp
+ * - untrusted .opencode/plugins/ and .opencode/tools/ deleted before launch
+ * - MCP ShellTool provides restricted shell (filtered env, no secrets)
+ * - MCP server injected alongside project config (not replacing)
+ * - ASKPASS handles git auth separately (token never in subprocess env)
+ *
+ * the agent process itself gets full env (needs LLM API keys, PATH, etc.).
+ * security is enforced at the tool layer, not the process layer.

+# `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
-

-  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

-  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.

+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.
+
+1-2 sentences of explanation. Break up text with tables, blockquotes, or lists — NEVER 3+ plain paragraphs in a row.
+
+If a change warrants deeper explanation, use a blockquoted details/summary framed as a question:

+
+Single-feature PRs: skip the ## sections. Fold before/after and explanation into the header after key changes.
+
+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.
+
+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. Compute anchors by running \`echo -n 'path/to/file.ts' | sha256sum\` via shell for each file. NEVER fabricate hex strings — run the actual command. If shell is unavailable, 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

+2. **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 pullfrog/branch-name\`)
 
-4. Understand the requirements and any existing plan
+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
 
-5. 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.
+4. **self-review**: delegate a read-only subagent to review your diff. the subagent must ONLY read files, grep, and search — no MCP tools, no writes, no shell commands, no side effects. provide it with the output of \`git diff\` and instruct it to look for bugs, logic errors, missing edge cases, and unintended changes. review its findings, address any valid points, and discard nitpicks or false positives. then:
+   - verify only intended changes are present, no debug artifacts or commented-out code remain, and no unrelated files were modified
+   - commit locally via shell (\`git add . && git commit -m "..."\`)
 
-6. 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.
+5. **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
 
-7. 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.

-9. 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.
-   - **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.
-
-10. 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>)
-    \`\`\`
-  
-  **IMPORTANT**: Do NOT overwrite a good comment with links/details with a generic message like "I have completed the task. Please review the PR." If your previous report_progress call already contains all the necessary information and links, skip the final call entirely.

-   - **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. 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 \`${t("get_pull_request")}\` and other read-only GitHub tools for additional context
+   - if the PR removes features, deletes exports, renames identifiers, 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)

+   - for large or cross-cutting PRs that touch disparate subsystems, consider delegating read-only subagents to investigate areas in parallel. subagents must ONLY read files, grep, and search — no MCP tools, no writes, no shell commands, no side effects. collect their findings and use them to draft comments.

-   - **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?
-   - Do NOT stop at "this looks reasonable." Dig until you either find a problem or have concrete evidence there isn't one.
+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. **DRAFT LINE-BY-LINE COMMENTS** - For each issue found, draft an inline comment on the specific line. Use the NEW line number from the diff (second column: \`| OLD | NEW | TYPE | CODE\`). If no issues found, skip to step 6.
+4. Submit — ALWAYS submit exactly one review via \`${t("create_pull_request_review")}\`.
+   Do NOT call \`report_progress\` — the review is the final record and the progress
+   comment will be cleaned up automatically.
 
-5. **FILTER LINE-BY-LINE COMMENTS** - Each inline comment must be actionable. Remove anything that doesn't require action:
-   - **Not actionable → no comment**: Do NOT create inline comments for compliments (e.g., "this looks clean", "nice refactor") or general observations. These waste reviewer attention.
-   - **Actionable by agent → keep**: Bugs, logic errors, missing error handling, security issues, race conditions, resource leaks, incorrect assumptions.
-   - **Requires human decision → keep**: If something needs human judgment (architectural choice, product decision, tradeoff evaluation), create a comment clearly stating what decision is needed and why.
-   - Remove style-only comments (formatting, naming conventions) unless they cause real confusion.
+   - **critical issues** (blocks merge — bugs, security, data loss):
+     \`approved: false\`. Body begins with a GitHub alert blockquote, e.g.:
+     \`> [!CAUTION]\\n> This PR introduces a race condition in ...\`
+     Follow with a brief summary if needed. Include all inline comments.
+   - **recommended changes** (non-critical):
+     \`approved: false\`. Body begins with a GitHub alert blockquote, e.g.:
+     \`> [!IMPORTANT]\\n> Consider adding input validation for ...\`
+     Follow with a brief summary if needed. Include all inline comments.
+   - **no actionable issues**:
+     \`approved: true\`, body: "Reviewed — no issues found."`,

-6. **WRITE SUMMARY** - Draft a 1-3 sentence summary for the review body. Include urgency level and any concerns about code outside the diff.
+1. Checkout the PR via \`${t("checkout_pr")}\` — this returns PR metadata, \`diffPath\` (full diff), and \`incrementalDiffPath\` (changes since last reviewed version, if available).
 
-7. **SUBMIT** — Use ${ghPullfrogMcpName}/create_pull_request_review:
-   - \`body\`: The summary from step 6
-   - \`comments\`: The filtered inline comments from step 5
+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.
 
-${permalinkTip}
-`,
+3. Fetch previous reviews via \`${t("list_pull_request_reviews")}\`. For the most recent Pullfrog review, call \`${t("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. 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)
+   - for large or cross-cutting PRs, consider delegating read-only subagents for parallel investigation. subagents must ONLY read files, grep, and search — no MCP tools, no writes, no shell commands, no side effects. collect their findings and use them to draft comments.
+
+5. Self-critique: drop any comments that are praise, style preferences, speculative, about pre-existing code, or not actionable.
+
+6. **Summarize**: build two distinct sections for the review body:
+   a. **Reviewed changes**: summarize at the logical-change level, not per-file. each bullet starts with a past-tense verb (e.g. \`- Extracted shared CLI runtime into a single module\`, \`- Renamed package to pullfrog\`). avoid file paths unless they add clarity. if the changes can be described in one sentence, use one sentence — no bullets needed.
+   b. **Prior review feedback** (only if any were addressed): list only the prior review comments that WERE addressed by the new commits (\`- [x] safeParse instead of parse — addressed\`). omit unaddressed comments. omit this entire section if nothing was addressed. a change can appear in both sections.
+   - no headings, no tables, no prose paragraphs in either section — just bullets
+   - in some cases you may receive a complete diff for the whole pull request instead of an incremental one. when this happens, you will need to determine what changes have happened since Pullfrog's most recent review.
+
+7. Submit — Do NOT call \`report_progress\` or \`create_issue_comment\` — the review is the final record and the progress comment will be cleaned up automatically. the review body always includes the reviewed changes from step 6a. append \`Prior review feedback:\\n\` with the checklist from step 6b only if any prior comments were addressed. Follow these rules:
+   - IF NO NEW ISSUES, NON-SUBSTANTIVE CHANGES ONLY (trivial formatting, import reordering, comment tweaks): do NOT submit a review. Do NOT call \`report_progress\`. Exit — the progress comment will be cleaned up automatically.
+   - ELSE IF NEW CRITICAL ISSUES (blocks merge): call \`${t("create_pull_request_review")}\` with \`approved: false\`, all comments, and the review body. body opens with a GitHub alert blockquote (e.g. \`> [!CAUTION]\\n> This PR introduces ...\`), then the reviewed changes summary and prior feedback (if any).
+   - ELSE IF NEW RECOMMENDED CHANGES (non-critical): call \`${t("create_pull_request_review")}\` with \`approved: false\`, all comments, and the review body. body opens with \`> [!IMPORTANT]\\n> ...\` alert, then the reviewed changes summary and prior feedback (if any).
+   - ELSE IF NO NEW ISSUES, SUBSTANTIVE CHANGES (new functionality, behavior changes, or fixes to prior review feedback): call \`${t("create_pull_request_review")}\` to create a PR review. If all previous reviews have been properly addressed and no new issues were discovered, you can set \`approved: true\`. body opens with \`No new issues.

+      prompt: `### Checklist
 
-**CRITICAL RULE**: Only fix issues that were INTRODUCED BY THIS PR. If the CI failure is unrelated to the PR's changes, you MUST abort without committing anything and report why.
+1. Checkout the PR branch via \`${t("checkout_pr")}\`.
 
-1. **GET FAILURE INFO** - Call ${ghPullfrogMcpName}/get_check_suite_logs with the check_suite_id from EVENT DATA. This returns:
-   - \`log_index\`: array of interesting lines (errors, warnings, failures) with line numbers - scan this first
-   - \`excerpt\`: curated ~80 lines around the main error - read this for immediate context
-   - \`full_log_path\`: path to complete log file - read specific line ranges if needed
-   - \`failed_steps\`: which CI steps failed (e.g., "Step 6: Run tests")
+2. Fetch check suite logs via \`${t("get_check_suite_logs")}\`.
 
-2. **CHECKOUT AND ASSESS CAUSATION** - Use ${ghPullfrogMcpName}/checkout_pr to get the PR diff. BEFORE attempting any fix, you MUST determine if this PR caused the failure:
-   
-   **Ask yourself**: "Could the changes in this PR have caused this failure?"
-   
-   - Read the PR diff carefully - what files were modified?
-   - What is failing? (test file, module, assertion)
-   - Is there a PLAUSIBLE CONNECTION between the PR changes and the failure?
-   
-   **ABORT immediately if any of these are true:**
-   - The failing test/file was NOT touched by this PR AND doesn't depend on changed code
-   - The error is infrastructure-related (network timeout, runner OOM, service unavailable)
-   - The error is a flaky test that passes/fails randomly
-   - The error existed before this PR (pre-existing bug in main branch)
-   - The error is in a dependency update not introduced by this PR
-   
-   **When aborting**, use ${ghPullfrogMcpName}/report_progress to explain:
-   "This CI failure appears unrelated to the PR's changes. [Describe the failure]. [Explain why it's not caused by the PR]. No changes made."
-   
-   **Only proceed** if there's a clear, logical connection between the PR changes and the failure.
+3. **CRITICAL**: verify the failure was INTRODUCED BY THIS PR before fixing. If unrelated, abort and report.
 
-3. **UNDERSTAND HOW CI RUNS** - Read the workflow file to understand exactly what commands CI runs:
-   - Look at \`.github/workflows/*.yml\` files
-   - Find the job/step that failed (from \`failed_steps\`)
-   - Note the EXACT command (e.g., \`pnpm -r test --filter=action\`, not just \`pnpm test\`)
-   - Check for any CI-specific environment variables or setup steps
+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.
+   - commit locally via shell (\`git add . && git commit -m "..."\`)
 
-4. ${dependencyInstallationStep}
+5. Finalize:
+   - confirm a clean working tree, then push via \`${t("push_branch")}\` (same push/prepush guidance as Build mode in *SYSTEM*)
+   - call \`${t("report_progress")}\` with the diagnosis and fix summary (or the exact push error if push failed)
 
-5. **REPRODUCE LOCALLY** - Run the EXACT same command that CI runs:
-   - Do NOT simplify (e.g., don't run \`pnpm test\` if CI runs \`pnpm -r test --filter=action\`)
-   - Check if CI uses specific flags, filters, or environment variables
-   - If CI runs multiple test suites, run them all
-
-6. **ANALYZE THE FAILURE** - Use the log_index and excerpt to understand:
-   - What exactly failed (test name, file, assertion)
-   - 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
-   - Lint failures: fix code style issues
-   - Timeout/flaky tests: investigate race conditions or increase timeouts
-
-8. **VERIFY THE FIX** - Run the EXACT same CI command again to confirm the fix works
-
-9. **COMMIT AND PUSH** - Use \`${ghPullfrogMcpName}/git\` for add/commit, then \`${ghPullfrogMcpName}/push_branch\` to push

+   - 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. 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.
-   - ${dependencyInstallationStep}
-   - Use file operations to create/modify files with your changes.
-   - Test your changes to ensure they work correctly. Run relevant tests, builds, or linters BEFORE committing. If tests fail, fix the issues and repeat until everything passes.
-   - Commit your changes with \`${ghPullfrogMcpName}/git\` (\`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.
-   - Determine whether to create a PR:
-     - **Default behavior**: Create a PR using ${ghPullfrogMcpName}/create_pull_request with an informative title and body. If you are working in the context of an issue (check EVENT DATA for \`issue_number\` where \`is_pr\` is not true), include "Closes #<issue_number>" in the PR body to auto-close the issue when merged.
-     - **Branch-only request**: If the user explicitly asks for a branch without a PR (e.g. "don't create a PR", "branch only", "just create a branch"), do NOT create a PR. Simply push the branch and report the branch link.
+3. Finalize:
+   - if code changes were made, push to a pull request (new or existing) using \`${t("push_branch")}\` and \`${t("create_pull_request")}\` as needed. \`git status\` must be clean before you finish (see *SYSTEM* Git rules if push fails).
+   - call \`${t("report_progress")}\` once with results — include exact tool errors if push or PR creation failed
