+ * Claude Code agent — secure harness around the `claude` CLI.
+ *
+ * mirrors the opentoad harness's security model:
+ * - native Bash blocked via --disallowedTools (agent cannot shell out)
+ * - 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.).
+ * security is enforced at the tool layer, not the process layer.

-  Build: `### Checklist
-
-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 \`${ghPullfrogMcpName}/report_progress\` with the final summary including PR link
-
-### Notes
-
-For simple, well-defined tasks, skip the plan phase and go straight to build.`,
-
-  ResolveConflicts: `### Checklist
-
-1. **Setup**:
-   - Call \`${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\`
-   - Call \`${ghPullfrogMcpName}/report_progress\` with a summary of what was resolved`,
-
-  AddressReviews: `### Checklist
-
-1. Checkout the PR branch via \`${ghPullfrogMcpName}/checkout_pr\`.
-
-2. Fetch review comments via \`${ghPullfrogMcpName}/get_review_comments\`.
-
-3. For each comment:
-   - understand the feedback
-   - make the code change using your native tools
-   - record what was done
-
-4. Quality check:
-   - test changes, then review the diff before committing — verify only intended changes are present, no debug artifacts remain, and the changes are clean enough that a senior engineer would approve without hesitation
-   - commit locally via shell (\`git add . && git commit -m "..."\`)
-
-5. Finalize:
-   - push changes via \`${ghPullfrogMcpName}/push_branch\`
-   - reply to each comment using \`${ghPullfrogMcpName}/reply_to_review_comment\`
-   - resolve addressed threads via \`${ghPullfrogMcpName}/resolve_review_thread\`

-
-  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 a **single** review:
-   - call \`${ghPullfrogMcpName}/create_pull_request_review\` with all comments and a unified summary body
-   - call \`${ghPullfrogMcpName}/report_progress\` with the summary
-   - if no actionable issues found, skip the review — just call \`report_progress\` noting the PR was reviewed`,
-
-  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 \`${ghPullfrogMcpName}/get_review_comments\` with the review ID to retrieve specific prior line-level feedback.
-
-4. For each area of the new changes:
-   - review the incremental diff while using the full diff for context
-   - check whether prior review feedback was addressed by the new commits
-   - trace data flow, check boundaries, verify assumptions, consider lifecycle, spot performance issues
-   - if the new commits remove, rename, or deprecate anything, run impact analysis with grep across code/tests/docs/comments/configs to find stale references and include those findings in the summary body
-   - never repeat prior feedback. if the author did not address an earlier comment, assume it was intentionally declined; only comment on genuinely new issues introduced by the new commits
-   - draft inline comments with NEW line numbers from the full PR diff — every comment must be actionable (2-3 sentences max)
-
-5. Self-critique: drop any comments that are praise, style preferences, speculative, about pre-existing code, or not actionable.
-
-6. Submit a **single** review:
-   - if actionable issues found: call \`${ghPullfrogMcpName}/create_pull_request_review\` with \`approved: false\`, all comments, and an **empty body** (do NOT include a summary — inline comments speak for themselves and a top-level comment clutters the PR conversation on every re-review)
-   - if no actionable issues found: submit with \`approved: true\` and an **empty body** (no inline comments, no summary)
-   - do NOT call \`${ghPullfrogMcpName}/report_progress\` — incremental reviews should be silent`,

-1. **CHECKOUT** - Determine whether to checkout the existing PR branch or create a new one:
-   - **PR event, modifying the existing PR**: Call \`${ghPullfrogMcpName}/checkout_pr\` with the PR number to checkout the PR branch.
-   - **PR event, but user wants a NEW branch/PR**: Create a new branch with \`git checkout -b pullfrog/branch-name\` via the \`${ghPullfrogMcpName}/git\` tool.
+1. **plan** (optional, for complex tasks): analyze requirements, read AGENTS.md and relevant code, produce a step-by-step implementation plan.
 
-   Branch names must be prefixed with "pullfrog/" and be specific enough to avoid collisions. Never commit directly to main/master/production.
+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\`)
 
-2. **DEPENDENCIES** - ${dependencyInstallationStep}
+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
 
-3. **CONTEXT** - If the request requires understanding the codebase structure or conventions, gather relevant context. Read AGENTS.md if it exists. Skip this step if the prompt is trivial and self-contained.
+4. **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 "..."\`)
 
-4. **REQUIREMENTS** - Understand the requirements and any existing plan.
+5. **finalize**:
+   - push the branch via \`${t("push_branch")}\`
+   - create a PR via \`${t("create_pull_request")}\`
+   - call \`${t("report_progress")}\` with the final summary including PR link
 
-5. **IMPLEMENT** - Make the necessary code changes using file operations. You should change the minimum amount of code necessary to accomplish your task. Emphasize code quality and elegance.
+${learningsStep(t, 6)}
 
-6. **TEST** - Test your changes to ensure they work correctly. Run relevant tests, builds, or linters BEFORE committing. If tests fail, fix the issues and repeat this step until everything passes.
+### Notes
 
-7. **COMMIT** - Commit your changes using \`${ghPullfrogMcpName}/git\` (e.g., \`git add .\` then \`git commit -m "message"\`), then push with \`${ghPullfrogMcpName}/push_branch\`. Do NOT use \`git push\` directly - it requires credentials that only the MCP tool provides.
-
-8. **PROGRESS** - ${reportProgressInstruction}
-
-9. **PR** - Determine whether to create a PR (if not already on a PR branch):
-   - **Default behavior**: Create a PR using ${ghPullfrogMcpName}/create_pull_request with an informative title and body. If you are working in the context of an issue (check EVENT DATA for \`issue_number\` where \`is_pr\` is not true), include "Closes #<issue_number>" in the PR body to auto-close the issue when merged.
-   - **Draft PR request**: If the user explicitly asks for a draft PR (e.g. "draft PR", "create as draft", "WIP"), create a PR with \`draft: true\`.
-   - **Branch-only request**: If the user explicitly asks for a branch without a PR (e.g. "don't create a PR", "branch only", "just create a branch"), do NOT create a PR. Simply push the branch and report the branch link.
-
-10. **FINAL REPORT** - Call report_progress one final time ONLY if you haven't already included all the important information (PR links, branch links, summary) in a previous report_progress call. If you already called report_progress with complete information including PR links after creating the PR, you do NOT need to call it again. Only make a final call if you need to add missing information. When making the final call, ensure it includes:
-   - A summary of what was accomplished
-   - Links to any artifacts created (PRs, branches, issues)
-   - If you created a PR, ALWAYS include the PR link. e.g.:
-     \`\`\`md
-     [View PR ➔](https://github.com/org/repo/pull/123)
-     \`\`\`
-   - If you created a branch without a PR, ALWAYS include a "Create PR" link and a link to the branch. e.g.:
-     \`\`\`md
-     [\`pullfrog/branch-name\`](https://github.com/pullfrog/scratch/tree/pullfrog/branch-name) • [Create PR ➔](https://github.com/pullfrog/scratch/compare/main...pullfrog/branch-name?quick_pull=1&title=<informative_title>&body=<informative_body>)
-     \`\`\`
-
-   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.

Keep replies extremely brief (1 sentence max, e.g., "Fixed by renaming to X" or "Added null check"). If suggesting a small, specific, self-contained code change, use GitHub's suggestion format with \`\`\`suggestion blocks. After addressing a comment and posting your reply, use ${ghPullfrogMcpName}/resolve_review_thread with the thread_id to mark it as resolved. Only resolve threads where you made code changes to address the feedback — don't resolve threads that are already resolved, threads where no action was taken, or threads where you disagree with the feedback.

-1. **CHECKOUT** - Call ${ghPullfrogMcpName}/checkout_pr with the PR number. This should give you all PR metadata you need, including a \`diffPath\`: a path to a temp file containing the PR diff.
+1. Checkout the PR via \`${t("checkout_pr")}\` — this returns PR metadata and a \`diffPath\`. Read the diff to identify the major areas of change.
 
-2. **ANALYZE** - Read the modified files to understand the changes in context.
-   - **Understand the change**: What is being modified and why? What's the before/after behavior?
-   - **Evaluate the approach**: Is it sound? If not, focus on approach before implementation details.
+2. 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)
+   - use GitHub permalink format for code references
+   - 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.
 
-3. **INVESTIGATE** - Actively hunt for problems. Use these techniques:
-   - **Trace data flow**: Use grep to follow how data moves through the system. How is state passed? Where could it get lost?
-   - **Check boundaries**: What happens across process boundaries, module boundaries, async boundaries? State that exists in one context may not exist in another.
-   - **Explore failure modes**: What if this throws? What if that returns null? What if the network fails? What if this runs twice?
-   - **Verify assumptions**: If the code assumes X, verify X is actually true. Use grep, read related files, check documentation.
-   - **Consider lifecycle**: Initialization, cleanup, error recovery. Are resources acquired before use? Released after? What happens on cancellation?
-   - **Spot performance issues**: Nested loops over large collections, blocking I/O, memory leaks, excessive object creation in hot paths, inefficient array operations (e.g., repeated \`.find()\` in a loop).
-   - **Check PR consistency**: Does the PR title/description match the actual code changes? Flag significant discrepancies.
-   - **Impact analysis**: Identify what was removed, renamed, or deprecated in the PR. Use grep to search the broader codebase for remaining references to those things in code, tests, docs, comments, and configs. Report stale references in the review body.
-   - 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** - Every comment must be actionable: the author should need to change something in response. 2-3 sentences max.

+   - use bullet lists, tables, and structured formatting liberally
+   - start with a 1-sentence TL;DR of what the new commits do
+   - then list the key changes (use a table for file-level changes if 3+ files changed, bullet list otherwise)
+   - note which prior review comments were addressed vs. not addressed (use a checklist: \`- [x] addressed\` / \`- [ ] not addressed\`)
+   - keep the entire summary compact — aim for ≤15 lines of markdown
+   - 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.

-   "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. **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. **DEPENDENCIES** - ${dependencyInstallationStep}
-
-5. **REPRODUCE LOCALLY** - Run the EXACT same command that CI runs:
-   - Do NOT simplify (e.g., don't run \`pnpm test\` if CI runs \`pnpm -r test --filter=action\`)
-   - Check if CI uses specific flags, filters, or environment variables
-   - If CI runs multiple test suites, run them all
-
-6. **ANALYZE THE FAILURE** - Use the log_index and excerpt to understand:
-   - What exactly failed (test name, file, assertion)
-   - Are there earlier warnings that might explain the failure?
-   - Is the failure flaky or deterministic?
-
-7. **FIX THE ISSUE** - Make the necessary code changes. Common patterns:
-   - Test assertion failures: fix the code or update the test expectation
-   - Build failures: fix type errors, missing imports, syntax issues
-   - Lint failures: fix code style issues
-   - Timeout/flaky tests: investigate race conditions or increase timeouts
-
-8. **VERIFY THE FIX** - Run the EXACT same CI command again to confirm the fix works
-
-9. **COMMIT AND PUSH** - Use \`${ghPullfrogMcpName}/git\` for add/commit, then \`${ghPullfrogMcpName}/push_branch\` to push
-
-10. **PROGRESS** - ${reportProgressInstruction}
-
-Your job is to fix issues THIS PR introduced, not to fix all CI failures. If in doubt about causation, abort and explain rather than making speculative changes.`,

+      prompt: `### Checklist
 
-1. **CHECKOUT** - Call ${ghPullfrogMcpName}/checkout_pr with the PR number. This fetches the PR branch.
+1. **Setup**:
+   - Call \`${t("checkout_pr")}\` to get the PR branch.
+   - Call \`${t("get_pull_request")}\` to identify the base branch (e.g., 'main').
+   - Call \`${t("git_fetch")}\` to fetch the base branch.
 
-2. **FETCH BASE** - Identify the base branch (usually main or master) and fetch it using ${ghPullfrogMcpName}/git_fetch (e.g., ref: "main").
+2. **Merge Attempt**:
+   - Run \`git merge origin/<base_branch>\` via shell.
+   - If it succeeds automatically, push via \`${t("push_branch")}\` and report success.
+   - If it fails (conflicts), resolve them manually.
 
-3. **ATTEMPT MERGE** - Use ${ghPullfrogMcpName}/shell to run \`git merge origin/<base_branch>\`.
-   - If the merge succeeds (exit code 0), the branch is up to date. Push it and you're done.
-   - If the merge fails, you have conflicts to resolve.
+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. **IDENTIFY CONFLICTS** - Run \`git status\` to see which files are conflicting (modified by both).
-
-5. **RESOLVE** - For each conflicting file:
-   - Read the file to see the conflict markers (\`<<<<<<<\`, \`=======\`, \`>>>>>>>\`).
-   - Determine the correct content. You may need to keep changes from both sides, or choose one.
-   - Edit the file to apply the resolution and remove the markers.
-
-6. **VERIFY** - ${dependencyInstallationStep}
-   - Run tests/builds to ensure the resolution is correct.
-
-7. **COMMIT** - Once all conflicts are resolved:
-   - \`git add .\`
-   - \`git commit -m "Merge branch <base_branch> into <pr_branch>"\` (or similar).
-
-8. **PUSH** - Call ${ghPullfrogMcpName}/push_branch.
-
-9. **PROGRESS** - ${reportProgressInstruction}
-`,
+4. **Finalize**:
+   - Run a final verification (build/test) to ensure the resolution works.
+   - \`git add . && git commit -m "resolve merge conflicts"\`

+   - Call \`${t("report_progress")}\` with a summary of what was resolved`,

-      prompt: `Follow these steps. THINK HARDER.
+      prompt: `### Checklist
 
-1. **UNDERSTAND** - Read the request carefully. Only take action if you have high confidence that you understand what is being asked. Take stock of the tools at your disposal.
+1. Analyze the task. For simple operations (labeling, commenting, answering questions, running a single command), handle directly.
 
-2. **CONTEXT** - If the request requires understanding the codebase structure or conventions, gather relevant context. Read AGENTS.md if it exists. Skip this step if the prompt is trivial and self-contained.
+2. For substantial work — code changes across multiple files, multi-step investigations:
+   - plan your approach before starting
+   - use native file and shell tools for local operations
+   - use ${pullfrogMcpName} MCP tools for GitHub/git operations
+   - 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. **EXECUTE** - Perform the requested task.
+3. Finalize:
+   - if code changes were made, push all changes to a pull request (new or existing). \`git status\` must be clean before you finish.
+   - call \`${t("report_progress")}\` with results
+   - if the task involved labeling, commenting, or other GitHub operations, perform those directly
 
-4. **CODE CHANGES** - If the task involves making code changes:
-   - Create a branch using \`${ghPullfrogMcpName}/git\` (\`git checkout -b pullfrog/branch-name\`). Branch names should be prefixed with "pullfrog/" and reflect the exact changes you are making. Never commit directly to main, master, or production.
-   - ${dependencyInstallationStep}
-   - Use file operations to create/modify files with your changes.
-   - Test your changes to ensure they work correctly. Run relevant tests, builds, or linters BEFORE committing. If tests fail, fix the issues and repeat until everything passes.
-   - Commit your changes with \`${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.
-     - **Draft PR request**: If the user explicitly asks for a draft PR (e.g. "draft PR", "create as draft", "WIP"), create a PR with \`draft: true\`.
-     - **Branch-only request**: If the user explicitly asks for a branch without a PR (e.g. "don't create a PR", "branch only", "just create a branch"), do NOT create a PR. Simply push the branch and report the branch link.
-
-5. **PROGRESS** - ${reportProgressInstruction}

 ### Git
 
-Use \`${ghPullfrogMcpName}/git\` for local git commands (status, log, diff, add, commit, checkout, branch, merge, etc.). For operations requiring remote authentication, use the dedicated MCP tools:
-- \`${ghPullfrogMcpName}/push_branch\` - push current or specified branch
-- \`${ghPullfrogMcpName}/git_fetch\` - fetch refs from remote
-- \`${ghPullfrogMcpName}/checkout_pr\` - checkout a PR branch (fetches and configures push for forks)
-- \`${ghPullfrogMcpName}/delete_branch\` - delete a remote branch (requires push: enabled)
-- \`${ghPullfrogMcpName}/push_tags\` - push tags (requires push: enabled)
+Use \`${t("git")}\` for local git commands (status, log, diff, add, commit, checkout, branch, merge, etc.). For operations requiring remote authentication, use the dedicated MCP tools:
+- \`${t("push_branch")}\` - push current or specified branch
+- \`${t("git_fetch")}\` - fetch refs from remote
+- \`${t("checkout_pr")}\` - checkout a PR branch (fetches and configures push for forks)
+- \`${t("delete_branch")}\` - delete a remote branch (requires push: enabled)
+- \`${t("push_tags")}\` - push tags (requires push: enabled)
 
 Rules:
+- All code changes must be pushed to a pull request (new or existing) before the run ends. This environment is ephemeral — unpushed work is lost permanently. \`git status\` must be clean when you finish.
 - Protected branches (default branch) are blocked from direct pushes in restricted mode. Do not use \`git push\` directly — it will fail without credentials.
-- Do not attempt to configure git credentials manually — the ${ghPullfrogMcpName} server handles all authentication internally.
+- Do not attempt to configure git credentials manually — the ${pullfrogMcpName} server handles all authentication internally.
 - Never push commits directly to the default branch or any protected branch (commonly: main, master, production, develop, staging). Always create a feature branch following the pattern: \`pullfrog/<issue-number>-<kebab-case-description>\` (e.g., \`pullfrog/123-fix-login-bug\`).
 - Never add co-author trailers (e.g., "Co-authored-by" or "Co-Authored-By") to commit messages.
 
 ### GitHub
 
-Use MCP tools from ${ghPullfrogMcpName} for all GitHub operations. Never use the \`gh\` CLI — it is not authenticated and will fail. The MCP tools handle authentication and enforce permissions.

 ### Progress reporting
 
-ALWAYS use \`report_progress\` to share your results and progress — never \`create_issue_comment\`. The \`report_progress\` tool updates the pre-created progress comment on the issue/PR. Using \`create_issue_comment\` instead creates duplicate comments and leaves the progress comment stuck in its initial state. The \`create_issue_comment\` tool is only for creating NEW standalone comments unrelated to your task progress.
+**Task list**: at the start of every run, create an internal task list based on the steps in your current mode. Update it as you complete each step. The system automatically renders this list to the progress comment — you do not need to call \`report_progress\` for this.
+
+**\`report_progress\`**: call this exactly once at the end of every run with a brief final summary (1-3 sentences) unless the mode guidance instructs otherwise. Never call it for intermediate status updates (e.g., "Checking for changes...", "Starting review...") — the task list handles live progress automatically. Calling \`report_progress\` replaces the task list with your summary and preserves the current task list in a collapsible section. Keep the summary concise — do not repeat what the task list already shows. Focus on the outcome (what was accomplished, links to artifacts) rather than listing individual steps.
+

+2. Post a comment via ${pullfrogMcpName} explaining what blocked you and what information or action would unblock you

+/**
+ * computes the incremental diff between two versions of a PR using range-diff
+ * on virtual squash commits created via `git commit-tree`.
+ *
+ * each PR version is squashed into a single synthetic commit (merge-base → tip tree),
+ * then range-diff compares those two single-commit ranges. this:
+ * - isolates each version's net effect (base branch noise eliminated via per-version merge bases)
+ * - avoids commit-matching issues that raw range-diff has with rebases/squashes/reordering
+ * - creates only loose git objects, no branches or refs (unlike temp-branch squash approaches)
+ *
+ * unlike fetchAndFormatPrDiff/formatFilesWithLineNumbers, this output has no line numbers.
+ * range-diff compares *patches* (diffs-of-diffs), not file trees — its hunk headers are
+ * `@@ file.ts` breadcrumbs, not positional `@@ -X,Y +A,B @@` markers. reconstructing
+ * line numbers would require cross-referencing with the v2 diff or content-matching against
+ * file trees, both of which are fragile (duplicate lines, hunk boundary shifts after rebase).
+ * a structured interdiff approach (diff two parsed patches, compare only +/- keys via Myers)
+ * could approximate line numbers but loses semantic precision: range-diff understands patch
+ * structure natively (rename detection, hunk-aware matching, dual-prefix inner/outer changes),
+ * while flat key-sequence comparison can misalign duplicate lines and can't distinguish
+ * "new addition to the PR" from "existing code newly modified by the PR". range-diff is the
+ * right abstraction here — the incremental diff answers "how did the changeset evolve?",
+ * not "where in the file is this?", and forcing positional line numbers onto it would be
+ * semantically misleading.
+ *
+ * alternatives considered:
+ * - plain git diff (two-tree or three-dot): includes base branch changes, no PR isolation
+ * - patch-text diffing (interdiff / diff-of-diffs): fragile, hunk offset noise on rebase
+ * - range-diff on raw commit ranges: confused by commit reorganization across force-pushes
