polish CLI init UX, backfill jobId on workflow-run page, bump to 0.0.195

simplify installation-not-found flow by removing ownerHasInstallation
field and collapsing the "selected repos" vs "no access" branches into
a single message with a confirm prompt. improve spinner/log copy
throughout init (secrets, model, workflow, test run).

backfill missing jobId on workflow-run redirect page by querying the
GitHub API for the pullfrog job when jobId is null. add 600ms delay
in handleWorkflowRunInProgress before fetching jobs to avoid racing
the job assignment.

+ * 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.

-  Build: `### Checklist
-
-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

-  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": "..." }, ...] }\`

-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...".

+1. Use \`previousSummaryBody\` from this response as the current summary to revise.
+2. Checkout the PR via \`${t("checkout_pr")}\` — this returns PR metadata and a \`diffPath\`.
+3. Read the diff using the TOC to selectively read relevant sections. Produce an updated summary reflecting the current state of the PR, using the existing summary (\`previousSummaryBody\`) as a starting point. If EVENT INSTRUCTIONS specify a custom format, follow that instead of the default format below.
+4. Call \`${t("edit_issue_comment")}\` with \`commentId: existingSummaryCommentId\` (from this response) and the updated summary body.
+5. Call \`${t("report_progress")}\` with a brief note (e.g., "Updated PR summary.").
 
-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.`,

-- **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\`.

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
+- Get the file count and commit count from the checkout_pr metadata, not by counting manually`;

-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**:
+   - 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
 
-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.
-   - 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.

+   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.

-   - 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}

+      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 ${ghPullfrogMcpName}/git_fetch (e.g., ref: "main").
+2. **Merge Attempt**:
+   - Run \`git merge origin/<base_branch>\` via shell.
+   - If it succeeds automatically, confirm a clean working tree, push via \`${t("push_branch")}\` (same push/prepush guidance as Build mode in *SYSTEM*), and call \`${t("report_progress")}\` with a brief success note or the exact push error if push failed — **then stop; do not run steps 3–4.**
+   - If it fails (conflicts), resolve them manually (continue to steps 3–4).
 
-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** - ${reportProgressInstruction}
-`,
+4. **Finalize**:
+   - Run a final verification (build/test) to ensure the resolution works.
+   - \`git add . && git commit -m "resolve merge conflicts"\`
+   - confirm a clean working tree, then push via \`${t("push_branch")}\` (same push/prepush guidance as Build mode in *SYSTEM*)
+   - Call \`${t("report_progress")}\` with a summary of what was resolved (or the exact push error if push failed)`,

-      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 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
+   - 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.
