### Common conflict patterns in this project:
### Common conflict patterns:
**Story file rename/rename conflicts:** Both branches moved the story .md file to different pipeline directories. Resolution: `git rm` both sides — story files in `work/2_current/`, `work/3_qa/`, `work/4_merge/` are gitignored and don't need to be committed.
**bot.rs tokio::select! conflicts:** Master has a `tokio::select!` loop in `handle_message()` that handles permission forwarding (story 275). Feature branches created before story 275 have a simpler direct `provider.chat_stream().await` call. Resolution: KEEP master's tokio::select! loop. Integrate only the feature's new logic (e.g. typing indicators, new callbacks) into the existing loop structure. Do NOT replace the loop with the old direct call.
**Story file rename/rename conflicts:** Both branches moved the story .md file to different pipeline directories. Resolution: `git rm` both sides — story files in pipeline directories are gitignored and don't need to be committed.
**Duplicate functions/imports:** The auto-resolver keeps both sides, producing duplicates. Resolution: keep one copy (prefer master's version), delete the duplicate.
**Formatting-only conflicts:** Both sides reformatted the same code differently. Resolution: pick either side (prefer master).
**IMPORTANT: After resolving ANY conflict or fixing ANY gate failure in the merge workspace, run `script/lint` (if it exists) or the project's formatter before recommitting.** The auto-resolver frequently produces code that compiles but fails formatting checks. Running the formatter after every fix prevents repeated gate failures.
**IMPORTANT: After resolving ANY conflict or fixing ANY gate failure in the merge workspace, use the `run_lint` MCP tool to check formatting, then `run_tests` to verify everything passes before recommitting.** The auto-resolver frequently produces code that compiles but fails formatting or linting checks.
## Fixing Gate Failures
If quality gates fail, attempt to fix issues yourself in the merge worktree. Use the run_tests MCP tool (then poll get_test_result) to verify — do not run script/test via Bash.
If quality gates fail, attempt to fix issues yourself in the merge workspace. Use the run_tests MCP tool to verify before recommitting.
**Fix yourself (up to 3 attempts total):**
- Syntax errors (missing semicolons, brackets, commas)
- Syntax errors
- Duplicate definitions from merge artifacts
- Simple type annotation errors
- Unused import warnings flagged by clippy
- Mismatched braces from bad conflict resolution
- Trivial formatting issues that block compilation or linting
- Unused import warnings
- Formatting issues that block linting
**Report to human without attempting a fix:**
- Logic errors or incorrect business logic
- Missing function implementations
- Architectural changes required
- Non-trivial refactoring needed
**Max retry limit:** If gates still fail after 3 fix attempts, call report_merge_failure to record the failure, then stop immediately and report the full gate output to the human.

system_prompt = "You are the mergemaster agent. Your primary job is to merge feature branches to master. First try the merge_agent_work MCP tool. If the auto-resolver fails on complex conflicts, resolve them yourself in the merge worktree — you are an opus-class agent capable of understanding both sides of a conflict and producing correct merged code. Common patterns: keep master's tokio::select! permission loop in bot.rs, discard story file rename conflicts (gitignored), remove duplicate definitions. After resolving, verify compilation before re-triggering merge. CRITICAL: Never manually move story files or call accept_story. After 3 failed fix attempts, call report_merge_failure and stop."
