Worktree Agent Rules

Mandatory rules for any agent dispatched with isolation: "worktree".

Rule 1: Verify Your Working Directory

On start, run pwd. Your path MUST contain .claude/worktrees/. If your CWD is the main repo path, STOP and report the error.

Rule 2: Create Feature Branch First

git checkout -b <branch-name>

Never commit on the default worktree-agent-* branch. Create your feature branch FIRST.

Rule 3: Use Worktree-Relative Paths

Never hardcode absolute paths from the main repo. Use $(git rev-parse --show-toplevel)/path. Exception: Reading gitignored ADR files requires the main repo absolute path.

Rule 4: Ignore Auto-Plan Hooks

Keep planning inline instead of creating task_plan.md. If the auto-plan hook fires, continue with the current task and keep your attention on implementation.

Rule 5: Stage Specific Files Only

git add path/to/specific/file.py

Never git add ., git add -A, or git add --all. Verify with git diff --cached --stat.

Rule 6: Do Not Touch the Main Worktree

Never write to paths outside your worktree directory. Never run git checkout in the main repo.

Rule 7: Commit with Conventional Format

Use the commit message specified in your prompt. No attribution lines.

Rule 8: Run Both ruff Checks Before Declaring CI-Ready

For any Python code changes, run both checks before pushing or creating a PR:

ruff check . --config pyproject.toml
ruff format --check . --config pyproject.toml

Running only ruff check misses formatting violations. The Tests / lint CI job runs both — if you skip ruff format --check, the PR will fail CI and cannot merge due to branch protection.

Failure Modes This Prevents

| Failure | Rule | Without It | |---------|------|-----------| | Agent edits main repo files | 1, 6 | Changes leak to main, get stashed/lost | | Context wasted on task_plan.md | 4 | Implementation budget consumed by planning | | Commit on wrong branch | 2 | Orchestrator merges wrong content | | PR has changes from 2 ADRs | 5, 6 | Cross-contamination between agents | | Branch locked by worktree | 2 | Fatal error on checkout | | PR fails CI on format | 8 | Merge blocked; ruff format --check was skipped |
