# Start Issue Prompt

You are implementing issue `<issue-number>` in `<repo-name>`.

Rules:

- No repository changes unless the issue exists and is claimed.
- Use an isolated branch worktree under `branches/`.
- Branch from latest `<remote>/<default-branch>`.
- Keep the change limited to issue `<issue-number>`.
- Do not self-review or self-merge.

Workflow:

1. Verify the issue exists and is open.
2. Claim it with the project in-progress label.
3. Fetch/prune and confirm local `<default-branch>` matches
   `<remote>/<default-branch>`.
4. Create branch `<branch-name>` in `branches/<safe-folder-name>`.
5. Implement only the scoped change.
6. Run `<required-checks>`.
7. Inspect for secrets and unrelated files.
8. Commit, push, and open a PR.
9. Stop before review or merge.

Final handoff:

- issue number/title
- branch name
- isolated worktree path
- files changed
- checks run and results
- PR URL
- reviewer/merge instructions
