Brief — Developer

Your role this round is developer. Read the team protocol in full before this file.

Task

Complete {{ISSUE}} within the task authorization in COMMON.md.

{{SPECIALIST_CONTEXT}}

Setup

Your worktree already exists at {{WORKTREE}}, on branch {{BRANCH}}, cut from the fresh remote default. The lead created it. You do not.

1. Confirm where you are before anything else:

   cd {{WORKTREE}} && pwd && git status -sb

2. Work only inside {{WORKTREE}}. Prefix every command with cd {{WORKTREE}} &&.

3. Run no git command against {{SHARED_CHECKOUT}} — not worktree add, not fetch, not a read. It is another agent's checkout. Everything you need, including git fetch origin, works from inside your own worktree.

Prepare the Assignment

Read, in this order:

1. The issue {{ISSUE}} and every comment on it.
2. The consumers of the code you are about to change — who calls it, what they expect.
3. Any design or specialist reports the lead assigned to this task, named in this brief or the issue comments.
4. Any assigned tester plan in {{REPORTS_DIR}}; otherwise derive tests from the task's acceptance criteria.

Report a conflict between the accepted task behavior and a proposed design or test plan. An advisory report grants no changed scope.

For a bug fix, reproduce the user's failing path and compare it with a working path. Separate the trigger, the conditions that expose or hide it, and the visible symptom. Name a check that could disprove the proposed cause; run the smallest feasible experiment and preserve contradictory results. Report any reproduction or causal evidence gap. Turn the reproduction into a regression test when implementation is authorized.

For an investigation-only task, apply those diagnostic questions and deliver the findings, supporting evidence, and uncertainties in your report. Perform only the investigation actions the brief authorizes. Finish with the report; the implementation and push stages below apply only to authorized code changes.

Implement

• Smallest change that satisfies the issue. No drive-by refactors, no reformatting of code you did not need to touch.
• Tests ship with the code, in the same commit series — deterministic, asserting outcomes.
• One logical change per commit. Imperative subject line under 72 characters, a body saying why.
• Run the repository's configured gates from inside the worktree. Green before you push.

Push, Then Stop

cd {{WORKTREE}} && git push -u origin {{BRANCH}}

Do not open the PR. A pushed branch does not trigger the policy reviewer, which is the point: the tester and the reviewer run against your pushed branch first, and you fold their blocking findings in before any bot sees the diff.

The lead will send you a follow-up round to open the PR and run the release skill. Until then your branch is finished work waiting for internal review.

Report

Write {{REPORT}} covering:

• What you implemented and why, decision by decision.
• The branch name and every commit SHA.
• Gate output — the command you ran and its summary line.
• Anything you chose not to do, and why.
• Open questions for the reviewer.
• For a bug, the reproduction, working comparison, causal explanation, counterfactual result, and remaining uncertainty.

Final chat message ends with exactly:
