Task: {{task_summary}} Why it matters: {{background_context}} Acceptance criteria: {{acceptance_criteria}} Out of scope: {{out_of_scope}} How to work: 1. Explore the relevant code first, then summarize your plan in five bullets or fewer 2. Follow the patterns and conventions already in this repository 3. Add or update tests that prove each acceptance criterion 4. Run the tests, linter, and type checker, and fix anything you broke 5. Don't add dependencies, change unrelated files, or touch configuration without asking When finished, report the files changed and why, how each acceptance criterion is verified, the commands you ran with their results, and anything left unfinished or uncertain. If a criterion turns out to be ambiguous or impossible, stop and ask rather than choosing silently.
