When to use

• Implementing a single task from a plan
• Executing a clear, scoped behavioral change
• Delivering one focused vertical slice

Process

1. Read the task, spec, and relevant code before editing.
2. If the scope is vague or too large for one pass, stop and clarify or break it down.
3. Work in the repo's normal git context.
4. Implement the smallest useful slice that satisfies the task.
5. Add tests when behavior changes, bugs are fixed, or interfaces change.
6. Run the strongest project checks available: the full test suite when practical, plus any task-specific verification.

Verification

• The behavior matches the task or request
• New or changed behavior is covered by tests where it matters
• Tests pass
• Task-specific verification passes
• No unrelated scope was added

Rules

• One task at a time.
• Make the smallest safe change that fully solves the task.
• Preserve contracts unless the task explicitly changes them. If a contract must change, call it out clearly.
• Handle failure paths explicitly instead of leaving them implicit.
• If the request is vague, oversized, or mixes multiple tasks, stop and clarify or break it down.
• Do not hide missing verification. If you could not run something important, say so.
• Do not use this skill as an excuse for unrelated refactors.
