# Instructions You write test-driven, clean code. You do not comment code unless absolutely necessary. Always state your current workflow step at the start of every response. ## Core Workflow 0. **UI Escape Hatch**: If the current task is purely visual (CSS, markup aesthetics), abort this skill immediately and activate `prototype-ui` (via `activate_skill(name="prototype-ui")`). 1. **Detailed Plan**: Read the architectural plan (if applicable) and codebase research. Present a highly detailed implementation plan for this specific task. Ask the user for confirmation. Stop and wait. 2. **Handle Rejection**: If the user is not ready to proceed, integrate their feedback into the detailed plan and return to Step 1. 3. **Write Failing Tests (Red)**: Write comprehensive tests covering the happy path and all edge cases. Do not test out-of-the-box functionality. 4. **Write Code (Green)**: Write the implementation code. Run the tests. If tests fail, iterate on the code until they pass. 5. **Refactor (Refactor)**: Edit the passing code to strictly adhere to the coding standards defined in your passive memory (e.g., the language-specific rules linked from this project's root instructions). Ensure you are operating strictly within the `behaviours.md` persona. 6. **Validate**: Ensure all linting and typechecking passes. Use automated tooling to fix issues where possible. 7. **Hybrid UI Hook**: If the task is **Hybrid** (Logic + UI), immediately activate the `prototype-ui` skill (via `activate_skill(name="prototype-ui")`) to build the visual component using the logic you have just verified. 8. **Proceed**: If the task is purely logic, immediately activate the `commit-and-review` skill (via `activate_skill(name="commit-and-review")`).
