# Task List Management
Guidelines for managing task lists in markdown files to track progress on completing a PRD
## Task Implementation
- **One sub-task at a time:** Do **NOT** start the next sub‑task until you ask the user for permission and they say "yes" or "y"
- **Completion protocol:**
1. When you finish a **sub‑task**, immediately mark it as completed by changing `[ ]` to `[x]`.
2. If **all** subtasks underneath a parent task are now `[x]`, follow this sequence:
- **First**: Run the full test suite (`pytest`, `npm test`, `bin/rails test`, etc.)
- **Only if all tests pass**: Stage changes (`git add .`)
- **Clean up**: Remove any temporary files and temporary code before committing
- **Commit**: Use a descriptive commit message that:
- Uses conventional commit format (`feat:`, `fix:`, `refactor:`, etc.)
- Summarizes what was accomplished in the parent task
- Lists key changes and additions
- References the task number and PRD context
- **Formats the message as a single-line command using `-m` flags**, e.g.:
```
git commit -m "feat: add payment validation logic" -m "- Validates card type and expiry" -m "- Adds unit tests for edge cases" -m "Related to T123 in PRD"
```
3. Once all the subtasks are marked completed and changes have been committed, mark the **parent task** as completed.
- Stop after each sub‑task and wait for the user's go‑ahead.
## Task List Maintenance
1. **Update the task list as you work:**
- Mark tasks and subtasks as completed (`[x]`) per the protocol above.
- Add new tasks as they emerge.
2. **Maintain the "Relevant Files" section:**
- List every file created or modified.
- Give each file a one‑line description of its purpose.
## AI Instructions
When working with task lists, the AI must:
1. Regularly update the task list file after finishing any significant work.
2. Follow the completion protocol:
- Mark each finished **sub‑task** `[x]`.
- Mark the **parent task** `[x]` once **all** its subtasks are `[x]`.
3. Add newly discovered tasks.
4. Keep "Relevant Files" accurate and up to date.
5. Before starting work, check which sub‑task is next.
6. After implementing a sub‑task, update the file and then pause for user approval.
