Build from the confirmed plan, one phase at a time.
Before Starting
- A confirmed plan must exist (from requirement-understanding)
- Read the plan — understand all phases before starting the first one
- Read project standards (AGENTS.md or similar) for coding conventions, commit format, and quality requirements
- Mark the current phase as active/in-progress in the plan before starting
For Each Phase
1. Research
- Read the plan's phase description (What / Files / Verify)
- Review existing code patterns and conventions in the project
- Read project coding standards and best practices (AGENTS.md)
- Load any skills relevant to this phase's work
- Check official docs via context7 for libraries being used
- Understand before writing — don't guess APIs, look them up
2. Implement
- Follow existing project patterns and conventions
- Follow project coding standards (AGENTS.md)
