Quick Start

Follow this process:

1. Phase 0: Clarify requirements (ask up to 5 targeted questions)
2. Phase 1: Research & understand the codebase
3. Phase 2: Create detailed plan with sprints, tasks, acceptance criteria
4. Phase 3: Subagent review of the plan
5. Phase 4: Return the plan in markdown and save a file only if the user asked for a persisted artifact

Key Principles

Task Atomicity

Each task must be:

• Atomic and committable — small, independent pieces of work
• Specific and actionable — not vague
• Testable — include tests or validation method
• Located — include file paths and code locations

Bad vs Good Task Breakdown

❌ Bad: "Implement third-party sign-in"

✓ Good:

• "Add sign-in config to environment variables"
• "Install and configure the required authentication package"
• "Create sign-in callback route handler in src/routes/auth.ts"
• "Add the sign-in button to the login UI"
