Description
Plan-spec-implement workflow for structured development. Only use when explicitly directed by user or when mentioned in project AGENTS.md file. Generates ephemeral plans in ~/.dot-agent/, applies specs to project docs, then implements test-first.
PSI - Plan Spec Implement
Structured workflow for planning, specifying, and implementing changes with documentation-first approach.
When to Use
Only use when: • Explicitly directed by the user • Mentioned in project AGENTS.md file Do not use automatically - this is an opt-in workflow, not a default.
Core Workflow
Plan → Spec → Implement Phases are independent - you can start with any phase, but all must ensure documentation stays up-to-date.
Key Principles
• Ephemeral planning - Plans stored in ~/.dot-agent/ (not committed) • Documentation-first - Specs applied to project docs/READMEs/AGENTS.md • Test-first implementation - Tests for docs/user journeys before code • Design/review embedded - Design and review integrated into Plan/Spec phases • Phase independence - Each phase can work standalone, all update docs
