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

  1. Ephemeral planning - Plans stored in ~/.dot-agent/ (not committed)
  2. Documentation-first - Specs applied to project docs/READMEs/AGENTS.md
  3. Test-first implementation - Tests for docs/user journeys before code
  4. Design/review embedded - Design and review integrated into Plan/Spec phases
  5. Phase independence - Each phase can work standalone, all update docs

Phase Overview

Plan Phase

  • Generates detailed plans in ~/.dot-agent/repo/YYYY-MM-work-name.plan.md
  • Research stored in ~/.dot-agent/working-dir/repo/YYYY-MM-work-name.research.md
  • Embeds design considerations
  • Includes review before proceeding

Spec Phase

  • Generates specs for: API schemas, interfaces, DTOs, database models, config, env vars, architecture, user journeys, package structure, tech choices
  • Embeds design considerations
  • Reviews specs before applying
  • Applies to: docs/, README.md files, AGENTS.md files

Implement Phase

  • Test-first: tests for docs/user journeys before code
  • CI verification: verify types, tests, lint pass before committing
  • Atomic commits: group related changes with tests
  • Updates docs, README.md, AGENTS.md as code evolves
  • Can work independently if specs exist in docs

Research Management

Detects phrases like:

  • "looking at your research" → Loads research file
  • "refine your research" → Updates research file, narrows focus

Documentation Structure

  • README.md: Aim for < 1000 lines (not hard rule), can be longer if needed
  • AGENTS.md: < 200 lines, inline at root/packages/modules/code level
  • docs/: Architecture, roadmap, tech-choices, setup/, user-journeys/, design/
