RPI Commands (/research · /plan · /implement)
Command trio implementing the RPI pattern in .claude/commands/: /rpi/research (explores the codebase, collects context), /rpi/plan (writes spec before touching code), /rpi/implement (executes against the plan). Each command forks a dedicated subagent, fresh context, single responsibility.
Strengths
- 3 .md files, 30-second install, zero dependencies
- Each phase = dedicated subagent with restricted tools (Research: read-only, Implement: write)
- Reference implementation of the pattern adopted by GSD, BMAD, Superpowers
Limitations
- No state machine or cross-session persistence, each /implement starts fresh
- Less powerful than GSD or Superpowers for long multi-session projects
Best for
- Devs adopting Claude Code who want the RPI pattern without installing a full framework
- Isolated tasks on an existing codebase, quick Claude context onboarding
