RPI Commands (/research · /plan · /implement)
Command trio (/rpi/research, /rpi/plan, /rpi/implement) implementing the RPI pattern in .claude/commands/. The humanlayer/riptide-rpi repo itself is a HumanLayer Claude Code plugin for Linear tickets (version 0.2.0, December 2025): it ships only a setup skill and requires the humanlayer and linear CLIs. The three commands are therefore written in your own repo, with the repo as inspiration.
Strengths
- 3 .md files to write, zero dependencies
- Each phase = dedicated subagent with restricted tools (Research: read-only, Implement: write)
- 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
