MyPowers Marketplace
A Claude Code plugin marketplace that ships the mypowers plugin — a six-skill complete development workflow for the design → plan → isolate → implement → finish loop.
MyPowers is distilled from the superpowers project and focuses on the development workflow skills that form a complete engineering loop.

Available Skills
Once installed, the following skills are available:
| Slash command | When to use |
|---|
/mypowers:brainstorming | Before creative work — explores intent, requirements, and design before implementation. |
/mypowers:writing-plans | When you have a spec or requirements for a multi-step task, before touching code. |
/mypowers:using-git-worktrees | Before implementation work when changes should be isolated from the current checkout. |
/mypowers:subagent-driven-development | When executing an implementation plan and subagents are available. |
/mypowers:executing-plans | When executing a written plan without subagents, or when inline execution is preferred. |
/mypowers:finishing-a-development-branch | After implementation is complete and verified, presents safe options to merge, PR, keep, or discard. |
The full workflow:
brainstorming → writing-plans → using-git-worktrees → subagent-driven-development OR executing-plans → finishing-a-development-branch
using-mypowers is not exposed as a callable skill. It lives in plugins/mypowers/docs/using-mypowers.md and is injected by the SessionStart hook as a lightweight introduction.
