This is my collection of plugins that I use on a day-to-day basis for getting stuff done with Claude Code. Most of these are development-oriented in some way or another, but also often end up being useful for other things. Product design, general research, accidentally becoming my homelab sysadminβthese are a lot of what I've learned so far and what I've found helpful.
The big stick in this repository is ed3d-plan-and-execute, which implements an "RPI" (research-plan-implement) loop that I think does a really good job of avoiding hallucination in the planning stages, adhering to high-level product requirements, avoiding drift between design planning and implementation planning, and reviewing the results such that you get out the other end not just what you asked for, but what you actually wanted.
NOTE: ed3d-plugins is generally a more stable marketplace. If you'd like to track changes as they happen a bit more aggressively, take a look at ed3d-plugins-testing.

Issues and pull requests gratefully solicited, except ed3d-house-style is my house style, and provided for reference, so I might not take contributions there. (You can make your own house-style plugin though and use that instead!)
ed3d-plan-and-execute and parts of ed3d-extending-claude are derived from obra/superpowers by Jesse Vincent. The original plugin has been folded, spindled, and mutilated extensively.
Some skills in ed3d-house-style are derived from obra/superpowers and others (property-based-testing is a big one) are derived from the Trail of Bits Skills repository.
