ed3d-plugins
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 sysadmin—these 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.
Using ed3d-plan-and-execute
More in the README for the plugin, and it's worth skimming, but here's a quickstart:
Rough Idea
│
▼
/start-design-plan ──────► Design Document (committed to git)
│
▼
/start-implementation-plan ──► Implementation Plan (phase files)
│
▼
/execute-implementation-plan ──► Working Code (reviewed & committed)
Customization: Create .ed3d/design-plan-guidance.md and .ed3d/implementation-plan-guidance.md in your project to provide project-specific constraints, terminology, and standards. Run /how-to-customize for details.

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!)
