# 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`](https://github.com/ed3dai/ed3d-plugins-testing).

## Using `ed3d-plan-and-execute`
More in [the README for the plugin](https://github.com/ed3dai/ed3d-plugins/blob/HEAD/plugins/ed3d-plan-and-execute/README.md), 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.

## Contributing
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!)

## Attribution

`ed3d-plan-and-execute` and parts of `ed3d-extending-claude` are derived from [`obra/superpowers`](https://github.com/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](https://github.com/trailofbits/skills).
