# registry-search

Finds reusable registry modules and component packages for a board or specification. It prevents duplicate work before authoring hardware designs.

## What it does

The skill queries the registry to locate existing hardware packages before you build new ones. It follows a strict priority order: first matching reusable modules, then components with support circuitry, and primitives last. To inspect public APIs, it runs `pcb list -m -json <module-url>@<version>` to read candidate source files. Inferring IO or config parameters directly from search results is prohibited.

Selected `.zen` entrypoints are instantiated with `Module()`, managing dependencies through `zener-language`. Editing `pcb.toml` by hand is not allowed. The skill also avoids cloning other boards unless you explicitly request it, and any requested clones stay outside the working repository.

If a package is missing or broken, board workflows must prepare a `librarian-dispatch` request or run `librarian` in a registry checkout.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add diodeinc/pcb --skill registry-search -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/registry-search/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/registry-search/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add diodeinc/pcb --skill registry-search -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/registry-search/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add diodeinc/pcb --skill registry-search -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/registry-search/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install diodeinc/pcb registry-search
```

2. **Manually: put the files in place**
- File: `.github/skills/registry-search/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add diodeinc/pcb --skill registry-search -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/diodeinc/pcb --path skills/registry-search
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/registry-search/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add diodeinc/pcb --skill registry-search -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/diodeinc/pcb/tree/HEAD/skills/registry-search/SKILL.md

## When to use it
- search the registry for reusable modules and component packages
- inspect module APIs via `pcb list` without guessing IO names
- instantiate `.zen` entrypoints with `Module()` correctly
- create `librarian-dispatch` requests when matching packages are missing

## Example prompts
- Search the pcb registry for a power management module matching our spec
- Inspect the candidate module API with pcb list and instantiate its .zen entrypoint

# Registry Search

Search the registry before authoring a new reusable package. Read a
candidate's source (`pcb list -m -json <module-url>@<version>` reports its
`dir`) for its public API; do not infer IO or config names from a search result.

Prefer a reusable module that matches the need, then a component with its
support circuitry, then a primitive. Instantiate the chosen `.zen` entrypoint
with `Module()` and follow `zener-language` for dependencies; do not hand-edit
`pcb.toml`.

Discover or clone other boards only when the user explicitly asks, and clone
them outside the current checkout.

If no suitable package exists or one needs a fix, use `librarian` in a registry
checkout; from board work, prepare a `librarian-dispatch` request.
```
