## What it does

This skill adds embedded Rust constraints to the agent context: no heap, static buffers, peripheral ownership, and interrupt-safe shared state. It steers code away from `Vec` towards `heapless::Vec<T, N>`, and points to critical sections with `Mutex<RefCell<T>>` where state is shared.

It watches `Cargo.toml` and `.cargo/config.toml`, including the target configuration. The guidance covers PAC and HAL layers, `embedded-hal`, RTIC, Embassy, plus patterns based on `#![no_std]`, `#![no_main]`, `#[entry]`, and static state.

Blocking code does not belong in an ISR because it can delay other interrupts. That is a reason to inspect interrupt handlers before adding I/O work.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add actionbook/rust-skills --skill domain-embedded -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add actionbook/rust-skills --skill domain-embedded -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add actionbook/rust-skills --skill domain-embedded -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install actionbook/rust-skills domain-embedded
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add actionbook/rust-skills --skill domain-embedded -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/actionbook/rust-skills --path skills/domain-embedded
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add actionbook/rust-skills --skill domain-embedded -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/actionbook/rust-skills/tree/HEAD/skills/domain-embedded/SKILL.md

## When to use it
- replace heap-backed collections in no_std code
- protect shared state from ISR races
- assign clear ownership to GPIO and peripherals
- choose RTIC, Embassy, or bare metal execution patterns

## Example prompts
- Review this `Cargo.toml` for embedded no_std Rust constraints.
- Replace this `Vec` buffer with a fixed `heapless` collection.
- Check GPIO access shared by an interrupt handler and the main loop.
