# reskill Usage Guide

reskill is a Git-based package manager for AI agent skills. It provides declarative configuration (`skills.json` + `skills.lock`), flexible versioning, and multi-agent support for installing, managing, and sharing skills across projects and teams.

## Security & Trust

This skill instructs the agent to run CLI commands via [reskill](https://github.com/nicepkg/reskill), an open-source, Git-based package manager for AI agent skills.

**Why a specific registry?**
reskill supports multiple registries. This skill defaults to the Rush community registry (`https://rush.zhenguanyu.com/`) — the primary public registry for the reskill ecosystem, similar to how npm defaults to `https://registry.npmjs.org`. Users can override it at any time via `--registry`, the `RESKILL_REGISTRY` environment variable, or `defaults.publishRegistry` in `skills.json`.

**CLI execution approach:**
To avoid downloading remote code on every invocation, we recommend installing reskill globally first:

```bash
npm install -g reskill
```

If a global installation is not available, `npx reskill@latest` can be used as a fallback. The agent should check for a global install (`which reskill`) before falling back to npx.

**Requirements:** Node.js >= 18.0.0

**Registry resolution** (highest to lowest priority):

1. `--registry <url>` CLI option
2. `RESKILL_REGISTRY` environment variable
3. `defaults.publishRegistry` in `skills.json`
4. Default: `https://rush.zhenguanyu.com/`

## When to Use This Skill

Use this skill when the user:

- Wants to install, update, or manage AI agent skills
- Mentions `skills.json`, `skills.lock`, or reskill-related concepts
- Wants to publish a skill to a registry
- Asks about supported install formats (GitHub, GitLab, HTTP, OSS, registry, etc.)
- Encounters reskill-related errors or needs troubleshooting
- Wants to set up a project for skill management
- Asks about multi-agent skill installation (Cursor, Claude Code, Codex, etc.)

## Quick Start

```bash
# Initialize a new project
reskill init

# Install a skill
reskill install github:anthropics/skills/skills/frontend-design@latest

# List installed skills
reskill list
```

| (none) | -                 | Default branch (main)              |

## Configuration

### skills.json

The project configuration file, created by `reskill init`:

```json
{
  "skills": {
    "planning": "github:user/planning-skill@v1.0.0",
    "internal-tool": "internal:team/tool@latest"
  },
  "registries": {
    "internal": "https://gitlab.company.com"
  },
  "defaults": {
    "installDir": ".skills",
    "targetAgents": ["cursor", "claude-code"],
    "installMode": "symlink"
  }
}
```

- `skills` — Installed skill references (name → source ref)
- `registries` — Custom Git registry aliases
- `defaults.installDir` — Where skills are stored (default: `.skills`)
- `defaults.targetAgents` — Default agents to install to
- `defaults.installMode` — `symlink` (default, recommended) or `copy`

### Environment Variables

| Variable            | Description                                     | Default                        |
| ------------------- | ----------------------------------------------- | ------------------------------ |
| `RESKILL_CACHE_DIR` | Global cache directory                          | `~/.reskill-cache`             |
| `RESKILL_TOKEN`     | Auth token (takes precedence over ~/.reskillrc) | -                              |
| `RESKILL_REGISTRY`  | Default registry URL                            | `https://rush.zhenguanyu.com`  |
| `DEBUG`             | Enable debug logging                            | -                              |
| `NO_COLOR`          | Disable colored output                          | -                              |

## Multi-Agent Support

Skills are installed to `.skills/` by default and can be integrated with any agent:

| Agent          | Path                                  |
| -------------- | ------------------------------------- |
| Cursor         | `.cursor/rules/` or `.cursor/skills/` |
| Claude Code    | `.claude/skills/`                     |
| Codex          | `.codex/skills/`                      |
| Windsurf       | `.windsurf/skills/`                   |
| GitHub Copilot | `.github/skills/`                     |
| OpenCode       | `.opencode/skills/`                   |

Use `--agent` to target specific agents, or `--all` to install to all detected agents:

```bash
# Install to specific agents
reskill install github:user/skill -a cursor claude-code

# Install to all detected agents
reskill install github:user/skill --all
```

## Publishing

### Authentication

```bash
# Login with a token (obtain from the registry web UI)
reskill login --registry https://rush.zhenguanyu.com --token <token>

# Check current login status
reskill whoami

# Logout
reskill logout
```

Tokens are stored in `~/.reskillrc`. You can also use the `RESKILL_TOKEN` environment variable (takes precedence, useful for CI/CD).

### Publishing a Skill

```bash
# Validate without publishing (recommended first step)
reskill publish --dry-run --registry https://rush.zhenguanyu.com

# Publish the skill
reskill publish --registry https://rush.zhenguanyu.com

# Publish from a specific directory
reskill publish ./path/to/skill --registry https://rush.zhenguanyu.com

# Skip confirmation
reskill publish -y --registry https://rush.zhenguanyu.com
```

The skill directory must contain a valid `SKILL.md`. A `skill.json` with `name`, `version`, and `description` is also required for publishing.

## Common Workflows

### First-Time Project Setup

```bash
# 1. Initialize the project
reskill init -y

# 2. Install skills your project needs
reskill install github:user/skill1@v1.0.0 github:user/skill2@latest -y

# 3. Verify installation
reskill list

# 4. Commit skills.json and skills.lock to version control
# (These files ensure team members get the same skill versions)
```

### Team Collaboration

When a teammate clones the project, they run:

```bash
# Reinstall all skills from skills.json (like npm install)
reskill install
```

This reads `skills.json` + `skills.lock` and installs the exact same versions.

### Checking and Updating Skills

```bash
# Check which skills have newer versions
reskill outdated

# Update all skills
reskill update

# Update a specific skill
reskill update skill-name
```

### Global vs Project-Level Installation

| Scope   | Flag | Directory               | Use Case                                   |
| ------- | ---- | ----------------------- | ------------------------------------------ |
| Project | -    | `.skills/` (in project) | Team-shared skills, committed to git       |
| Global  | `-g` | `~/.agents/skills/`     | Personal skills, available in all projects |

```bash
# Project-level (default)
reskill install github:user/skill

# Global (personal, all projects)
reskill install github:user/skill -g

# Personal project-level (not saved to skills.json)
reskill install github:user/skill --no-save
```

### Diagnosing Issues

```bash
# Run environment diagnostics
reskill doctor

# JSON output for programmatic use
reskill doctor --json
```

The `doctor` command checks: reskill version, Node.js version, Git availability, cache directory, `skills.json` validity, `skills.lock` sync, installed skills integrity, and network connectivity.

## Troubleshooting

| Error Message                        | Cause                                 | Solution                                                 |
| ------------------------------------ | ------------------------------------- | -------------------------------------------------------- |
| `skills.json not found`              | Project not initialized               | Run `reskill init`                                       |
| `Unknown scope @xyz`                 | No registry configured for this scope | Check `registries` in `skills.json` or use full Git URL  |
| `Skill not found`                    | Skill name doesn't exist in registry  | Verify skill name; check `reskill find <query>`          |
| `Version not found`                  | Requested version doesn't exist       | Run `reskill info <skill>` to see available versions     |
| `Permission denied`                  | Auth issue when publishing            | Run `reskill login`; check token scope                   |
| `Token is invalid or expired`        | Stale authentication                  | Re-authenticate with `reskill login --token <new-token>` |
| `Network error`                      | Cannot reach Git host or registry     | Check network; run `reskill doctor` for diagnostics      |
| `Conflict: directory already exists` | Skill already installed               | Use `--force` to reinstall                               |

### Private Repositories

reskill uses your existing git credentials (SSH keys or credential helper). For CI/CD environments:

```bash
# GitLab CI
git config --global url."https://gitlab-ci-token:${CI_JOB_TOKEN}@gitlab.company.com/".insteadOf "https://gitlab.company.com/"
```
