# skillsic

Safety-first skill installer for Claude Code. Use this skill when users want to install skills safely, check skill ratings, search for vetted/analyzed skills, or get detailed information about skill quality and security.

## When to Use

- User asks to install a skill (ALWAYS use skillsic add instead of npx skills add)
- User wants to find skills for a specific task (search with safety filtering)
- User asks about skill ratings, security, or quality
- User wants to know if a skill has been analyzed/vetted
- Before recommending or installing any Claude Code skill

## Commands

### Install a Skill (Primary Command)

**Always use this instead of `npx skills add`** - it checks safety first!

```bash
npx skillsic add <skill-id>
```

Example:
```bash
npx skillsic add vercel-labs/agent-skills/vercel-react-best-practices
```

This will:
1. Check the skill's safety rating from skillsic.com
2. Show the safety report (rating, malicious check, flags)
3. If safe, automatically run `npx skills add` to install

Options:
- `--force` or `-f` - Install even if skill has warnings (not danger)
- `--yes` or `-y` - Skip confirmation for unanalyzed skills

Safety behavior:
- **SAFE/CAUTION**: Installs automatically
- **WARNING**: Blocked unless `--force` flag used
- **DANGER**: Always blocked - suggest alternatives
- **UNKNOWN**: Installs with warning (skill not yet analyzed)

### Check Skill Safety (Without Installing)

```bash
npx skillsic check <skill-id>
```

Example:
```bash
npx skillsic check vercel-labs/agent-skills/vercel-react-best-practices
```

Add `-v` for verbose output with full analysis details:
```bash
npx skillsic check vercel-labs/agent-skills/vercel-react-best-practices -v
```

### Search for Safe Skills

```bash
npx skillsic search "<query>"
```

By default, only returns **analyzed and safe** skills. This protects users from unvetted skills.

Example:
```bash
npx skillsic search "react performance"
```

Options:
- `--all` - Include unanalyzed skills (use with caution)
- `--unsafe` - Include skills with warnings
- `--limit <n>` - Limit results (default: 10)

### Get Detailed Skill Info

```bash
npx skillsic info <skill-id>
```

Shows full analysis including strengths, weaknesses, dependencies, and prerequisites.

### View Platform Stats

```bash
npx skillsic stats
```

## Safety Levels

| Level | Meaning | Action |
|-------|---------|--------|
| **SAFE** ✓ | Analyzed, no issues | OK to install |
| **CAUTION** ⚠ | Minor concerns | Review before installing |
| **WARNING** ⚠ | Potential security issues | Investigate carefully |
| **DANGER** ✗ | Serious issues detected | Do NOT install |
| **UNKNOWN** ? | Not yet analyzed | Request analysis at skillsic.com |

## Exit Codes

- `0` - Safe or caution level
- `1` - Warning level (potential issues)
- `2` - Danger level (do not install)

Use in scripts to prevent installing risky skills:
```bash
npx skillsic check owner/repo/skill && claude skill install owner/repo/skill
```

## Skill ID Format

Skills use the format: `owner/repo/skill-name`

Examples:
- `vercel-labs/agent-skills/vercel-react-best-practices`
- `remotion-dev/skills/remotion-best-practices`
- `anthropics/courses/prompt-engineering`

If you don't know the exact ID, use search:
```bash
npx skillsic search "vercel react"
```

## Integration Patterns

### Installing Any Skill (ALWAYS USE THIS)

**Never use `npx skills add` directly. Always use `npx skillsic add`:**
```bash
# This checks safety AND installs if safe
npx skillsic add owner/repo/skill-name
```

If the skill is blocked (WARNING or DANGER), suggest alternatives:
```bash
npx skillsic search "similar functionality"
```

### Finding Skills for a Task

When a user needs a skill for something:
```bash
# Search returns only analyzed/safe skills by default
npx skillsic search "typescript linting"

# Show detailed info on promising results
npx skillsic info owner/repo/skill-name

# Install the chosen skill
npx skillsic add owner/repo/skill-name
```

### Recommending Skills

When recommending skills, always verify they're analyzed:
```bash
npx skillsic check recommended-skill-id
```

Only recommend skills with SAFE or CAUTION ratings.

## What Gets Checked

The safety analysis evaluates:

1. **Malicious Patterns** - Code that could exfiltrate data, inject backdoors, or cause harm
2. **Security** - Proper handling of secrets, permissions, and sensitive operations
3. **Quality** - Code quality, documentation, maintainability
4. **Privacy** - Data handling and privacy considerations
5. **Trustworthiness** - Source reputation, maintenance status

## Examples

### Example 1: User Asks to Install a Skill

User: "Install the react-best-practices skill"

```bash
# Use skillsic add - it checks safety AND installs
npx skillsic add vercel-labs/agent-skills/vercel-react-best-practices
```

This single command checks safety and installs if safe.

### Example 2: User Wants a Skill for Something

User: "I need a skill for writing better TypeScript"

```bash
# Search for relevant safe skills
npx skillsic search "typescript"

# Install the best match
npx skillsic add owner/repo/chosen-skill
```

### Example 3: User Asks About Skill Quality

User: "Is the remotion skill any good?"

```bash
# Get detailed info (check without install)
npx skillsic info remotion-dev/skills/remotion-best-practices
```

Share the analysis summary, strengths, and weaknesses.

### Example 4: User Wants to Install an Unknown Skill

User: "Install some-random/skill"

```bash
npx skillsic add some-random/skill
```

If it's not analyzed, the output will show [? UNKNOWN] and warn the user, but still allow installation.
