## What Is SkillsSafe?

As AI agents become more powerful, malicious skills can steal credentials, exfiltrate data, or hijack your agent's behavior. SkillsSafe scans skill files before you install them — the same way an antivirus scans software before you run it.

**Supported platforms:** OpenClaw · Claude Code · Cursor · Codex · any MCP-compatible agent

---

## Features

### 🔍 Security Scanner
Paste content, enter a URL, or upload a file to scan for:

| Threat | Description |
|---|---|
| **Credential Theft** | Attempts to access API keys, tokens, or passwords |
| **Data Exfiltration** | Skills that send your data to external servers |
| **Prompt Injection** | Hidden instructions that hijack agent behavior |
| **Shell Injection** | Reverse shell or arbitrary command execution |
| **Zero-Width Characters** | Invisible Unicode characters hiding malicious instructions |
| **Scope Creep** | Skills requesting permissions beyond their stated purpose |
| **Memory Poisoning** | Attempts to corrupt agent memory or context |
| **Privacy Risk** | Unnecessary access to personal or sensitive data |

Each scan returns a **risk score**, severity rating (SAFE / CAUTION / DANGER / CRITICAL), and a shareable report link.

### 👁️ Zero-Width Character Detector
Visualize invisible Unicode characters (`U+200B`, `U+200C`, `U+200D`, `U+FEFF`, etc.) hidden inside text. Attackers embed these to create prompts that look safe to humans but carry hidden instructions for AI agents.

### 🔌 MCP Server Integration
Native Model Context Protocol support — let your agent automatically check skill safety before installation. No API key required.

```bash
# OpenClaw (one-line setup)
openclaw mcp add https://skillssafe.com/api/mcp
```

**Available MCP tools:**
- `scan_url` — Scan a skill by URL
- `scan_content` — Scan skill content directly
- `get_report` — Retrieve a full scan report

### 📡 REST API
Works with any agent, script, or CI/CD pipeline.

```bash
# Scan by URL
curl -X POST https://skillssafe.com/api/v1/scan/url \
  -H "Content-Type: application/json" \
  -d '{"url": "https://clawhub.ai/skills/example"}'

# Scan by content
curl -X POST https://skillssafe.com/api/v1/scan/content \
  -H "Content-Type: application/json" \
  -d '{"content": "...skill content..."}'
```
