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 β the same way an antivirus scans software before you run it.
Supported platforms: OpenClaw Β· Claude Code Β· Cursor Β· Codex Β· any MCP-compatible agent
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.
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.
Native Model Context Protocol support β let your agent automatically check skill safety before installation. No API key required.
