1,184+ malicious skills were confirmed in the ClawHavoc campaign.
In early 2026, security researchers confirmed 1,184+ malicious AI skills across 12 compromised publisher accounts, distributing Atomic Stealer malware, stealing credentials, and exfiltrating data via ClickFix social engineering. SkillSafe was built so this cannot happen here — every skill is scanned before sharing and independently re-verified on install, with cryptographic tamper detection between publish and download.
Labeling vs. Gating.
Scanning a skill at install time tells you it was clean when you downloaded it. It doesn't tell you it's the same file the publisher uploaded — or that critical findings will actually stop the install.
No scanning
- Anyone publishes without security review
- No verification at any point
- Community flags damage after it happens
- No integrity check on downloaded archives
Scan-and-label
e.g. skills.sh (Snyk + Socket + Gen)
- Scanned at install — not before publishing
- Critical findings shown as warnings, install still proceeds
- No publisher-side scan before the skill is shared
- No tamper detection between publish and download
SkillSafe: scan-and-gate
- Publisher scans before sharing — not after
- Consumer independently re-scans on install
- Critical verdicts block the install automatically
- Cryptographic tree hash detects any tampering in transit
Key Features
Dual-Side Verification
Sharers scan before sharing. Consumers re-scan after download. The server compares both reports — tampered skills are flagged immediately.
Cryptographic Tree Hashes
Every archive is SHA-256 hashed into an immutable tree hash. If a single byte changes, verification fails with a critical verdict.
Semantic Versioning
Strict semver enforcement and version yanking. Install exactly the version you need, every time.
Share Links
Share skills via revocable links with expiration controls. Private by default — share when you're ready, revoke anytime.
Built for AI Tools
Works with Claude Code, Cursor, Windsurf, Codex, Gemini, OpenCode, OpenClaw, Cline, Roo, Goose, GitHub Copilot, Kiro, Trae, AMP, Aider, VS Code, Antigravity, Droid, and Kilo Code. One registry across all your AI agents — no vendor lock-in, no separate extensions needed.
Free to Use
Save up to 50 private skills per day for free. Share with cryptographic verification at no cost. Upgrade only when you need more storage or team features.
How It Works
1
Publisher Scans
The publisher runs a full security scan before sharing. Every file is analyzed for malicious patterns and vulnerabilities, producing a detailed report and cryptographic tree hash.
2
Registry Stores
The scan report is stored alongside an immutable SHA-256 tree hash. Any byte change between save and install breaks the hash — tamper-proof by design.
3
Consumer Verifies
On download, the consumer independently re-scans and the server compares both reports. Only matching scans receive a verified verdict.
Quick Start
1
Install
Send this to your AI agent:
Create skillsafe skill from
https://skillsafe.ai/skill.mdYour AI tool reads the skill definition, downloads the client, and sets up SkillSafe automatically.
2
Sign In & Save
skillsafe auth
skillsafe save ./my-skill --version 1.0.0Opens your browser to sign in. Your skill is saved privately — no scan or email verification required.
Optional — requires email verification + scan
skillsafe share @myname/my-skill --version 1.0.0Sharing creates a cryptographically verified link others can install. Shared skills are scanned before sharing and re-verified on install.
3
Install & Verify
skillsafe install @skillsafe/code-reviewDownloads, independently re-scans, and verifies the report against the publisher's. Blocks installation on critical verdicts and warns on divergent results.
