What is SkillFortify?

The first formal security scanner for AI agent skills, using mathematical proofs (Dolev-Yao model, abstract interpretation) to verify skill safety. Supports 22 agent frameworks.

How does SkillFortify differ from other security scanners?

It provides mathematical guarantees — if no violations are reported, capability bounds are formally assured. Heuristic scanners can miss threats; SkillFortify uses sound static analysis.

Which agent frameworks does SkillFortify support?

22 frameworks including MCP, LangChain, CrewAI, OpenClaw, Claude SKILL.md format, and others. It auto-discovers skill files on your system.

Why was SkillFortify created?

In response to the ClawHavoc campaign (1,200+ malicious skills) and CVE-2026-25253 (RCE in agent skill runtime). Existing scanners couldn't provide formal safety guarantees.

Is SkillFortify open source?

Yes, available at github.com/qualixar/skillfortify. Published research paper on arxiv (2603.00195).

SkillFortify — first formal security scanner for AI agent skills, 22 frameworks supported

qualixar/skillfortify provides mathematically grounded security analysis using Dolev-Yao model, abstract interpretation, capability sandboxing. Supports MCP, LangChain, CrewAI, OpenClaw. arxiv 2603.00195. Two Show HN posts. Response to ClawHavoc campaign (1200 malicious skills).

Product Idea from this Signal

A background service that continuously scans your running OpenClaw instance against the latest CVE database, detects configuration drift from secure baselines, and auto-patches or alerts before exploits land

2.5k ▲

OpenClaw accumulates 2.2 new CVEs per day. 63% of deployed instances are running vulnerable versions. The gap between disclosure and patch application averages days to weeks for self-hosters. Enterprise users running Tank OS or formal scanners like SkillFortify cover the skill layer, but nobody monitors the runtime. This service watches the CVE feed, compares against your installed version and enabled features, and either auto-applies safe patches or fires an alert with exact remediation steps before your instance gets hit.
