AI summary
Auto-generated overview of what this skill does and when to reach for it.
Semia statically analyzes AI agent skills (markdown files with shell/network commands) to produce an evidence-backed security report of every capability they may exercise without ever running them.
Use this when
- you downloaded a skill from a marketplace and want to vet it before use
- you’re reviewing a PR that adds a new skill to your repo
- you’re building a skill and want to catch accidental credential leaks
- you need a SARIF report for GitHub Code Scanning
- you want to auto-patch a skill that fails the audit
Don't use when
- you need to test actual runtime behavior (use sandboxing instead)
- you only care about syntax errors (use a linter)
- you can’t provide an LLM for the synthesize step
Capabilities
- reads skill markdown without executing it
- extracts shell commands, network calls, and tool invocations
- generates a ranked report tied to specific source lines
- exports SARIF 2.1.0 for GitHub Code Scanning
- auto-generates SKILL.md patches to fix violations
- supports OpenAI, Anthropic, Codex, and Claude Code as LLM providers
