Skill File Analysis

Every public scanner assumes the threat lives in server dependencies. The threat lives in SKILL.md.

Use Case
AutoGPT's skill files were reading .env on every agent load.

CHK-115 found credential access patterns in 3 SKILL.md files in Significant-Gravitas/AutoGPT (184k stars). The files instructed the agent to read .env and pass API keys to subsequent tool calls. AI-confirmed CRITICAL.

CHK-115: credential access in skill content
CHK-112: base64 obfuscation detection
CHK-113: brand impersonation and typosquatting
CHK-114: ASCII smuggling and hidden unicode

How it works
01
Connect your GitHub org
OAuth in 30 seconds. AISS discovers every MCP server, skill file, hook, and agent config across all repos.
02
22 modules scan in parallel
CVE lookup, secret scanning, auth checking, tool description analysis, skill file parsing — all concurrent, all hand-written.
03
LLM verifies high-severity
Critical and high findings go to an LLM verifier before reporting. No false positives reach your CISO.
04
Gate, alert, or export
Block in CI via SARIF. Send to SIEM via NDJSON. Export CycloneDX SBOM. Enforce allowlist/blocklist policy.
