Methodology

Scores are computed by deterministic static rules (reproducible). LLMs only explain results in plain language. We show evidence (path / line / snippet) and call out false-positive / false-negative risk.

Dimensions & Weights

overallScore = round( Σ(score_i * weight_i) / 100 )
Dimension Weight Intent
Code Toxicity 30% Dangerous APIs / destructive behavior / dynamic execution
Privacy Risk 25% Sensitive data handling and outbound network risk
Permission Scope 20% Breadth of capabilities (filesystem / network / process / env)
Author Reputation 15% Best-effort trust signals about author and repo
Code Quality 10% Tests / docs / dependency hygiene / CI signals

Risk Level Thresholds

Low >= 80
Medium 60-79
High < 60

Kill Switch

If we detect clearly destructive filesystem operations (e.g. recursive deletion), we immediately classify as High and show the matching evidence on the detail page.

Supply Chain Threat Signals

We add targeted checks for malicious skill distribution and hidden instruction attacks.

  • Blocklist matching on known risky authors, domains, and indicators.
  • Prompt injection checks in SKILL.md (hidden comments and invisible Unicode).
  • Detection of high-risk exfiltration / obfuscation patterns in source files.
  • Toxic flags are shown in cards and detail pages for transparent triage.

Uncertainty & Limitations

Static analysis can produce false positives/negatives. LLMs may hallucinate; they do not affect scoring. Disagreement is surfaced as an explicit signal.

Disclaimer

Reports are best-effort analysis and do not guarantee safety. Always review code and run in isolated environments for sensitive use.
