The catalog

71 guardrails, each labelled with what it does.

71 guardrails for AI coding agents. Each one carries a label for what it does: it blocks, asks you, warns, or is advice the agent reads. The catalog has 72 policies. 1 more is deprecated and not shown here: rtk-dangerous-actions-blocker.

Each build counts these from the catalog. Labels and counts are the catalog's grades on Claude Code. Each policy's page lists its grade on every agent.

CI GitHub Actions Security

ci-github-actions-security

Warns v0.0.4

EU AI Act — High-Risk Triage

eu-ai-act-high-risk-triage

Warns when code puts an AI system into an EU AI Act Annex III high-risk domain — biometrics, critical infrastructure, education, employment, essential services and credit, law enforcement, migration, justice and elections — and asks for an owner of the Article 9-15 obligations before the capability ships.

Flag Downloads Run as Code in Files

block-fetch-exec-in-files
