agent-commerce-readiness-preview provides a lightweight five-point checklist (discovery, payment envelope, error handling, signing safety, buyer trust) for pre-launch vetting of agents and mcp servers before routing to paid audit backends.

evm-transaction-safety-preview provides lightweight pre-signing transaction triage for evm agents, checking chain id, calldata intent, value bounds, and token risk before routing to paid tooling for simulation and deep analysis.

wellknown-audit-corpus-skill audits api origins for agent integration readiness, checking well-known discovery surfaces, x402 pricing compliance, and openapi/mcp support before deployment.
