Tools

8 tools listed at last check
  • query Search for verified method contracts for any library. Pass any text -- library name, method, what you're building, or an error you hit.
  • list_services List all libraries and services that have verified method contracts. Use this first to discover what's available, then query for specific methods.
  • list_methods List all methods for a given library or service. Use after list_services to drill into a specific one.
  • policy Generate a least-privilege IAM policy for an AWS workflow. Pass a named workflow, explicit IAM actions, or a description. Returns the exact policy with confidence tier and any unresolved operations.
  • list_workflows List the curated named workflows that can generate least-privilege IAM policies.
  • verify Feed a generated policy back to AWS's own policy evaluation engine (SimulateCustomPolicy) and confirm it grants exactly the intended operations and nothing extra. Returns verified (True|False|unknown), grants_all, grants_extra. Requires AWS credentials; without them verified=unknown with the reason.
  • authorize Pre-flight authorization check for an AWS operation. Resolves the IAM actions the operation requires, then asks AWS's own policy simulator (SimulatePrincipalPolicy) whether the current role (or a given principal) allows them. Returns resolution (exact|partial|unresolved) and evaluation (allowed|deni
  • register Register a fix. Three actions: confirm (it worked), append_thread (variant worked), new_receipt (nothing matched, I fixed it).
