Tools

• authorize ~256 tokens
  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
• list_methods ~91 tokens
  List all methods for a given library or service. Use after list_services to drill into a specific one.
• list_services ~68 tokens
  List all libraries and services that have verified method contracts. Use this first to discover what's available, then query for specific methods.
• list_workflows ~49 tokens
  List the curated named workflows that can generate least-privilege IAM policies.
• policy ~184 tokens
  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.
• query ~185 tokens
  Search for verified method contracts for any library. Pass any text -- library name, method, what you're building, or an error you hit.
• register ~157 tokens
  Register a fix. Three actions: confirm (it worked), append_thread (variant worked), new_receipt (nothing matched, I fixed it).
• verify ~221 tokens
  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.
