• HighAS-003

  🔀Scope Mismatch

  get_user_identity_by_subscription:tool name "get_user_identity_by_subscription" implies read-only operation but declares exec permission

  Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

• LowAS-011

  ℹ️Missing Rate-Limit / Timeout ×13

  tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

  Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  🔑Insecure Secret Handling ×2

  input parameter "token" accepts a credential (informational; not evidence of insecure handling)

  unsubscribe_emailupdate_subscription_by_token

  Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.
