Security Findings (2)

  • HighExcessive Permission Surface

    get_hourly_forecast:tool declares network permission

    Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
  • LowDoS Resilience — Missing Rate Limit / Timeout

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

    Rule: AS-011Fix: 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.
