Security Findings (5)

• HighExcessive Permission Surface ×2

  • take_screenshot:tool declares network permission
  • check_screenshot_cache: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.
• LowExcessive Permission Surface

  take_screenshot:input schema exposes 13 properties (threshold: 10)

  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 ×2

  • take_screenshot:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • check_screenshot_cache: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.
