Security Findings (18)

• HighExcessive Permission Surface ×3

  • set_api_key:tool declares network permission
  • check_api_key:tool declares network permission
  • get_image_fills: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.
• HighInsecure Secret Handling

  set_api_key:input parameter "api_key" appears to accept a secret or credential

  Rule: AS-010Fix: 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.
• MediumScope Mismatch

  set_api_key:tool name "set_api_key" implies local write operation but only remote/network-class permissions were detected

  Rule: AS-003Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.
• MediumExcessive Permission Surface ×10

  • get_file:tool declares fs permission
  • get_file_nodes:tool declares fs permission
  • get_image:tool declares fs permission
  • get_image_fills:tool declares fs permission
  • get_comments:tool declares fs permission
  • post_comment:tool declares fs permission
  • delete_comment:tool declares fs permission
  • get_project_files:tool declares fs permission
  • get_file_components:tool declares fs permission
  • get_file_styles:tool declares fs 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 ×3

  • set_api_key:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • check_api_key:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • get_image_fills: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.
