Security Findings (4)

• HighExcessive Permission Surface ×2

  • linkup-search:tool declares network permission
  • linkup-fetch: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 ×2

  • linkup-search:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • linkup-fetch: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.
