Prevent the tool from reading environment variables and sending them to external endpoints. If env access is needed, restrict it to specific variable names via an allowlist.

Likely FP if the match is documentation about how to configure environment variables, not code that reads and transmits them.

Restrict network connections to standard ports (80, 443) and explicitly allowlisted service ports. Block connections to unusual ports that could indicate covert channels.

Likely FP if the non-standard port is localhost (127.0.0.1) used for local development servers (e.g., port 3000, 8080, 5432 for a local database).

Validate and sanitize all data received from external APIs before using it in tool operations or agent prompts. Implement schema validation and treat API responses as untrusted input.

Likely FP if the match is a truncated table cell or documentation fragment that mentions API responses in a descriptive context, not actual unvalidated data processing.
