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).

Pin all pip packages to exact versions (e.g., pip install package==1.2.3). Use a requirements.txt or pyproject.toml with pinned versions and hash verification.

Likely FP if the match is in documentation showing how to install the skill's own PyPI package.
