The Agent Skills Directory

[SAFE]: The skill provides detailed and secure instructions for configuring Python testing environments using well-known and trusted tools including pytest, Hypothesis, mutmut, tox, and nox.
[SAFE]: The included auditing script, scripts/check_test_config.py, is a read-only utility designed to detect common configuration errors (e.g., shadowed config files). It uses the standard Python tomllib for parsing and does not involve network activity or privileged operations.
[SAFE]: External URLs in the documentation refer exclusively to official project documentation (e.g., pytest.org, coverage.readthedocs.io), academic research platforms (e.g., dl.acm.org, arxiv.org), and established open-source repositories (e.g., github.com/boxed/mutmut).
[SAFE]: The skill instructions avoid dangerous practices such as remote script piping (curl | bash), unnecessary sudo usage, or the handling of sensitive credentials.
[SAFE]: The skill includes defensive guidance against common pitfalls in AI-assisted development, such as ensuring tests are not weakened by agents to achieve a 'green' status.
