The Agent Skills Directory

[SAFE]: The skill serves as a comprehensive educational resource for Python developers. It does not contain any executable scripts that run automatically, nor does it include malicious code patterns.
[EXTERNAL_DOWNLOADS]: Documentation references standard, well-known Python packages (such as pytest-cov and freezegun) which are typically installed via public registries during normal development workflows.
[COMMAND_EXECUTION]: Provides standard command-line examples for running pytest and managing test coverage, which are expected in a development-focused documentation skill.
[CREDENTIALS_SAFE]: Code snippets for mocking and environment configuration use clearly identified placeholders (e.g., "test-key", "sqlite:///:memory:") and follow best practices for separating configuration from code.
