It reports I900 warnings when you use a package that isn't listed in your requirements, helping catch missing dependency declarations before deployment.\n\nThe plugin reads dependencies from setup.py (via eval), setup.cfg, pyproject.toml (PEP 621 or Poetry format), or requirements.txt. It includes a known mapping of package names to module names for common third-party packages, and allows custom mappings via flake8 configuration for private or renamed packages. A critical caveat: because it evaluates setup.py code to extract dependencies, you should only run it on projects you trust.","worth_installing":"Yes, if you want automated validation that your code's imports match your declared dependencies. The low install friction and permissive license make it a straightforward addition to flake8 workflows. However, the aging maintenance status (last release 356 days ago) and the security caveat around eval() of setup.py mean you should only use it on trusted codebases and monitor the project for updates."},"id":"flake8-requirements","links":{"html":"https://skillfed.io/packages/flake8-requirements","md":"https://skillfed.io/packages/flake8-requirements.md","pypi":"https://pypi.org/project/flake8-requirements/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-08-23","license_spdx":null,"license_treatment":"permissive","name":"flake8-requirements","python_support":"supports_current","summary":"Package requirements checker, plugin for flake8"},"popularity":{"monthly_downloads":196184,"position":9793,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.3.0"}
