It catches two common problems: undeclared dependencies (you import something but forgot to add it to requirements.txt or pyproject.toml, risking runtime errors) and unused dependencies (you listed something but never use it, wasting installation space and increasing breakage risk). The tool scans Python source code in your project directory, parses your dependency declarations, and reports the gaps.\n\nIt depends on standard Python packaging libraries\u2014importlib_metadata, isort, packaging, pydantic, PyYAML, tomli, and pip-requirements-parser\u2014to handle the parsing and comparison. You run it as a command-line tool from your project root, and it outputs a report of what's missing or superfluous. The project is in beta status and supports Python 3.9 through 3.13.","worth_installing":"Yes, if you want automated dependency auditing. The tool is straightforward to install and run, has no known vulnerabilities, and uses permissive MIT licensing. The aging maintenance status (435 days since last release) is a minor concern for a stable linter, but the repository is not archived and remains active. Worth adding to development dependencies to catch dependency mismatches early."},"id":"fawltydeps","links":{"html":"https://skillfed.io/packages/fawltydeps","md":"https://skillfed.io/packages/fawltydeps.md","pypi":"https://pypi.org/project/fawltydeps/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-06-05","license_spdx":null,"license_treatment":"permissive","name":"fawltydeps","python_support":"supports_current","summary":"Find undeclared and unused 3rd-party dependencies in your Python project."},"popularity":{"monthly_downloads":182668,"position":10090,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.20.0"}
