## AI interpretation — verify before relying

Pylint is a static code analyzer for Python that checks for errors, enforces coding standards, detects code smells, and suggests refactoring opportunities without executing the code.

Verdict: Pylint is a mature, actively maintained static analyzer with no known vulnerabilities and broad Python 3.10+ support. Its copyleft GPL-2.0-or-later license is a hard constraint for proprietary codebases. The 9 runtime dependencies are stable and well-established, making installation straightforward. Suitable for projects that can accept GPL licensing and value thorough, inference-based code analysis.
