Python docstring generator CLI — Automate your docs

Python teams waste hours manually writing and updating docstrings. Legacy Doc-AI CLI automates this process, scanning your codebase for missing and stale documentation while generating accurate READMEs from actual code.

How it works

Run the CLI on any Python directory to get a full docstring health report:

legacy-doc-ai check ./src/

The tool uses AST parsing to detect:

• Functions without any docstrings
• Stale docstrings that don't match current signatures
• Parameters with missing type hints

Auto-generate with review

Generate docstrings for undocumented functions with a single command:

legacy-doc-ai docstrings ./src/ --dry-run

Review unified diffs before applying changes—just like code reviews. When satisfied, run without --dry-run to write the updates.

Generate README from code

Legacy Doc-AI can also generate a complete README file that reflects your actual API structure, complete with function tables and coverage stats.
