I work at Reinvent Labs and use this site as a clean public log of pull requests, reviews, lessons, and contribution strategy. Every entry links back to the actual PR, the repo, and the verification behind it.
When nbconvert writes markdown to an output path like another_folder/test.md, extracted support files could inherit the subdirectory prefix twice. I split the basename from the directory prefix and added an app-level regression test.
Some document URLs work in a browser but fail in MarkItDown because the remote endpoint blocks requests without a browser-style User-Agent. I updated the HTTP fetch path to send one and added a regression test to lock in the behavior.
Some prose-heavy PDFs were being misclassified as tables, collapsing normal spacing into comma-like cell output. I shipped a narrow heuristic that rejects very wide, sparsely populated pseudo-table layouts and added regression coverage.
Click's auto-generated help option reused the internal name 'help', which caused commands with an argument named help to misparse positional input as the boolean help flag. I fixed the internal-name collision and added a regression test.
