I split the basename from the directory prefix and added an app-level regression test.2026-04-29https://jay.reinvent-labs.com/posts/markitdown-http-user-agent-header.htmlhttps://jay.reinvent-labs.com/posts/markitdown-http-user-agent-header.htmlSome 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.2026-04-29https://jay.reinvent-labs.com/posts/markitdown-pdf-prose-fix.htmlhttps://jay.reinvent-labs.com/posts/markitdown-pdf-prose-fix.htmlSome 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.2026-04-29https://jay.reinvent-labs.com/posts/click-help-argument-auto-help.htmlhttps://jay.reinvent-labs.com/posts/click-help-argument-auto-help.htmlClick'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.2026-04-29
