Simon Willison introduced a new Python CLI tool called claude-code-transcripts, which converts Claude Code transcripts into detailed HTML pages. This tool enhances the usability of the transcripts, making them more accessible and shareable. Users can run the command `uvx claude-code-transcripts` to begin, or install it via `uv tool install` or `pip`. The output includes an index.html file summarizing the transcript and additional HTML files with full details. For those using the gh CLI tool, there’s an option to automatically share transcripts as GitHub Gists. Willison emphasizes the importance of these transcripts, as they encapsulate crucial context about his coding projects and decisions made during interactions with Claude Code. Previously, he relied on traditional issue tracking for context, but with the shift toward using Claude Code, he found it necessary to extract and document these conversations more effectively. He built this tool after several failed attempts to create shareable formats from Claude Code sessions. The development process was largely facilitated by Claude, with dependencies including Jinja2 for HTML templating and questionary for user interaction. The only part not generated by Claude was reverse-engineering the API for the web version of Claude Code, which he accomplished using OpenAI's Codex.
