Show HN: Collaborate on Documents with Claude Code (github.com)

claude-review is a lightweight browser companion for Claude Code that turns the usual copy‑and‑paste review loop into an inline, document‑centric collaboration flow. It renders Markdown files in the browser where you can highlight text, add anchored inline comments and threaded discussions (like Google Docs or Confluence), and then push those comments back into the same Claude Code session that generated the document. Claude Code can fetch threads, ask clarifying questions, make edits, and resolve threads; the browser auto-refreshes on file changes so you see updates immediately. Technically it’s a CLI tool for Linux/macOS that integrates with the Claude Code workflow: install via the provided curl installer which places a binary in ~/.local/bin and registers slash commands (/cr-review and /cr-address) under ~/.claude/commands. Usage: have Claude Code create a Markdown file, run /cr-review to open the review URL, annotate in-browser, then run /cr-address in the Claude session to import threads. The approach preserves agent context, anchors feedback precisely, and shortens human–agent iteration from minutes to seconds—making agent-assisted document authoring, review, and refinement much more efficient and conversational. For architecture and deeper details the repo includes an ARCHITECTURE doc.
