feat(claude-code): add crit-tui, an early review pane mod for Claude Code

[tomasz-tomczyk]

What

A second plugin in the crit marketplace: crit-tui, a mod that brings the crit review loop into Claude Code (Claude Code 2.1.287+). It's opt-in and versioned on its own (0.1.0), so the main crit plugin doesn't change.

/plugin marketplace add tomasz-tomczyk/crit
/plugin install crit-tui@crit

How it works

• /crit-tui opens a pane next to the transcript: the conversation, the git diff, or a file (/crit-tui chat|diff|file <path>).
• Click a line to move the cursor; drag to select exact text, across lines too. Keys: c comment, r reply, x resolve, s send, ? for the rest.
• Threads show inline under their lines, with drafts and new replies marked.
• s sends new comments and replies to Claude as one prompt. Claude answers each item in its thread with the mcp__crit-tui__reply tool. You resolve.
• A band above the prompt and the status line show what's waiting to be sent and what's new from Claude.

Where comments live

Everything goes through the crit CLI, so crit comments and the browser UI see the same review:

• Diff and file comments: the repo's review file, via crit comment --json, with quote / quote_offset for partial selections (feat(cli): accept quote and quote_offset in crit comment --json #1013).
• Chat comments: a crit plan per session (claude-chat-<session id>), saved with crit plan --no-wait (feat(plan): add --no-wait to save a plan version without a review #1014) and commented with crit comment --plan. With an older crit, chat comments stay in the session.

Files

• integrations/claude-code-tui/: the plugin (hooks module, the pane's Client module, model, state types, tests, README)
• .claude-plugin/marketplace.json: the new plugin entry
• cmd/crit/integration_hashes_gen.go: regenerated

Testing

• claude plugin validate integrations/claude-code-tui and claude plugin validate .: pass
• claude plugin test integrations/claude-code-tui: 24 tests (documents, review prompt, the pane driven by keys and mouse, crit CLI calls for code and chat comments)
• Used in live Claude Code sessions while building it
• go test ./cmd/crit/: pass
