Review and revise code changes, plans, live pages (running dev servers, staging URLs), or local HTML files using crit for inline comment review.
critThe CLI auto-detects the review mode from its arguments. Do not ask the user which mode to use. Pass arguments through:
crit <arguments> # file, dir, URL, .html — CLI auto-detects mode
crit --pr <num|url> # GitHub PR (range mode)
crit --range <base>..<head> # commit range (range mode)
crit # no args → branch diff
If no arguments, check conversation context:
crit <plan-file>crit (branch diff)CRITICAL — you MUST run this step. Do NOT skip it. Do NOT proceed without it.
Run crit in the foreground and block until it exits:
crit <plan-file> # specific file
crit # git mode
If a crit server is already running from earlier in this conversation, crit automatically connects to it. Starting from scratch, it spawns the daemon, opens the browser, and blocks until the user clicks "Finish Review".
crit prints the review URL on startup (e.g. Started crit daemon at http://localhost:<port>). Relay it verbatim:
"Crit is open at http://localhost:. Leave inline comments, then click Finish Review."
Do NOT proceed until crit completes. Do NOT ask the user to type anything. Do NOT read the review file early. Wait for the foreground command to finish — that is how you know the human is done reviewing.
When crit completes, its stdout includes the path to the review file (e.g. "Review comments are in /path/to/review.json"). Read it.
The file contains structured JSON. Three comment types:
review_comments (top-level, r_-prefixed IDs) — general feedbackcomments array, no start_line/end_line) — about the file as a wholecomments array, with start_line/end_line) — about specific linesIdentify all comments where resolved is false or missing. Unresolved comments may have replies — read them before acting.
When a comment has these fields:
quote: the specific text the reviewer selected — focus your changes on the quoted text rather than the entire line rangeanchor: use it to locate the current position of the content; line numbers may be stale after editsdrifted: true: original content was removed or heavily rewritten — line numbers are approximate at bestFor each unresolved comment:
crit comment --reply-to <id> --author 'Cursor' '<what you did>' (reply bodies support markdown)--resolve. Resolving is the reviewer's call. Only add --resolve if the user explicitly asks.Editing the plan file triggers Crit's live reload — the user sees changes in the browser immediately.
Use --json for a single bulk call instead of one invocation per comment:
echo '[
{"reply_to": "c_a1b2c3", "body": "Fixed"},
{"reply_to": "c_d4e5f6", "body": "Refactored as suggested"}
]' | crit comment --json --author 'Cursor'
If there are zero review comments: inform the user no changes were requested and stop.
CRITICAL — you MUST run this step. Do NOT skip it. Do NOT proceed without it.
When Step 2's crit command exits with feedback, it prints Next round: crit <args> to stdout. Run that command verbatim — the daemon is keyed by args, so mismatched args spawn a new daemon instead of reconnecting.
On subsequent calls, crit automatically signals round-complete first, then blocks until the next "Finish Review" click.
Tell the user: "Changes applied. Review the diff in your browser and click Finish Review when ready."
Do NOT proceed until crit completes. When it does, return to Step 3. If the user finishes with zero comments, the review is approved — stop the loop and proceed.
If the user asks for a URL, a shareable link, or to share the review:
crit share <file>
Always relay the full output to the user — copy the URL directly into your response. Don't make them dig through tool output.
To remove a shared review:
crit unpublish [file...]
Only use --qr in real terminal environments with monospace rendering. Skip it in mobile apps or web chat UIs — Unicode block characters won't render.
crit share --qr <file>
Review code changes, a plan, a live page (running dev server), or a local HTML file with crit inline comments. Use when asked to review code, a plan, a diff, a running web app, or when you want structured human feedback on your work.
Use when an agent needs to author or reply to crit inline comments programmatically (including multi-agent workflows commenting on shared code/plans/docs/proposals), publish or unpublish a crit review with crit share, sync a crit review to or from a GitHub PR, or read/interpret a crit review JSON file. Covers crit comment, crit share, crit unpublish, crit pull, crit push, review file format, and resolution workflow. Not for invoking an interactive review loop — that's the `/crit` command.
