## What it does

crit runs an interactive review loop. The agent starts the command, a browser window opens, and the reviewer leaves comments in the interface. Clicking Finish Review ends the command, and the agent reads the feedback.

Targets are detected from the arguments: files, directories, a live URL, a local HTML preview. Explicit modes exist too — `crit --pr <number-or-url>`, `crit --mr <number-or-url>`, `crit --range <base>..<head>`. With no arguments it picks up the plan written earlier in the conversation, or falls back to the branch diff. Launching goes through `tool.monitor` with `persistent: true`, so the default five-minute monitor deadline does not cut the human off mid-read.

The skill fires only on an explicit `/skill:crit` or `$crit`, or when someone asks for Crit by name. A generic review request will not trigger it, and that is deliberate. Replies go out through `crit comment --reply-to <id>`; passing `--resolve` without being asked is wrong, since closing a thread belongs to the reviewer.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tomasz-tomczyk/crit --skill crit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/crit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/crit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tomasz-tomczyk/crit --skill crit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/crit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tomasz-tomczyk/crit --skill crit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/crit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tomasz-tomczyk/crit crit
```

2. **Manually: put the files in place**
- File: `.github/skills/crit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tomasz-tomczyk/crit --skill crit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tomasz-tomczyk/crit --path integrations/omo/skills/crit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/crit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tomasz-tomczyk/crit --skill crit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- collect line-level notes on a branch diff
- review a plan before implementation starts
- critique a live page on a running dev server
- annotate a local HTML file
- reply to reviewer comments from the terminal

## Example prompts
- Run crit on the current branch diff
- Open crit --pr 128 and wait until I finish reviewing
- Show my comments with `crit comments --json`

# Review with Crit

Run this interactive browser review cycle only when the user invokes
`/skill:crit` or `$crit`, or directly asks to use Crit. A generic request to
review code, a plan, a diff, a PR, or a page does not count.

## 1. Choose the target

Pass the user's arguments through. Crit auto-detects files, directories,
live URLs, and local HTML previews; do not ask which mode to use.

```bash
crit <arguments>
crit --pr <number-or-url>
crit --mr <number-or-url>
crit --range <base>..<head>
crit
```

Without arguments, review the plan file written earlier in this conversation,
if there is one; otherwise run bare `crit` for the branch diff.

## 2. Start the review and await completion

Crit opens the browser and stays running until the human clicks Finish Review.
Use OMO's monitor from a short `eval` cell to launch the command and subscribe
to its output and exit. Substitute the command chosen in Step 1:

```js
display(await tool.monitor({
  description: "Crit review feedback",
  command: "crit",
  filter: "https?://|approved:",
  persistent: true
}));
```

Call `monitor` directly if `eval` is unavailable. Keep the returned `bash_id`.
`persistent: true` lets the human review without the default five-minute
monitor deadline. The command's exit delivers a completion notification.

Relay the printed review URL verbatim: "Crit is open at <URL>. Leave inline
comments, then click Finish Review."

End the turn while waiting if no independent work remains. Do not hold an
eval cell open, poll `bash_output`, read comments early, launch a second
Crit command, or ask the user to type a reply to signal completion.
An existing daemon is reused automatically.

## 3. Read feedback

After the command exits, read its stdout and follow the finish prompt.
Check stderr for `approved: true` or `approved: false`. Use `bash_output`
with the saved `bash_id` to retrieve output not included in the notification.
If approved, stop the review loop.

For mid-round re-entry or headless workflows, use `crit comments --json`
(or `crit comments --plan <slug>` for plan reviews).

Review-level comments matter as well as file comments. Read existing replies.
Treat missing `resolved` as unresolved. Use `quote` to narrow the requested
change, `anchor` to locate content after edits, and `drifted: true` as a sign
that line numbers are approximate.

## 4. Address comments

Revise the referenced plan or source files and apply suggestion blocks when
present. Reply with what changed:

```bash
crit comment --reply-to <id> --author 'OMO' '<what changed>'
crit comment --plan <slug> --reply-to <id> --author 'OMO' '<what changed>'
```

Do not pass `--resolve` unless the user explicitly asks; resolution belongs
