## What it does

The skill gives Cursor Composer the diff between a base ref and `HEAD`, its change statistics, and the requested scope. Composer runs read-only and looks for bugs, regressions, missing tests, and unsafe assumptions. Each finding should include its location, trigger, impact, and evidence that can be checked.

The flow uses `cursor-companion.sh`, `resolve-impl-backend.sh`, and `model-routing.sh`. It resolves the Harness root through `HARNESS_PLUGIN_ROOT`, `CLAUDE_PLUGIN_ROOT`, or `CLAUDE_SKILL_DIR`. The base ref comes from `TASK_BASE_REF` or falls back to `origin/main`; pass `--base <ref>` to select another one. Cursor reports findings, but it cannot issue `APPROVE` or `REQUEST_CHANGES`.

The skill must not pass `--write` to `cursor-companion.sh`, so the review does not modify files. If the Harness root cannot be resolved, the run exits with an error.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Chachamaru127/claude-code-harness --skill cursor-review -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Chachamaru127/claude-code-harness --skill cursor-review -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Chachamaru127/claude-code-harness --skill cursor-review -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Chachamaru127/claude-code-harness cursor-review
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Chachamaru127/claude-code-harness --skill cursor-review -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Chachamaru127/claude-code-harness --path skills/cursor-review
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Chachamaru127/claude-code-harness --skill cursor-review -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Chachamaru127/claude-code-harness/tree/HEAD/skills/cursor-review/SKILL.md

## When to use it
- review a diff against `origin/main`
- ask Cursor for an independent code review
- spot regressions and missing tests
- separate observed defects from hypotheses
- keep the final verdict with the host reviewer

## Example prompts
- Run `cursor:review --base origin/main` and inspect the full diff.
- Use `cursor:review` to review a command namespace change.
- Ask Cursor to sanity-check the current diff in read-only mode with `cursor:review`.

# cursor:review - Advisory Cursor Review

Cursor Composer (`composer-2.5-fast`) を read-only second opinion として使う review skill。primary verdict は host brain (Opus / Claude role) が出す。

## Quick Reference

```bash
cursor:review --base origin/main
cursor:review "Phase 88.5 command namespace diff"
```

## Rules

- Cursor review is advisory. The final verdict must come from the host reviewer.
- Do not pass `--write` to `cursor-companion.sh`.
- Use resolver/model routing, not direct env checks:

  ```bash
  bash scripts/resolve-impl-backend.sh --backend cursor --role reviewer
  bash scripts/model-routing.sh --host cursor --role worker --field model
  ```

- Prefer the existing `harness-review` contract when a full review is requested. This command exists for users who explicitly ask for the Cursor lane.

## Flow

1. Resolve the Harness helper root:

   ```bash
   HARNESS_PLUGIN_ROOT="${HARNESS_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-}}"
   if [ -z "$HARNESS_PLUGIN_ROOT" ] && [ -n "${CLAUDE_SKILL_DIR:-}" ]; then
     probe="$(cd "${CLAUDE_SKILL_DIR}" && pwd)"
     while [ "$probe" != "/" ] && [ ! -d "$probe/scripts" ]; do
       probe="$(cd "$probe/.." && pwd)"
     done
     [ -d "$probe/scripts" ] && HARNESS_PLUGIN_ROOT="$probe"
   fi
   if [ -z "$HARNESS_PLUGIN_ROOT" ]; then
     echo "ERROR: HARNESS_PLUGIN_ROOT is not set and could not be derived from CLAUDE_PLUGIN_ROOT or CLAUDE_SKILL_DIR" >&2
     exit 2
   fi
   ```

2. Determine review scope:

   ```bash
   BASE_REF="${TASK_BASE_REF:-origin/main}"
   REVIEW_SCOPE="${ARGUMENTS:-}"
   if [ -n "${REVIEW_SCOPE}" ]; then
     set -- ${REVIEW_SCOPE}
     while [ "$#" -gt 0 ]; do
       case "$1" in
         --base)
           BASE_REF="${2:?--base requires a ref}"
           shift 2
           ;;
         --base=*)
           BASE_REF="${1#--base=}"
````
