## What it does

This skill reviews one design document before it reaches programmers. It reads the document in full, checks project context in `CLAUDE.md`, and uses `design/registry/entities.yaml` for cross-document facts when that registry is present.

Before a repeat pass, `design-review` compares the document with prior review receipts through `review-receipts.sh`. An unchanged file can reuse an earlier verdict, while changes in the registry trigger a check of related facts. That matters when a document itself stayed unchanged but its dependencies did not.

Use `--review full|lean|solo` to set review depth. The former `--depth` flag is accepted as an alias, but `--review` takes precedence when both appear. `full` delegates to specialist agents, `lean` stays in one session, and `solo` is intended for calls from another skill.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill design-review -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill design-review -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill design-review -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Donchitos/Claude-Code-Game-Studios design-review
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill design-review -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Donchitos/Claude-Code-Game-Studios --path .claude/skills/design-review
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill design-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/Donchitos/Claude-Code-Game-Studios/tree/HEAD/.claude/skills/design-review/SKILL.md

## When to use it
- review a design document before implementation
- detect conflicts with the entity registry
- check a GDD against `CLAUDE.md`
- reuse a verdict for an unchanged document
- set review depth with `--review`

## Example prompts
- Review `design/gdd/combat.md` with design-review.
- Run design-review on `design/gdd/economy.md` using `--review lean`.
- Check `design/gdd/progression.md` with `--review solo`.

!`bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys review_mode,automation,workflow,system_overrides`

Resolved above — use as-is; `--review` overrides `review_mode`. `--depth` is
the pre-1.1 name for the same flag: treat `--depth <mode>` exactly as
`--review <mode>`, and say once that it was renamed. Given both, `--review`
wins and `--depth` is ignored — say so. No block → defaults in
`.claude/docs/config-resolution.md`.

# Design Review


## Phase 0: Parse Arguments


See `.claude/docs/director-gates.md` for the full check pattern. Individual gate definitions live in `.claude/docs/director-gates/[gate-id].md` — the spawned agent reads its own gate file; do not read it in the parent session.


Every `AskUserQuestion` call follows `.claude/docs/automation-modes.md`
(collaborative asks always · guided major-only · autonomous logs and proceeds;
`automation_always_ask` categories always prompt).

- `full` — all 8 sections validated; any missing section blocks approval.
- `standard` — the 5 required sections (Overview, Detailed Rules, Edge Cases,
  Dependencies, Acceptance Criteria) block if missing; Formulas blocks only when
  the system defines numeric rules (rates, curves, thresholds, costs — the
  category is a hint, not the test); Player Fantasy and
  Tuning Knobs are advisory (warn, never block) unless `workflow_overrides`
  require them.
- `minimal` — no GDD is expected; if one exists, validate the 5 standard
  sections advisorily.

Resolved mode controls how thorough this review is:

- **`full`**: Complete review — all phases + specialist agent delegation (Phase 3b)
- **`lean`**: All phases, no specialist agents — faster, single-session analysis
- **`solo`**: Phases 1-4 only, no delegation, no Phase 5 next-step prompt — use when called from within another skill

## Phase 1: Load Documents

**Freshness check first — a re-review of an unchanged document costs full
price and reproduces the same verdict.** Run:

```
Bash: bash .claude/scripts/review-receipts.sh check "design/gdd/reviews/[doc-name]-review-log.md" "[target-doc-path]" "design/registry/entities.yaml" ".claude/skills/design-review/SKILL.md"
```
