code-review	Performs an architectural and quality code review on a specified file or set of files.

Phase 1: Load Target Files

Read the target file(s) in full. Read CLAUDE.md for project coding standards.

---

Phase 2: Identify Engine Specialists

Read .claude/docs/technical-preferences.md, section ## Engine Specialists. Note:

• The Primary specialist (used for architecture and broad engine concerns)
• The Language/Code Specialist (used when reviewing the project's primary language files)
• The Shader Specialist (used when reviewing shader files)
• The UI Specialist (used when reviewing UI code)

If the section reads [TO BE CONFIGURED], no engine is pinned — skip engine specialist steps.

---

Phase 3: ADR Compliance Check

Search for ADR references in the story file, commit messages, and header comments. Look for patterns like ADR-NNN or docs/architecture/ADR-.

If no ADR references found, note: "No ADR references found — skipping ADR compliance check."

For each referenced ADR: read the file, extract the Decision and Consequences sections, then classify any deviation:

• ARCHITECTURAL VIOLATION (BLOCKING): Uses a pattern explicitly rejected in the ADR
• ADR DRIFT (WARNING): Meaningfully diverges from the chosen approach without using a forbidden pattern
• MINOR DEVIATION (INFO): Small difference from ADR guidance that doesn't affect overall architecture

---

Phase 4: Standards Compliance

Identify the system category (engine, gameplay, AI, networking, UI, tools) and evaluate:

• Public methods and classes have doc comments
• Cyclomatic complexity under 10 per method
• No method exceeds 40 lines (excluding data declarations)
• Dependencies are injected (no static singletons for game state)
• Configuration values loaded from data files
• Systems expose interfaces (not concrete class dependencies)

---

Phase 5: Architecture and SOLID

Architecture:

• Correct dependency direction (engine <- gameplay, not reverse)
• No circular dependencies between modules
• Proper layer separation (UI does not own game state)
• Events/signals used for cross-system communication
• Consistent with established patterns in the codebase

SOLID:

• Single Responsibility: Each class has one reason to change
• Open/Closed: Extendable without modification
• Liskov Substitution: Subtypes substitutable for base types
• Interface Segregation: No fat interfaces
• Dependency Inversion: Depends on abstractions, not concretions

---

Phase 6: Game-Specific Concerns

• Frame-rate independence (delta time usage)
• No allocations in hot paths (update loops)
• Proper null/empty state handling
• Thread safety where required
• Resource cleanup (no leaks)

---

Phase 7: Engine Specialist Review

If an engine is configured, spawn engine specialists via Task in parallel with the review above. Determine which specialist applies to each file:

• Primary language files (.gd, .cs, .cpp) → Language/Code Specialist
• Shader files (.gdshader, .hlsl, shader graph) → Shader Specialist
• UI screen/widget code → UI Specialist
• Cross-cutting or unclear → Primary Specialist

Also spawn the Primary Specialist for any file touching engine architecture (scene structure, node hierarchy, lifecycle hooks).

Collect findings and include them under ### Engine Specialist Findings.

Phase 8: Output Review

## Code Review: [File/System Name]

### Engine Specialist Findings: [N/A — no engine configured / CLEAN / ISSUES FOUND]
[Findings from engine specialist(s), or "No engine configured." if skipped]

### ADR Compliance: [NO ADRS FOUND / COMPLIANT / DRIFT / VIOLATION]
[List each ADR checked, result, and any deviations with severity]

### Standards Compliance: [X/6 passing]
[List failures with line references]

### Architecture: [CLEAN / MINOR ISSUES / VIOLATIONS FOUND]
[List specific architectural concerns]

### SOLID: [COMPLIANT / ISSUES FOUND]
[List specific violations]

### Game-Specific Concerns
[List game development specific issues]

### Positive Observations
[What is done well -- always include this section]

### Required Changes
[Must-fix items before approval — ARCHITECTURAL VIOLATIONs always appear here]

### Suggestions
[Nice-to-have improvements]

### Verdict: [APPROVED / APPROVED WITH SUGGESTIONS / CHANGES REQUIRED]

This skill is read-only — no files are written.

Phase 9: Next Steps

• If verdict is APPROVED: run /story-done [story-path] to close the story.
• If verdict is CHANGES REQUIRED: fix the issues and re-run /code-review.
• If an ARCHITECTURAL VIOLATION is found: run /architecture-decision to record the correct approach.
