Phase 1: Read Standards

Read the art bible or asset standards from the relevant design docs and the CLAUDE.md naming conventions.

Phase 2: Scan Asset Directories

Scan the target asset directory using Glob:

• assets/art/**/* for art assets
• assets/audio/**/* for audio assets
• assets/vfx/**/* for VFX assets
• assets/shaders/**/* for shaders
• assets/data/**/* for data files

Phase 3: Run Compliance Checks

Naming conventions:

• Art: [category]_[name]_[variant]_[size].[ext]
• Audio: [category]_[context]_[name]_[variant].[ext]
• All files must be lowercase with underscores

File standards:

• Textures: Power-of-two dimensions, correct format (PNG for UI, compressed for 3D), within size budget
• Audio: Correct sample rate, format (OGG for SFX, OGG/MP3 for music), within duration limits
• Data: Valid JSON/YAML, schema-compliant

Orphaned assets: Search code for references to each asset file. Flag any with no references.

Missing assets: Search code for asset references and verify the files exist.

Phase 4: Output Audit Report

# Asset Audit Report -- [Category] -- [Date]

## Summary
- **Total assets scanned**: [N]
- **Naming violations**: [N]
- **Size violations**: [N]
- **Format violations**: [N]
- **Orphaned assets**: [N]
- **Missing assets**: [N]
- **Overall health**: [CLEAN / MINOR ISSUES / NEEDS ATTENTION]

## Naming Violations
| File | Expected Pattern | Issue |
|------|-----------------|-------|

## Size Violations
| File | Budget | Actual | Overage |
|------|--------|--------|---------|

## Format Violations
| File | Expected Format | Actual Format |
|------|----------------|---------------|

## Orphaned Assets (no code references found)
| File | Last Modified | Size | Recommendation |
|------|-------------|------|---------------|

## Missing Assets (referenced but not found)
| Reference Location | Expected Path |
|-------------------|---------------|

## Verdict: [COMPLIANT / WARNINGS / NON-COMPLIANT]

This skill is read-only — it produces a report but does not write files.

Phase 5: Next Steps

• Fix naming violations using the patterns defined in CLAUDE.md.
• Delete confirmed orphaned assets after manual review.
• Run /content-audit to cross-check asset counts against GDD-specified requirements.
