asset-audit

asset-audit is a skill for Claude Code, OpenCode from TraftG/opencode-game-studio. It costs 38 tokens per session (584 once invoked), scanned A, original, MIT.

An audit agent for checking game assets against project rules. It reviews names, file formats, file sizes, references, and required pipeline standards.

In plain words
What is it for?
Auditing art, audio, visual effects, shaders, and data assets; finding orphaned or missing files; and reporting naming, format, size, and schema violations.
Why use it?
It helps find assets that break naming or format rules, are too large, are unused, or are referenced but missing before they cause pipeline or build problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

asset-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

When this skill is invoked:

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

  2. 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
  3. Check naming conventions:

    • Art: [category]_[name]_[variant]_[size].[ext]
    • Audio: [category]_[context]_[name]_[variant].[ext]
    • All files must be lowercase with underscores
  4. Check 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
  5. Check for orphaned assets by searching code for references to each asset file.

  6. Check for missing assets by searching code for asset references and verifying the files exist.

  7. Output the audit:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
