Asset Manager

Asset Manager is a skill for Claude Code, Codex from daffy0208/ai-dev-standards. It costs 37 tokens per session (4,311 once invoked), scanned A, original, MIT.

A system for organizing, naming, optimizing, and versioning design files such as images, icons, logos, fonts, and videos. Versioning keeps track of changes so teams can identify and restore earlier asset versions.

In plain words
What is it for?
Use it to structure asset folders, apply naming rules, optimize images and fonts, manage logo variants, and maintain a production-ready brand library.
Why use it?
It reduces time spent searching for files and helps prevent inconsistent names, formats, or outdated assets from reaching production. It also keeps brand materials easier to reuse.

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 Manager scanned grade A with 1 finding 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 9d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

Asset Manager

Keep design assets organized, optimized, and accessible.

Core Principle

Organized assets = faster development.

Assets should be:

  • Easy to find
  • Properly named
  • Optimized for production
  • Version controlled
  • Consistently formatted

Automated Organization Script

const rules: AssetRule[] = [

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
