StoryMind: Skill for Claude Code

.agents/skills/media-use/SKILL.md

media-use is a skill for Claude Code, Codex from LinHao-city/StoryMind. It costs 84 tokens per session (1,456 once invoked), scanned C, original, AGPL-3.0.

A media-file resolver that finds background music, sound effects, images, or icons and saves a chosen file locally with a record of where it came from.

In plain words
What is it for?
Use it to find and cache media for a composition, then pass the saved file path to the rest of the work.
Why use it?
It avoids repeating media searches and gives the agent a stable local file instead of search results to sort through.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is LinHao-city/StoryMind's own configuration. It tells Claude Code and Codex how to work on StoryMind itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything StoryMind configures →

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 C, and why

media-use scanned grade C with 2 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 11d ago.

The scan reads SKILL.md. This mod also ships 17 executable files (scripts/eval.mjs, scripts/lib/adopt.mjs, scripts/lib/bgm-provider.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
