What is music-catalog?

A lookup tool for a built-in, fixed catalogue of singers and songs. It can answer only from the catalogue included with the skill.

Use it to search the catalogue by singer name. The required script returns the matching information as JSON.

It prevents answers from being made up or drawn from unapproved sources. When a singer or song is missing, the result must say that it was not found.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00016	$0.00140
Opus 5.5	$0.00006	$0.00056
Sonnet 5.5	$0.00003	$0.00028
Haiku 4.5	$0.00002	$0.00014

Security

Grade A, and why

music-catalog 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/find-by-artist.py), 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.

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

音乐目录查询

只可使用本 Skill 包内的静态歌曲目录回答音乐查询，未查询到时必须明确说明。

查询歌手歌曲时：

调用 execute_skill_script。
使用 skillName: "music-catalog"。
使用 scriptPath: "scripts/find-by-artist.py"。
arguments 只传一个歌手名称字符串，例如 ["林俊杰"]。
根据脚本返回的 JSON 回答，不得编造目录中不存在的歌曲。

Files

What ships with it

2 files 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.
