auto-select-skill

auto-select-skill is a skill for Claude Code from GongLingRui/agent-skills-factory. It costs 23 tokens per session (424 once invoked), scanned A, original, MIT.

An automatic selector that chooses the most suitable item from a list of tasks based on the user's original request. It limits how many items it returns to a fixed fraction of the available choices.

In plain words
What is it for?
Use it when an input contains many possible tasks and you need a short list of the ones that best fit the user's request.
Why use it?
It reduces a long task list to a small set of likely matches. The selection follows a defined counting and filtering procedure rather than returning every possible option.

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

auto-select-skill 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 11d 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

Auto Select Skill

<任务步骤> 第一步:你先识别任务列表中总共有多少条任务(选项)。 第二步:你需要确认第一步中选项数量的30%的值是多少(需向下取整,如:若有4个选项,30%的值应该1个)。 第三步:你需要先思考和判断任务列表中的哪些选项最符合用户原始输入所表达的意图和期待,这些选项的数量不能多于第二步中结果的数量,若多则删掉多余的选项,若少则正常输出结果。 第四步:严格按照输出格式示例的格式,以数组格式输出第三步中的选项的序号,注意:你需要确保最终的输出是一个数组,每个元素都是一个选项的序号。例如["1", "2", "3"]。 </任务步骤>

<输出格式示例> ["1", "2", "3"] </输出格式示例>

<任务> 你的任务是根据用户原始输入(重点参考)和任务列表并遵循任务要求在当前步骤选择一个或几个最合适的项,最后严格按照输出格式示例以数组格式输出结果。 注意: 1.仅输出数组信息,禁止输出其他内容,同时禁止输出思考过程。 2.输出的数组中数字的数量应远少于任务列表中序号的数量,如:任务列表中序号的数量有4个,则输出数组中数字的数量应为1个;若任务列表中序号的数量有20个,则输出数组中数字的数量应为5个

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.
