Original Summary

Hi HN, this is a first for me. I use agents for multiple things, from daily life, fitness, video editing, to (performance) engineering. For some of those I have skills globally installed, because I may need them across different projects. But this means in any unrelated task, all skill names + descriptions will still make it into the agent context [1]. This is not the end of the world, but also not great as it could lead to your agent no longer invoking skills reliably (see Addy Osmani&#x27;s <a href="https:&#x2F;&#x2F;addyo.substack.com&#x2F;p&#x2F;audit-your-agent-files" rel="nofollow">https:&#x2F;&#x2F;addyo.substack.com&#x2F;p&#x2F;audit-your-agent-files</a>).<p>With skillzero, you can manage the skills via CLI. It splits them in 3 categories: - hidden skills (entirely removed from context) → they now behave like &#x2F;-commands - collection skills (bundled into <i>one</i> skill, so the agent sees only one name + description) → agent can still invoke these when it thinks it should use them - regular skills (untouched by skillzero)<p>You can install it via npx skillzero (or pnpx or whatever you prefer).<p>[1]: Actually Claude Code &amp; Codex have an optimization, if the name+desc&#x27;s exceed 1%&#x2F;2% of the context window, both will omit some skills entirely.<p>Happy to hear any feedback!

中文标题： Show HN：Skillzero——通过从智能体上下文中省略技能来节省 token

Skillzero 是一个 CLI 工具，把智能体技能分为三类：隐藏技能（从上下文完全移除，行为类似斜杠命令）、集合技能（合并为一个技能，智能体只看到一个名称与描述）和普通技能（不受影响），以减少上下文中的 token 消耗。
