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's https://addyo.substack.com/p/audit-your-agent-files).

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 /-commands - collection skills (bundled into one 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)

You can install it via `npx skillzero` (or `pnpx` or whatever you prefer).

[1]: Actually Claude Code & Codex have an optimization, if the name+desc's exceed 1%/2% of the context window, both will omit some skills entirely.

Happy to hear any feedback!
