Tool Librarian

A Claude skill that keeps a curated library of the tools you have actually vetted, and answers "what should I use for X" out of that library before it reaches for anything else.

You find a good tool, you bookmark it, you forget it, and six months later you google the same question and land on a worse answer. This is the fix for the forgetting half.

Install

Either route installs the skill. Pick whichever fits where you use Claude.

In Claude Code, as a plugin:

/plugin marketplace add jainulabudeenm/tool-librarian
/plugin install tool-librarian

From npm, which also covers Claude.ai and anywhere outside Claude Code:

npx tool-librarian

Add --project to install into the current repo instead of your home directory, so you can commit it and share it with a team.

Use

> add this to my toolbox: https://raycast.com

It drafts the entry, picks a cluster, and asks you to confirm before writing anything.

Then ask for it back.

> what is the best tool for cleaning up a screen recording?

It answers from your library first, names the tool and why it fits this job, and only reaches outside when there is a genuine gap. Anything from outside is labelled as a suggestion, so a vetted pick and a guess never look the same.

Clusters are by vibe, not by function

This is the only opinionated part, and it is what keeps the library usable past fifty entries.

A functional taxonomy sorts by what a tool technically is. Editors here, APIs there, design tools in the third box. It reads tidy and it fails in practice, because it splits up tools you reach for in the same state of mind and shelves together tools you would never consider in the same breath.

Clustering by vibe sorts by the mode you are in when you go looking. You are not thinking "I need a design tool", you are thinking "the visual decision is the hard part today". The library should be organised the way the question arrives.

You get a starter set on first run. Rename it, gut it, grow it. When something genuinely does not fit, the skill proposes a new cluster rather than stretching an old one, because a cluster that means everything means nothing.

The library

~/.claude/tool-librarian/library.md, in your home directory rather than a project folder, so it follows you rather than the repo. Plain markdown, yours to edit by hand whenever you like.

There is no setup step. First run creates the file and gets on with your request. See library.example.md for the shape and the level of detail that makes recall useful.

Not for

Notes, meeting records, or saved conversations. This is one file about one subject. It stays good by staying narrow.
