10 free skills, ready to install

No waitlist, no card. Install them into Claude Code or upload them to claude.ai, and each one reads your brain.md to do the work in your voice.

These 10 are the finished part of a 137-job map. The other 127 jobs are specified and not yet built — you can read the map, but there is nothing to install for those.

Installing

Claude Code

Two commands inside Claude Code. All 10 arrive together.

/plugin marketplace add bobbyxx7/skilltree-skills
/plugin install skilltree@skilltree-skills

Prefer plain files in ~/.claude/skills/? The README has the per-skill link-them-yourself version.

claude.ai

Download a skill folder from the repo, zip it with the folder at the root of the archive, then upload the zip under Settings → Customize → Skills.

cd skills && zip -r ../sop-writer.zip sop-writer

In your browser

Nothing to install. Join the waitlist and https://app.skilltree.pro runs three of these — the interview, the cold email writer and the invoice chaser — with your own Anthropic API key. The key stays in your browser and we never see it: the only things that page ever sends to our server are the access check that gets you in — which carries no key and no prompt — and, if you ask it to re-send your link, the address to send it to. The files above need no account at all.

You need a key from console.anthropic.com, and runs are billed to you. The two paths above cost nothing beyond your existing Claude plan.
