skill-builder

Reads your shell history, git commits, browser history, and Claude Code conversation logs. Finds patterns you repeat. Generates working skills (slash commands) you can install in Claude Code, Codex, Cursor, or any agent that reads markdown.

Has 15 built-in skills. If you add an API key, it uses an LLM to generate skills for any pattern it finds — not just the built-in ones.

Built this in a day for our own use. If you find it useful, make it better.

git clone https://github.com/Scottpedia0/skill-builder.git

# Preview a skill before installing
node bin/cli.mjs implement pr-dashboard --dry-run

# Install it

If you don't have shell history or want to test with sample data:

node scripts/generate-demo-db.mjs
node bin/cli.mjs suggest --days 7

Reads data from your machine → finds things you do repeatedly → suggests skills to automate them.
