Stop writing Claude Code skills by hand. This tool writes them from your sessions.

It’s called autoharness, a self-learning skill layer for Claude Code.

It watches the work you already do and turns it into skills. No separate data collection, no replay loop. It runs on its own once a session has done enough work, or you type /learn to save a lesson right away.

And it keeps the skill folder clean:

→ Merges skills that cover the same scenario instead of adding another near-copy → Updates skills while they’re being used → Archives the ones that stop getting used → Only touches the skills it wrote. Yours are never modified

Why this matters: with the same model, a better harness took CORE-Bench from 42% to 78%. The harness does much of the work, but people still rebuild it by hand for every new model. autoharness bets the skill part can maintain itself.

Two commands to install inside Claude Code. Pure Python, no dependencies.
