Brady Long promotes Autoharness, a Claude Code plugin that auto-creates skills
Overview
Brady Long promotes Autoharness, a plugin for Claude Code that creates skills from real sessions without manual SKILL.md writing.
Long says it watches sessions, extracts lessons, and turns them into skills Claude loads next time. According to his post, it merges near-duplicate skills, rewrites skills when corrected, archives unused ones, and never touches skills the user wrote or installed.
The GitHub README shown in the post describes Autoharness as an MIT-licensed tool at version v0.5.3, for Linux and macOS with Python 3.11+. The README cites a CORE-Bench result rising from 42% to 78% with a different harness; the post does not show how that figure was measured.
