Best for
- Claude Code users who want skills learned from their own work without writing them by hand
- Keeping a self-maintaining skill library that consolidates near-duplicates
- Project-level or global skill layers with tunable lifecycle limits
- Logging skill create/update decisions for later evaluation
Install
/plugin marketplace add tigerless-labs/autoharness
/plugin install autoharness@autoharnessOur take
Requires Python 3.11+ as the python3 on PATH; an older interpreter first on PATH (such as macOS Xcode's 3.9.6) silently disables the hooks for the session. It only modifies skills it authored itself, and those skills plus its state directory remain on disk after uninstall. Reflection runs in background child sessions every 50 tool calls by default, so lowering the cadence increases spawned sessions, and supported platforms are Linux and macOS.
