Shipped: Harneo, a harness manager for Claude Code

If you use Claude Code across many repos, your harness (skills, commands, subagents, hooks, settings.json, MCP servers, CLAUDE.md) gets copied by hand from project to project. The copies drift, nobody remembers where a skill came from, and risky ones slip in.

Harneo is an open-source desktop app (plus a CLI) that keeps one library of the artifacts you trust, imported from GitHub repos with a trust score and an audit. You build profiles from that library and install one into any project. Every install is previewed, backed up and reversible. It also notices when a project's files drift from the library, and Harnmap shows your setup as a factory map so you can test a new skill against it before you install it.

I run my own setup from it: 80 artifacts from 5 sources in my library. It's on v0.3.1, MIT, with Linux AppImage/.deb packages and source builds for macOS and Windows.
