# agent-harness

> One-command installer and curator of vetted AI-coding skills, plugins, rules, and hooks by tech stack — across Claude Code (first-class), Codex, OpenCode, and Antigravity. Project-scoped by default; no global pollution. Install with `npx -y @uzysjung/agent-harness` (interactive wizard) or `npx -y @uzysjung/agent-harness install --track <name> --cli <claude|codex|opencode|antigravity>` (non-interactive; `--track` is required). MIT.

agent-harness curates by tech stack: of the vetted options, you install only what your project actually needs, instead of piling on skills and MCPs that just bloat an agent's context. "Vetted" means every catalog asset is ≥1000 GitHub stars, actively maintained, and verified by a real install in an isolated Docker container (35/52 green today; the rest are repo-bundled templates verified by the CI file-placement matrix), re-checked monthly for star-drift. It is **not** a line-by-line security audit or a prompt-injection scan of asset contents; npm/npx assets are version-pinned, while plugin/skill assets resolve to upstream HEAD. Claude Code is first-class; Codex, OpenCode, and Antigravity receive the skills + rules layer (the compatibility matrix states exactly what reaches each CLI).

- [Usage](https://github.com/uzysjung/uzys-agent-harness/blob/main/docs/USAGE.md): commands, flags, install scopes (project vs global)
- [Workflows & catalog](https://github.com/uzysjung/uzys-agent-harness/blob/main/docs/WORKFLOWS.md): curated workflow assets (OpenSpec and BMAD; Superpowers and ECC were retired in v26.159.0) with measured star counts
