claude-harness-canary is agent-read markdown (skill) from gtapps/claude-code-hermit: Run the minimum current-Claude compatibility canary for claude-code-hermit by driving real interactive Claude Code instances in tmux with --plugin-dir. Use before a core release or after a Claude Code upgrade to verify cached model switching, unattended prompt safety, and native Monitor/Cron routine lifecycle. Core only; not application testing or CI..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
