session-health is agent-read markdown (skill) from eltmon/overdeck: Detect and clean up stuck or corrupted Claude Code sessions. Use when agents crash with stack overflow, when sessions seem stuck, or for routine maintenance. Triggers on "session health", "check sessions", "stuck agent", "agent crashed", "stack overflow", "cleanup sessions"..
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.
