feral-core skillA

feral-core is agent-read markdown (skill) from stijnman/grok-custom-skills: Unified godlevel feral engine that combines autonomous-skill-forge, beta-unlocker, godlevel-secret-hunter and skill-persistence-guard into one high-autonomy entry point. Use when the user wants maximum power, go feral, unlock, secret skills, growth rounds, instant implementation, all-out mode, or when any of the four core skills would normally be called. Detects gaps, hunts secrets, unlocks soft locks, restores missing skills, self-levels, and persists. One skill to rule the feral stack..

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.
