Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Grok Harness (ACOS + Grok Build) Grok Build (xAI Grok CLI/TUI) is a first-class harness in the 5-fleet (Claude canonical, Grok, Antigravity/AGY, Gemini, Codex). ACOS provides deep integration via `grok-harness-adapter` (adapters/grok/index.ts + install.sh --platform=grok). ## Quick Start in Grok ```bash # From any project ./install.sh --platform=grok # or in ACOS source itself # Then: grok /hooks-trust /skills harness-integration # or just describe: "use repo-mastery on this ACOS change + gstack qa if UI" ``` Grok loads (priority): - Project: GROK.md + .grok/skills/ (highest) + .grok/hooks/ + .grok/agents/ - Global: ~/.grok/skills/ + ~/.grok/hooks/ - Compat: ~/.claude/skills/ + ~/.claude/ (full ACOS catalog via junctions) ## The 4 grok-personal .grok-Only Excellence Seeds (SIP §5 encoded-self; .grok ONLY) Per SHARING.md + SIP, these stay ONLY in project .grok/skills/ (never in ACOS core .claude or shared flat catalog): 1. **harness-integration** — SessionStart excellence + PreToolUse gates + auto repo-mastery + multi-delegate + claude compat. …

How to install
mdr add frankxai/agentic-creator-os/grok-harness@sha256:367bee215458c6a4The line at the top of this page pins the label git:20260611.d712d7e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
