# Grok (xAI) Agent Image
# =============================================================================
# Runs Grok Build through xAI's official `grok` CLI, authenticated by the
# SuperGrok subscription via a mounted ~/.grok/auth.json — the parity analogue of
# the Claude Code path's mounted ~/.claude (no metered API key). Reuses the base
# image's roboco venv + uv + the RoboCo MCP gateway servers. The entrypoint
# renders ~/.grok/config.toml (the gateway) + the per-role grok flags from the
# mounted mcp-config.json (see roboco.llm.providers.grok_cli_config) and runs the
# CLI headless. One runtime image serves every role — role behaviour comes from
# the mounted system prompt / manifest / mcp-config, exactly as on the Claude path.

USER root

# Install the official grok CLI (Grok Build) for the agent user. The installer's
# default is $HOME/.grok/bin, so the binary lands at ~/.grok/bin/grok alongside
# its runtime (downloads / bundled / skills) under ~/.grok, all agent-owned.
# NO version pin (2026-07-28 policy: latest-at-build, always adapt — fleet-wide
# across grok/gemini/codex/kimi). Download the installer to a file first (a
# `curl | bash` pipe hides a curl failure as a silent no-op) and verify the
# binary installed AND runs, so a broken install fails the build here, not at
# spawn; the resolved version is stamped to /etc/grok-cli-version (build-log +
# on-disk provenance, not a pin — the next build reinstalls whatever's latest).
