# Runs an agent on xAI's official `grok` CLI (Grok Build), authenticated by the
# SuperGrok subscription via a mounted ~/.grok/auth.json — the parity analogue of
# the Claude Code path's mounted ~/.claude. The gateway, identity, and workspace
# are mounted by the orchestrator's shared container assembly (the same that
# wires Claude); this entrypoint renders the grok runtime config from that mount
# and runs the CLI headless.

# agents run at their workspace-clone cwd, whose own roboco/ dir would shadow it
# on the sys.path front (the ModuleNotFound lesson). The render reads
# ROBOCO_MCP_CONFIG + ROBOCO_AGENT_ID and writes the config + an args file.
