# Grok (xAI) Agent Image
# =============================================================================
# Runs grok-build-0.1 through the opencode CLI (OpenAI protocol) instead of
# Claude Code, while reusing the base image's roboco venv + uv + the RoboCo MCP
# gateway servers. The entrypoint renders opencode.json from the spawn env +
# mounted mcp-config.json (see roboco.llm.providers.opencode_config) and runs
# opencode. One runtime image serves every role — role behaviour comes from the
# mounted system prompt / manifest / mcp-config, exactly as on the Claude path.

# registration route. Each plugin uses a NAMED export (opencode's convention).

#   budget-feed  — POSTs budget/loop/terminal counters to the in-container SDK
#                  server (tool.execute.{before,after}); the entrypoint starts
#                  that server (roboco.agent_sdk.server) for Claude-parity.

# opencode persists data under ~/.local/share and state under ~/.local/state, and
# reads config + plugins from ~/.config/opencode. When the orchestrator
# bind-mounts the opencode store at ~/.local/share/opencode, docker creates the
# intermediate ~/.local AS ROOT, so the non-root agent can no longer create its
# siblings and opencode EACCESes at boot. Pre-create the trees agent-owned so the
# mount leaves the parents writable (complements the orchestrator's 0777
# host-source pre-create), and so the baked plugin dir is agent-owned.
