A GROK agent runs opencode, not Claude Code: it has no SDK /usage/status
server and writes no Claude transcript, so _resolve_final_token_usage found
nothing and every Grok agent finalized at 0 tokens / $0 — the opencode_usage
reader existed but had no caller.
- Mount a per-agent opencode data dir ($DATA/opencode/<agent_id> →
/home/agent/.local/share/opencode) so opencode.db is captured, and mount the
same host dir into the orchestrator (/data/opencode) in all three compose
files so the finalizer can read it back — the opencode analogue of the
mounted Claude transcript.
- _resolve_final_token_usage branches on provider_type: GROK reads opencode.db
via opencode_usage (reasoning folded into output, billed at the output rate)
and skips the SDK/transcript path. A 0-token read logs a WARNING so a silent
mount failure isn't mistaken for a real zero-cost run.
- ROBOCO_OPENCODE_DATA_DIR overrides the in-orchestrator path for local runs.
The Grok pr_reviewer wedged in_progress forever: opencode's default agent ran
with the subagent `task` tool enabled, spawned an Explore subagent on
grok-build-0.1 whose model call opened an SSE stream that went idle, and the
run hung with no timeout.
- Hard-disable opencode's subagent `task` tool in the generated opencode.json.
No RoboCo role uses opencode-internal subagents — work flows through the
gateway verbs — so removing the tool kills the hang trigger outright.
- Set provider.xai.options.timeout + chunkTimeout (operator-tunable via
ROBOCO_GROK_REQUEST_TIMEOUT_MS / ROBOCO_GROK_CHUNK_TIMEOUT_MS) as the
defence-in-depth backstop; chunkTimeout aborts an idle stream.
- Bundle the permission + timeout + subagent knobs into an OpencodeGuards
dataclass (keeps the builder under the arg-count gate).
- Drop the dead ROBOCO_AGENT_TOOLS spawn env (it had no consumer); opencode
tool restriction lives in the rendered config now.
grok-build-0.1 reasons heavily by default and reasoning bills at the output
rate (a live "say ok" call emitted ~300 reasoning tokens, ~85% of its cost).
Confirmed live that opencode's `--variant minimal` cuts reasoning ~54%
(298 -> 136 tokens, same prompt).
GrokProvider now picks reasoning effort by role: code-quality roles (developer,
qa, pr_reviewer) keep full reasoning; coordination / docs / board roles
(cell_pm, main_pm, documenter, product_owner, head_marketing, auditor, prompter,
secretary) run "minimal". It's passed to opencode via the entrypoint's
`--variant`. Operators can force one effort for ALL grok agents with the
ROBOCO_GROK_REASONING_EFFORT env (minimal | high | max, or default/full).
Tests cover the role map, the env override, and the spawn env wiring.
Add a roboco/llm/providers/ seam — an AgentProvider lifecycle ABC and a
ProviderRegistry keyed by ModelProvider — so the orchestrator can drive
agent backends other than Claude Code.
The first non-Claude backend is GrokProvider for xAI's grok-build-0.1.
xAI is OpenAI-compatible only (no Anthropic-Messages endpoint), so a Grok
agent runs an OpenAI-protocol runtime pointed at https://api.x.ai/v1
rather than the ANTHROPIC_BASE_URL injection the other providers use. It
reuses the orchestrator's existing mount/auth assembly, so it inherits the
same MCP gateway + tool-manifest wiring as every other agent by
construction, and passes its prompt via env (never an argv positional).
The change is purely additive: only GROK routes through the registry;
Anthropic / Ollama Cloud / self-hosted spawns run the existing
_spawn_container path unchanged.
Includes:
- ModelProvider.GROK (migration 038) + a seeded Grok provider row
(migration 039) + a grok-build-0.1 catalog entry
- GET/PUT /api/providers/grok-key to store the xAI key (Fernet-encrypted,
reusing the existing provider-key machinery)
- ClaudeCodeProvider reference adapter over the current spawn
- unit tests for the registry, GrokProvider (gateway wiring, no
ANTHROPIC_* leak, prompt-injection safety, failure paths) and routing
The dedicated roboco-agent-grok image and the exact OpenAI-protocol CLI
invocation are the remaining piece to finalise with xAI.
