// opencode plugin — the Secretary's CEO-authority tools, on Grok.
//
// Parity with the Claude Secretary's SDK tools (roboco.agent_sdk.secretary_driver
// .build_secretary_options): read_company_state / read_task / submit_directive,
// each calling the backend /api/secretary/* routes with the container's HMAC
// agent token. Without these the Grok Secretary can chat but cannot read company
// state or act on a CEO directive — the integration blocker.
//
// Loaded ONLY into the roboco-agent-grok-secretary image via
// ROBOCO_OPENCODE_EXTRA_PLUGINS (so no other role gets CEO authority). The
// container already carries ROBOCO_AGENT_TOKEN / ROBOCO_API_URL / ROBOCO_AGENT_ID
// / ROBOCO_AGENT_ROLE (set by the orchestrator's _build_secretary_run_cmd), so
// the auth substrate matches the one-shot Grok path exactly.
//
// The backend gate-list queues high-impact directive kinds (charter,
// control_task, approve_pitch, announce) for the CEO's explicit confirmation and
// runs relay_message directly — that policy lives server-side; this plugin only
// forwards the call. Each tool returns the backend JSON as a string the model
// reads back (mirrors secretary_driver._text_result).
//
// Verified live on the NAS: the @opencode-ai/plugin tool-registration path
// round-trips against a live opencode serve + grok-build-0.1 — a directive
// reaches the backend with the HMAC token and the JSON result returns to the model.
