There is **no**`roboco_task_*` tool surface. Tasks move through the lifecycle via **flow verbs** on the `roboco-flow` MCP server. Each verb is role-scoped — you only see the ones your role is allowed to call (the spawn manifest registers them per role). Every verb returns an **Envelope** whose `next` field tells you what to call next; trust it rather than guessing state.
There is no separate claim / start / pause verb — `i_will_work_on` composes claim + set-plan + start atomically, and `i_am_done` composes verify + submit-qa. Branches are auto-created on `i_will_work_on`; do not checkout by hand.
`notes` (on pass_review) and `issues` (on fail_review) must be substantive — the enforcement layer rejects empty or near-empty content. QA cannot review its own dev work (self-review guard rejects on `claim_review`).
After `i_will_plan` and each `delegate`, the envelope includes a coverage view of the parent — `parent_ac_coverage` (per-criterion `id` / `text` / `claimed` / `verified`) and `unclaimed_parent_acs` (criteria no subtask covers yet). A parent cannot idle with unclaimed criteria, nor `complete` / `submit_up` / `escalate_to_ceo` until every criterion traces to a child that passed QA. These gates stay inert until you start declaring `covers_parent_criteria`. See `docs/rag/workflows/task-planning.md`.
**Delegation rules** (enforced): `main_pm -> cell_pm`; `cell_pm -> its team's devs`. Cell PMs receive planning-typed parent tasks; devs get code/research (UX devs also design). Always create subtasks via `delegate` with `parent_task_id` set — there is no standalone task-create verb for agents.
The Main PM shares most Cell PM verbs (`i_will_plan`, `delegate`, `complete`, `unblock`, `triage`, `escalate_up`), **adds** the two below, and — unlike a Cell PM — has **no**`submit_up` or `reassign` (there is no PM above it to submit to; it completes or escalates the root directly):
Cancelling a task (any non-terminal status -> `cancelled`) is restricted to **PM roles and the CEO**. There is no agent verb to cancel — it is a PM/CEO operation through the lifecycle.
