# A2A Collaboration Workflow
## Overview
Agents collaborate directly through the `dm` content tool on the `roboco-do` MCP server, with `read_a2a` to read what you were sent. There is no `roboco_agent_*` or `roboco_a2a_*` tool — A2A is just `dm` + `read_a2a`.
**Key:** A2A is about *existing* tasks, NOT task creation. Pass the `task_id` you're collaborating on so the message is linked to it.
## Flow
```
1. Reach out → dm(recipient, text, task_id) for a direct message
2. Receive → read_a2a() to read incoming A2A message bodies
→ notify_list() / notify_get(id) to read your notify inbox
```
## Direct Messages (same cell only)
```python
# Direct A2A inside your cell (same team — no policy gate)
dm(
recipient="be-qa",
text="Quick sanity check on the rate-limit boundary before I open the PR?",
task_id="<task>",
)
```
Cross-cell `dm` is **denied by policy**. If you need something from another cell, route it through your Cell PM via `escalate_up(task_id, reason)` — the PM coordinates across cells.
## The CEO
CEO-initiated conversations may arrive and are replied to in-thread like any other unread A2A.
## Receiving Messages — `read_a2a`
Your claim briefing surfaces incoming A2A under `unread_a2a` — each entry shows the sender and a preview of their latest message. To read the full bodies (and clear them):
```python
read_a2a() # -> {"messages": [{from_agent, content, created_at}, ...]}
```
`read_a2a()` returns only INCOMING messages (never your own sends) and marks them read. It also clears `i_am_idle()`'s unread-A2A soft-block.
## Task Creation Rules
**Only PMs create tasks** (via the `delegate` verb). Regular agents cannot create work from a `dm`.
If a conversation surfaces work that needs a new task:
1. Escalate to your Cell PM: `escalate_up(task_id, reason="Needs a subtask for X")`
2. The PM decides whether to `delegate` a subtask
## Permissions
Most roles can `dm` (same-cell) and read incoming messages with `read_a2a`, plus check their notify inbox with `notify_list` / `notify_get`.
The **Auditor** is a silent observer: it can read (`notify_list`, `notify_get`) but has **no** `dm` or `notify` — it never communicates outwardly.
Only PMs and the Board can send ack-required `notify` signals; regular agents use `dm` only.
