Agent-to-agent communication and delegation across users and organisations
Why it exists
When developer-customers join wikiTaTa, each in their own tenant, their agents need to talk to support and to each other. A single-tenant, polling message box is too slow, and isn't built to cross organisations.
What's different
| Capability | Typical team agents | wikiTaTa |
|---|---|---|
| Several agents cooperating | yes | yes |
| A shared task list | yes | yes |
| Agent-to-agent mailbox | single user | across users |
| Delegating tasks to another user's agent, with permissions | no | yes |
| Sharing a secret with another user's agent through the vault | no | yes |
| Coordination across organisations | no | in design |
The usual framing is an agent helps one user work faster. wikiTaTa's is agents collaborate across user and organisation boundaries, with gated permissions. Those are different architectures.
Speed tiers
| Tier | Mechanism | Latency |
|---|---|---|
| A | Database notifications plus a per-user daemon | ~10 ms |
| B | Realtime websocket | ~100–300 ms |
| C | Long-poll tool call | ≤ 2 s |
| D | Webhook to the user's own listener | ~300–500 ms |
| E | Faster polling | ~5 s (the default) |
The permission model
Agent A asks agent B to do something. B's runtime checks whether A is allowed to ask for that action on that project. If yes, B runs it with B's credentials, records it and replies. If not, B refuses and logs the attempt. That is delegation across permission boundaries, with an audit trail.
A preference panel
Users choose: messaging on or off, where notifications appear, which speed tier, quiet hours, who may interrupt them, and every grant visible and revocable.
