# ADR 6: @all-bots via Dedicated Zulip Bot User

**Date**: 2026-04-28

### Decision
@all-bots is implemented as a dedicated Zulip bot user with display name `All Bots` and email `all-bots@chat.sysloggh.net`. All 6 per-agent bots subscribe to the same event narrow and detect when `All Bots` is in `mentioned_users`.

### Context
@all-bots needs to trigger all agents regardless of platform. A dedicated bot user is explicit and intentional — it prevents @everyone or stream-wide pings from accidentally triggering all agents. Each bot independently detects the @mention and forwards to its agent.

### Consequences
- Must create a 7th Zulip bot user for `All Bots`
- Each agent bot's config must include `All Bots` user ID for detection
- @all-bots is opt-in: only topics that explicitly @all-bots trigger broadcast
- Cross-platform broadcast works without a central dispatcher
