 ## Safety Rules
 
-- No agent runs unless a comment or review contains `@codex`, `@claude`, or `@huma`.
+- No agent runs unless a comment or review contains `@SummonAgent` plus `codex`, `claude`, or `huma`.
+- Raw `@codex`, `@claude`, and `@huma` mentions are ignored.
 - Bot users are ignored.
 - Senders must have `write`, `maintain`, or `admin` repository permission.
 - Repositories can be allowlisted in `agent-router.config.json`.
 - The runner claims jobs over an authenticated local API.
 - PR fix jobs only run on fixed lane branches:
-  - `@codex` -> `codex/workspace`
-  - `@claude` -> `claude/workspace`
-  - `@huma` -> `huma/workspace`
+  - `@SummonAgent codex` -> `codex/workspace`
+  - `@SummonAgent claude` -> `claude/workspace`
+  - `@SummonAgent huma` -> `huma/workspace`
 - AgentRouter blocks fork PRs and unexpected PR branches instead of creating new branches.
