matcher 对 agent_type。continue:false 拦不住启动。内部 Review/Compact 不跑这个事件。

```
[[hooks.SubagentStart]]
matcher = "reviewer"

[[hooks.SubagentStart.hooks]]
type = "command"
command = '/usr/bin/python3 "$(git rev-parse --show-toplevel)/.codex/hooks/subagent_start.py"'
timeout = 10
statusMessage = "Loading reviewer context"

```
