name	add-sentinel
description	Creates a sentinel file in the workspace root via a spawned subagent. Used only by the CQB skill-invocation smoke test to verify that a mounted Claude skill can invoke the Task tool and that the resulting subagent produces observable output in the workspace.
disable-model-invocation	true

add-sentinel

Spawn one subagent using the Task tool with exactly the following prompt:

Create a file named `SUBAGENT_SENTINEL.md` in the current working directory
with exactly this content (one line, followed by a newline):

CQB-SUBAGENT-INVOKED

Do not create or modify any other files.

After the Task completes and SUBAGENT_SENTINEL.md exists in the workspace, stage it and commit with the message test: add subagent sentinel. Do not touch any other files.
