What

The built-in claude-test plugin's read-only explorer subagent (a helper agent meant only to look around, not make changes) is now also barred from using the claude_test_app_up tool, which launches the app under test. This is in addition to the existing block on claude_test_allow.

Why

This keeps the explorer subagent strictly read-only, preventing it from starting up the application, which is an action beyond simple exploration.
