A dispatched subagent runs as a nested query that bypasses wizardCanUseTool (the Bash allowlist and .env block) and the read/sandbox limits, so a single spawn escapes every restriction — it can run arbitrary shell and read outside the project (~/.claude, other repos, transcripts). Task agents do not need subagents for the integration flow. Remove the general-purpose subagent definition so there is nothing to dispatch, and hard-deny the Agent/Task tool in wizardCanUseTool as defense in depth.
