What
In Auto permission mode, launching a subagent whose entire prompt is just one or more URLs no longer raises the usual "Agent tool requires permission to spawn subagents" ask, provided every URL would already be allowed for WebFetch. Anything else about the prompt, and the normal prompt returns.
Details
- Applies only when the session permission mode is auto ("dontAsk"); other modes are unaffected.
- The prompt must be a string containing only URLs, up to a fixed count cap, and each URL is run through the WebFetch tool's own permission check.
- It bails out if the agent type is not offered, or if the session already carries a permission denial record for it.
- The call is tagged as pre-approved for the tool use so a later stage recognises it was cleared here.
- One further disqualifying check exists but is hardcoded to return false, so it can never block this path in this build.
