What

The safety check that reviews a subagent's work when it returns control to the main agent gained a second, trimmed prompt variant alongside the existing one, which asks the reviewer to flag dangerous files and give the main agent a reason.

Details
  • Both sit next to the existing two-stage grading prompts.
  • Which variant is used is decided at the call site, and the code does not make the condition explicit.
Evidence

Subagent has finished and is handing back control to the main agent. Review the subagent's work for anything dangerous under the block rules.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
