System reminder: toolsearch deferred

v2.1.284 system reminder: toolsearch deferred

SDK-CLI The prompt of v2.1.284, as Agent SDK, print mode sent it to the model, read out of the request it put on the wire. The text comes first; what changed since the previous capture is further down, kept apart from it.

This is the system reminder: toolsearch deferred request, captured on its own. Its system array, its tools and every count below are this request's, not the ordinary one's. The injected-prompt ledger lists every surface the rig reaches.
