Tool descriptions

v2.1.280, every tool

Agent SDK, print mode. 17 tools, as the client described them to the model in this release. Where a tool has more than one description the difference is usually a single interpolated string.

These are the tools of the system reminder: toolsearch deferred request, not of the ordinary one. The injected-prompt ledger lists every surface the rig reaches.
