Tool descriptions

v2.1.284 tool descriptions

Agent SDK, print mode. 20 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: read dup request, not of the ordinary one. The injected-prompt ledger lists every surface the rig reaches.
