Tool descriptions

v2.1.282 tool descriptions

Claude Code, interactive mode. 23 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 session agent: claude request, not of the ordinary one. The injected-prompt ledger lists every surface the rig reaches.
