The description, rendered

This renders the markdown inside the description, so it isn’t quite the description itself.

The raw view and the plain text are the bytes as they were sent.

Fetches full schema definitions for deferred tools so they can be called.

Deferred tools appear by name in <system-reminder> messages. Until fetched, only the name is known — there is no parameter schema, so the tool cannot be invoked. This tool takes a query, matches it against the deferred tool list, and returns the matched tools' complete JSONSchema definitions inside a <functions> block. Once a tool's schema appears in that result, it is callable exactly like any tool defined at the top of the prompt.

Result format: each matched tool appears as one <function>{"description": "...", "name": "...", "parameters": {...}}</function> line inside the <functions> block — the same encoding as the tool list at the top of this prompt.

Query forms:

  • "select:Read,Edit,Grep" — fetch these exact tools by name
  • "notebook jupyter" — keyword search, up to max_results best matches
  • "+slack send" — require "slack" in the name, rank by remaining terms
