This reduces token usage\n * and helps the main model focus on the right tools.\n *\n * @param options - Configuration options for the middleware\n * @param options.model - The language model to use for tool selection (default: the provided model from the agent options).\n * @param options.systemPrompt - Instructions for the selection model.\n * @param options.maxTools - Maximum number of tools to select. If the model selects more,\n *   only the first maxTools will be used. No limit if not specified.\n * @param options.alwaysInclude - Tool names to always include regardless of selection.\n *   These do not count against the maxTools limit.\n *\n * @example\n * Limit to 3 tools:\n * ```ts\n * import { llmToolSelectorMiddleware } from \"langchain/agents/middleware\";\n *\n * const middleware = llmToolSelectorMiddleware({ maxTools: 3 });\n *\n * const agent = createAgent({\n *   model: \"openai:gpt-4o\",\n *   tools: [tool1, tool2, tool3, tool4, tool5],\n *   middleware: [middleware],\n * });\n * ```\n *\n * @example\n * Use a smaller model for selection:\n * ```ts\n * const middleware = llmToolSelectorMiddleware({\n *   model: \"openai:gpt-4o-mini\",\n *   maxTools: 2\n * });\n * ```\n */\nexport declare function llmToolSelectorMiddleware(options: LLMToolSelectorConfig): ReturnType<typeof createMiddleware>;\n//# sourceMappingURL=llmToolSelector.d.ts.map"],"mappings":";;;;;;;;;;AAOqBI,cAAAA,4BA6BnB,EA7BiDJ,CAAAA,CAAEe,SA6BnD,CAAA;EAzBqCV;;;EAAgIG,KAAAA,EAA5JR,CAAAA,CAAEW,WAA0JH,CAA9IR,CAAAA,CAAEU,QAA4IF,CAAAA,CAAlIR,CAAAA,CAAEK,SAAgIG,EAArHR,CAAAA,CAAES,OAAmHD,CAA3GP,iBAA2GO,CAAAA,OAAAA,EAAvHF,qCAAAA,CAAsFC,4BAAAA,CAAiCC,EAAFR,CAAAA,CAAEQ,UAAAA,EAAYP,iBAAZO,CAAAA,OAAAA,EAAUF,qCAAAA,CAA4EC,4BAAAA,CAAtFC,CAAAA,CAAAA,CAAAA,CAAAA;EAAUF;;;EAAtJI,YAAAA,EAITV,CAAAA,CAAEW,WAJOD,CAIKV,CAAAA,CAAEK,SAJPK,CAAAA;EAAdC;;;;EASGA,QAAAA,EAAFX,CAAAA,CAAEW,WAAAA,CAAYX,CAAAA,CAAEY,SAAdD,CAAAA;EAK8BN;;;;EACtBC,aAAAA,EADLN,CAAAA,CAAEW,WACGL,CADSN,CAAAA,CAAEa,QAE4DN,CAFnDP,CAAAA,CAAEK,SAEiDE,EAAAA,MAAAA,CAAAA,CAAAA;CAA1EN,EAAAA,OAAAA,EADTD,CAAAA,CAAEc,UACOb,EAAAA;EAAiBK,KAAAA,CAAAA,EAAAA,MAAAA,GAAjBL,iBAAiBK,CAKyDC,OAAAA,EANvED,qCAAAA,CACuEC,4BAAAA,CAKAA,GAAAA,SAAAA;EAA1EN,YAAAA,CAAAA,EAAAA,MAAAA,GAAAA,SAAAA;EAzBgCc,QAAAA,CAAAA,EAAAA,MAAAA,GAAAA,SAAAA;EAAS,aAAA,CAAA,EAAA,MAAA,EAAA,GAAA,SAAA;AA8B9D,CAAA,EAAA;EAuCwBE,KAAAA,CAAAA,EAAAA,MAAAA,GA5CHhB,iBA4C4B,CAAA,OAAA,EAjDXK,qCAAAA,CAKyDC,4BAAAA,CA4C9C,GAAA,SAAA;EAAUS,YAAAA,CAAAA,EAAAA,MAAAA,GAAAA,SAAAA;EAA0Cb,QAAAA,CAAAA,EAAAA,MAAAA,GAAAA,SAAAA;EAAlBe,aAAAA,CAAAA,EAAAA,MAAAA,EAAAA,GAAAA,SAAAA;AAAU,CAAA,CAAA;KAvCjFF,qBAAAA,GAAwBd,4BAA4BE;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;iBAuCxCa,yBAAAA,UAAmCD,wBAAwBE,kBAAkBf"}
