rerun_llm_with_output_format

• rerun_llm_with_output_format<T>(options): Promise<TypeOf<T>>

• Re-run LLM with a different output format using existing conversation history

  This "time travels" by:

  1. Taking the current message history (minus the last cortex message that triggered this call)
  2. Rebuilding the system prompt with section overrides via PromptManager
  3. Running a structured completion with the custom schema

  By default, preserves all original prompt sections. Use sectionOverrides to:

  • Replace section args: { responseGuidance: ['Custom guidance...'] }
  • Exclude a section entirely: { functions: null }

  Useful when a function needs the LLM to extract structured data from the conversation but the main CortexOutput format isn't granular enough.

  Type Parameters

  • T extends ZodType<any, ZodTypeDef, any>

  Parameters

  • options: {
        schema: T;
        schema_name: string;
        sectionOverrides?: node.common.apis.cortex.SectionOverrides;
    }

    • schema: T

    • schema_name: string

    • OptionalsectionOverrides?: node.common.apis.cortex.SectionOverrides

  Returns Promise<TypeOf<T>>

• Parameters

run_code_output

• run_code_output(output): Promise<node.common.apis.cortex.FunctionResult>

• Executes JavaScript code in sandbox instead of running function calls

  Parameters

  • output: node.common.apis.cortex.CodeOutput

  Returns Promise<node.common.apis.cortex.FunctionResult>

run_cortex_output

• run_cortex_output(co): Promise<node.common.apis.cortex.FunctionResult>

run_llm

• run_llm(loop?): Promise<string>

• Run the LLM with the specified system message, message history, and parameters If loop=N, after obtaining a function response another LLM call will be made automatically, until no more functions are called or until N calls have been made
