Agency's Standard Library

Agency has a growing standard library. You can check out all the different functions in the library in the sidebar. To import from the library, use the std:: prefix:

import { search } from "std::wikipedia"

All the functions inside std::index (link) are always pre-imported for you in every file.

There are also some other functions that are built into the language itself:

• interrupt: Use this function to throw an interrupt.
• approve, reject, propagate: Use these functions to respond to an interrupt inside of a handler function.
• schema: Get the Zod Schema for a type.
• llm: Send a message to an LLM system. Set the system prompt.
• checkpoint: Take a snapshot of the current execution state. Returns a checkpoint ID.
• getCheckpoint: Takes a checkpoint ID and returns the checkpoint object.
• restore: Restore a checkpoint. Note that this will completely replace the current execution state with what was saved in the checkpoint. It takes either a checkpoint or a checkpoint ID, along with additional options like overwrites. See here for more details.
• debugger: No op while running the agent, but when running through a debugger, the debugger statement will pause execution.
• isSuccess, isFailure: To be used with a Result type to check whether it is a failure or success.
