Parse the agent DSL from the request payload

Oct 13, 2025 by wbrum.org 39 views

Introduction

In the realm of system management, flexibility and scalability are crucial for efficient operation. One key aspect of this is the ability to add agents to a system at any point in time, not just during initialization. To achieve this, we propose the implementation of a new HTTP endpoint for systems/{id}/agents/. This endpoint will enable the creation and addition of agents to an already initialized system, using a payload DSL (Domain Specific Language). In this article, we will delve into the requirements, implementation details, and benefits of this new endpoint.

Description

The proposed HTTP endpoint, systems/{id}/agents/, will allow users to create and add agents to an existing system. This is a significant enhancement to the current system management capabilities, providing more flexibility in managing agent lifecycles. The endpoint will accept a payload DSL, which will be parsed and used to register the agent AST (Abstract Syntax Tree) and the agent itself with the system.

Requirements

To implement this endpoint, we need to meet the following requirements:

1. Create a POST endpoint at `systems/{id}/agents/`

We will create a new POST endpoint at the specified URL, which will accept a payload DSL and create a new agent.

2. Implement handler to:

Parse the agent DSL from the request payload: The handler will parse the payload DSL and extract the necessary information to create the agent.
Register the agent AST: The handler will register the agent AST with the system, which will be used to configure the agent.
Register the agent with the system: The handler will register the agent with the system, making it available for use.
Optionally start the agent based on request parameters: The handler will start the agent based on the request parameters, if specified.

Implementation Details

To implement this endpoint, we will leverage the existing AgentCreationRequest and AgentCreationResponse models. We will also use the System's register_agent_ast and register_agent methods to register the agent AST and the agent itself with the system.

Existing Models

We will use the existing AgentCreationRequest and AgentCreationResponse models to handle the request and response payloads.

System Methods

We will leverage the System's register_agent_ast and register_agent methods to register the agent AST and the agent itself with the system.

Error Handling and Validation

We will add appropriate error handling and validation to ensure that the request is valid and the agent is created successfully.

API Documentation

We will update the API documentation to reflect the new endpoint and its usage.

Benefits

The implementation of this endpoint will provide several benefits, including:

On-time agent addition: The endpoint will enable the creation and addition of agents to an already initialized system, providing more flexibility in managing agent lifecycles.
Improved system management: The endpoint will enhance system management capabilities, making it easier to manage agents and their lifecycles.
