pyagentspec 26.1.0

Package defining the PyAgentSpec library for Agents and LLM fixed-flows abstractions.

🔗 Open Agent Specification (PyAgentSpec)

Agent Spec is a portable, platform-agnostic configuration language that allows Agents and Agentic Systems to be described with sufficient fidelity. It defines the conceptual objects and called components that compose Agents in typical Agent systems, including the properties that determine the components' configuration, and their respective semantics. Agent Spec is based on two main runnable standalone components:

• Agents (e.g., ReAct), that are conversational agents or agent components;
• Flows (e.g., business process) that are structured, workflow-based processes.

Runtimes implement the Agent Spec components for execution with Agentic frameworks or libraries. Agent Spec would be supported by SDKs in various languages (e.g. Python) to be able to serialize/deserialize Agents to JSON/YAML, or create them from object representations with the assurance of conformance to the specification.

For more information, including the motivation and specification, see the dedicated section in the Agent Spec documentation.

🧠 Quick Start

1) Configure an LLM

Initialize a Large Language Model (LLM) of your choice using PyAgentSpec configs:

OCI Gen AI	Open AI	Ollama
from pyagentspec.llms import OciGenAiConfig from pyagentspec.llms.ociclientconfig import OciClientConfigWithApiKey OCIGENAI_ENDPOINT = "https://inference.generativeai..oci.oraclecloud.com" COMPARTMENT_ID = "ocid1.compartment.oc1..<compartment_id>" llm = OciGenAiConfig( name="OCI model", model_id="model_id", compartment_id=COMPARTMENT_ID, client_config=OciClientConfigWithApiKey( name="client_config", service_endpoint=OCIGENAI_ENDPOINT, auth_file_location="~/.oci/config", auth_profile="DEFAULT", ), )	from pyagentspec.llms import OpenAiConfig llm = OpenAiConfig( name="OpenAI model", model_id="model_id", )	from pyagentspec.llms import OllamaConfig llm = OllamaConfig( name="Ollama model", url="ollama_url", model_id="model_id", )

See the list of supported LLMs in the PyAgentSpec documentation: https://oracle.github.io/agent-spec/development/howtoguides/howto_llm_from_different_providers.html

2) Create an Agent

from pyagentspec.agent import Agent
from pyagentspec.property import Property

expertise_property = Property(json_schema={"title": "domain_of_expertise", "type": "string"})
system_prompt = """
You are an expert in {{domain_of_expertise}}.
Please help the users with their requests.
"""

agent = Agent(
    name="Adaptive expert agent",
    system_prompt=system_prompt,
    llm_config=llm_config,  # from step 1
    inputs=[expertise_property],
)

🚀 Execute Agent Spec configurations

Agent Spec configurations can be executed using Agent Spec–compatible runtimes or adapters that translate the spec into the target framework representation.

• WayFlow is an Agent Spec reference runtime developed by Oracle: https://github.com/oracle/wayflow/
• PyAgentSpec includes adapters for common frameworks (install extras as needed). Examples are available in the adapters_examples folder:
  • LangGraph: https://github.com/oracle/agent-spec/tree/main/adapters_examples/langgraph
  • AutoGen: https://github.com/oracle/agent-spec/tree/main/adapters_examples/autogen

Refer to the installation guide for adapter-specific extras: https://oracle.github.io/agent-spec/development/installation.html
