dapr-agents-oas-adapter 0.8.0

Adapter library to make Dapr Agents compatible with Open Agent Spec

dapr-agents-oas-adapter

Bidirectional conversion between Open Agent Spec (OAS) and Dapr Agents.

Overview

dapr-agents-oas-adapter enables seamless interoperability between Open Agent Spec (OAS) specifications and Dapr Agents. Import OAS specifications to create executable Dapr Agents and workflows, or export existing Dapr Agents to portable OAS format.

Key Features

• Bidirectional conversion -- Import OAS specs into Dapr Agents and export back to OAS
• Schema validation -- Validate OAS specifications before conversion with detailed error reports
• Caching -- In-memory cache with configurable TTL for repeated operations
• Async support -- Non-blocking loader for high-throughput applications
• Structured logging -- Built-in structlog integration for observability

Installation

pip install dapr-agents-oas-adapter

Or with uv:

uv add dapr-agents-oas-adapter

Quick Start

Load an OAS spec and create a Dapr Agent

from dapr_agents_oas_adapter import DaprAgentSpecLoader

loader = DaprAgentSpecLoader()
config = loader.load_yaml(oas_yaml)
agent = loader.create_agent(config)

Export a Dapr Agent to OAS format

from dapr_agents_oas_adapter import DaprAgentSpecExporter

exporter = DaprAgentSpecExporter()
oas_dict = exporter.to_dict(config)

Validate before conversion

from dapr_agents_oas_adapter import StrictLoader

loader = StrictLoader()
try:
    config = loader.load_dict(oas_dict)
except OASSchemaValidationError as e:
    print(f"Validation failed: {e.issues}")

Component Mapping

OAS Component	Dapr Agents
Agent	AssistantAgent / ReActAgent
Flow	@workflow decorated function
LlmNode	@task with LLM call
ToolNode	@task with tool call
FlowNode	ctx.call_child_workflow()
MapNode	Fan-out with wf.when_all()
ControlFlowEdge	Branch routing via from_branch

Running the Examples

Prerequisites

• Dapr CLI installed and initialized
• An OpenAI API key in examples/_shared/dapr/components/secrets/

Run an example

cd examples/from_oas/04-agent-based-workflows
dapr run -f dapr.yaml -- python app.py

Examples are organized in two directions:

• examples/from_oas/ -- Import OAS specs to create Dapr Agents
• examples/to_oas/ -- Export Dapr Agents to OAS format
