Microsoft ships Agent Framework Declarative Workflows 1.0 — multi-agent orchestration moves from code to YAML

On July 23 Microsoft took agent-framework-declarative to 1.0.0 for Python, matching the already-stable .NET Microsoft.Agents.AI.Workflows.Declarative package. Workflows are authored in YAML — state and expressions via Power Fx formulas, conditions, loops and jumps, sequential and conditional agent routing, function tools, MCP and HTTP endpoints, human-in-the-loop approval pauses, and checkpoint/resume — then loaded as ordinary Workflow instances that execute identically to code-first ones. The pitch is reviewability: non-developers can audit orchestration logic without knowing the framework, which matters for regulated deployments where the routing graph is the compliance artifact.
