Agent Framework Engineering
LangGraph is our default way to build agent workflows when execution needs to be predictable. It lets us express what happens next as a graph instead of a single prompt. Graphs are easier to test, reason about, and extend without destabilizing the system.
Why We Use a Graph Model
Most failures are coordination failures: loops, repeated tool calls, lost state, or untraceable decisions. A graph model enforces bounded nodes, explicit edges, and visible state.
How the Work Runs
Turn the Workflow into an Execution Graph
We map workflows into nodes such as intent capture, retrieval, planning, execution, verification, and escalation.
Design Streaming as Product Experience
We implement meaningful streaming updates for UI clarity.
Engineer State for Resume and Safe Retries
We define persistence rules, retry policies, and idempotent tool behavior.
Govern Tool Calls
Tools have predictable schemas and structured error handling.
Multi-Agent Only When Structurally Justified
Role separation is enforced through graph structure.
Observability and Evaluation From Day One
Node-level tracing and regression tests prevent workflow degradation.
What the Client Receives
Graph-Based Workflow Implementation
A graph-based workflow implementation with explicit nodes and transitions.
Durable State Management
Durable state management for long-running and resumable workflows.
Safe Retries and Resume Behavior
Safe retries and resume behavior that prevent duplicate side effects.
Governed Tool Patterns
Governed tool patterns with predictable schemas and error handling.
Role-Separated Coordination
Optional role-separated coordination for multi-agent scenarios.
Tracing and Evaluation Hooks
Tracing and evaluation hooks for observability from day one.
Practical Benefit
This approach treats agent workflows like software infrastructure: inspectable, testable, and maintainable.
- Inspectable, testable agent workflows
- Software-grade execution discipline
- Maintainable as the system evolves
Frequently Asked Questions
Graphs provide control over state transitions and failure handling.
Yes, through governed tool layers.
Yes, with durable execution and resume behavior.
Not always. Even simple workflows benefit from explicit state control.
