Functional Error Handling
Fin<T> replaces exceptions. Business failures are types, not thrown objects — composable, predictable, and compile-time safe.

6 specialized AI agents guide you through a 7-step workflow from requirements analysis to testing. At each step, design documents and compilable C# code are generated simultaneously. Designed for .NET teams practicing enterprise DDD, teams bridging the gap between development and operations, and architects systematically adopting functional DDD architecture.
Exceptions as business logic Business rule success and failure are handled through exceptions, making flow unpredictable and composition impossible.
Dev language ≠ Ops language Logs lack business context — operators cannot understand domain events from infrastructure metrics alone.
DDD remains theoretical Aggregate boundaries, Value Objects, and Specifications are discussed but never enforced in code.
Functional Error Handling
Fin<T> replaces exceptions. Business failures are types, not thrown objects — composable, predictable, and compile-time safe.
Built-in Observability
ctx.* context propagation delivers business fields to all 3 pillars (Logging, Tracing, Metrics) automatically.
DDD Building Blocks
Entity, AggregateRoot, ValueObject, Specification, DomainEvent — enforced by architecture tests, not just conventions.
AI-Guided Development
6 specialized agents (product-analyst, domain-architect, application-architect, adapter-engineer, test-engineer, observability-engineer) generate code that compiles.
