The code is becoming hard to maintain
Every feature costs more than the last. Juniors write "the way they're used to," seniors spend reviews on style instead of the domain.
Methodology
Use Case Pattern
An architectural methodology: a language-neutral contract plus Java, Python, and Node bindings
↓ consists of
Knowledge
Standards
1,472 rules with codes R-AGG-X4, PG-T-013 across 17 style guides.
Contract
Specifications (spec-as-code)
16 sections in the repo alongside the code. Section depth is chosen to match the service's maturity level.
Depth
4 maturity levels
The team picks a level to fit the task — from MVP to hexagonal.
Implementation
Reference libraries
The reference Java binding, open-source, Apache-2.0. Python and Node bindings are assembled from their ecosystems.
↓ implemented by bindings
Binding · ready
Java
Spring Boot, jOOQ, reference libraries. Articles are in Standards.
Binding · ready
Python
FastAPI, SQLAlchemy, Pydantic. Style guide and ucp-py-* skills.
Binding · ready
Node
NestJS, TypeORM, class-validator. Style guide and ucp-node-* skills.
Binding · in progress

↓ outcome for the team
Services are written consistently and fast. Every PR is reviewed against one and the same standard — automatically, without hiring another architect.
Who benefits
A backend team of 5+ (Java/Kotlin, Python, or Node), a product built for years ahead. If even one symptom feels familiar, it's worth talking.
AI writes code, but there's no consistency
Three Claude sessions give three different solutions. A year later — ten services in ten styles.
Specs go stale before they're even approved
The analyst writes, the developer rewrites, and a month later no one knows where the truth is.
