In the past we blipped the tailored service templates pattern, which helped organizations adopting microservices by providing sensible defaults to bootstrap new services and integrate them seamlessly with existing infrastructure. Over time, however, code drift between these templates and existing services tends to grow as new dependencies, frameworks and architectural patterns emerge. To maintain good practices and architectural consistency — especially in the age of coding agents — we’ve been experimenting with anchoring coding agents to a reference application. This pattern guides generative code agents by providing a live, compilable reference application instead of static prompt examples. A Model Context Protocol (MCP) server exposes both reference template code and commit diffs, enabling agents to detect drift and propose repairs. This approach transforms static templates into living, adaptable blueprints that AI can reference intelligently — maintaining consistency, reducing divergence and improving control over AI-driven scaffolding as systems evolve.
