Separate configuration from business logic
Start with ownership boundaries. Keep connection settings, authentication, request construction, and error translation in a replaceable adapter rather than scattering provider assumptions through business logic. Obtain the confirmed base URL, model identifier, and protocol from support before creating environment configuration; do not infer a hostname or path. Compatibility with a protocol does not imply identical optional parameters, tool behavior, or error formats. Document the fields your application actually uses and the behavior when a required feature is unavailable. Review configuration changes with the same care as application changes because a small routing change can alter data handling and results.
Make failures understandable
Reliability means understanding failure, not pretending failure cannot occur. Set connection and overall task deadlines, and distinguish no result, partial output, and confirmed completion. If a stream disconnects, do not present partial text as a validated final answer or automatically authorize downstream writes. Offer an understandable recovery path such as retrying later, preserving a draft, or handing the task to a person. A retry policy must consider duplicate execution and uncertain completion; resubmitting a request is not automatically harmless. Keep user-facing messages useful while limiting operational detail that could expose credentials, sensitive content, or internal infrastructure.
Release through layered acceptance
Validate configuration and a minimal request first, then representative tasks, concurrent workloads, and failure scenarios before introducing production traffic gradually. Observe request identifiers, outcome categories, latency distributions, and usage trends while minimizing collection of raw content. Identify who triages incidents, how a problematic feature can be disabled, and how the previous configuration can be restored. These are integration controls a customer can design; they are not a claim about UBTL service commitments or implemented backend features. Keep support confirmations, test evidence, and acceptance criteria together so later upgrades can repeat the same checks rather than relying on memory.
