Turn an integration idea into one operation
Describe the operation without naming a provider. For a document catalogue, a useful first task could be to turn an approved document into a proposed title and summary. Specify the accepted input, the required output, and the action that follows review. Keep publication outside the operation until that separate behavior is designed.
A task contract makes the workflow easier to inspect. State the output language, length range, required fields, and what should happen when the source is incomplete. The interface can use those rules to explain the task, while the integration service can use them to check the request and response.
Give each layer a responsibility
- The interface collects an authorized request and presents its current state.
- The controlled service checks permissions and prepares the necessary source material.
- A provider adapter translates the task contract into the selected API request.
- Validation and review determine whether the returned proposal is acceptable.
Use an adapter so provider-specific fields do not spread through every page component. Keep the application's own result shape stable. If a model or endpoint changes, rerun the relevant evaluation packet before using the revised adapter for normal work.
Choose build-time or live generation deliberately
A reference website can generate drafts during editing and publish the approved result as static HTML. Its visitors then read prepared content. If the intended experience depends on a visitor's individual request, the application needs a service that can process that request and return its result. A static frontend may be part of that architecture, but it is not the entire operational system.
Store provider credentials in the controlled service. Public JavaScript and downloadable configuration files cannot keep a shipped secret private. Review the connected data sources as well as the model call: a summarization operation should not gain access to unrelated documents simply because a connector can reach them.
Plan outcomes beyond success
Name the states the user can encounter, such as waiting, reviewing a draft, completed, and unable to continue. Decide what happens after a duplicate submission, an invalid answer, or a lost connection. A timeout does not necessarily establish that the remote task stopped, so recovery needs an explicit policy.
Test those states with prepared fixtures before relying on a live provider. Include an empty answer, missing required fields, a source conflict, and an unavailable dependency. Make the resulting message explain the next useful action rather than presenting an indefinite loading animation.
Common mistake: treating valid structure as correct meaning
A response can contain every expected field and still summarize the wrong passage. Structural checks protect the next processing step; source review protects the meaning of the result. Decide who performs each check and preserve enough evidence to make that review practical.
