Choose the stack around the job

Keep models, memory storage, connectors and interfaces replaceable. Company context, contracts and checked methods are the durable assets.

Use structured APIs and approved integrations. Connectors need scoped authentication, pagination, rate-limit handling and explicit failures. Keep secrets out of prompts, logs and generated artifacts.

Storage needs source references, access scope, correction and deletion. Semantic retrieval helps discovery; similarity is not the authority for current facts.

Pin dependencies and test provider changes on representative jobs. Fallbacks must preserve tool schemas and permissions. Check the destination before retrying an uncertain side effect through another provider.
