A reliable event boundary
Verify incoming requests, capture them durably, and give every job an identity. Webhook events can be duplicated, delayed, or missed. A production workflow must tolerate those conditions rather than assuming every event arrives once and in order.
Reconciliation is the backstop: periodically compare your workflow state with the source and destination systems. It helps find missing work and actions that succeeded after a timeout.
Explicit data and permission boundaries
Document which data enters the workflow, where it is stored, who can see it, and when it is deleted. Keep secrets server-side and restrict credentials to the permissions each component needs.
Separate client environments and test data from production. For a browser-accessible database, enforce access in the database itself, not only in the interface. Test the denied cases as well as the successful ones.
Evaluation against real work
Create a stable set of representative examples, including difficult cases. Define the expected final state, then measure it. A successful tool call is not evidence that the right business outcome happened.
Use deterministic checks for exact requirements and expert review for subjective quality. If a model helps grade output, calibrate its judgments against people. Track changes in cost, latency, and quality before shipping a new version.
Bounded failure and recovery
Each integration needs a timeout, retry policy, maximum attempts, and an escalation owner. An error queue without a person responsible for it is simply another hidden backlog.
Write a replay procedure and a rollback or manual fallback. Explain how to stop the system safely and how to resume without duplicating actions. Practice recovery before an incident makes it urgent.
An operating handover
A complete delivery includes access ownership, architecture, mappings, evaluation cases, alert routes, retention settings, and an operator guide. Train both the people reviewing work and the person maintaining the system.
Agree the support arrangement explicitly: hours, response targets, changes included, third-party costs, and who is responsible for platform renewals. The workflow should remain understandable after the original builder leaves.
