Keep Knowledge Base Answers Within User Permissions

An access-aware retrieval test plan for a practical business AI workflow, with steps, an acceptance test, and a reusable prompt.

Deliverable: An access-aware retrieval test plan. Use this playbook when your team needs a repeatable operating decision with evidence that another person can inspect.

The business situation

A company assistant with general policies and restricted management documents. This is an illustrative scenario, not a reported client result. Start with a small approved sample and the actual constraints of your team.

The operating approach

Apply access filtering before retrieved text reaches the model. The answer must reflect the authenticated user’s permissions, including cached responses and any linked source passages.

Build it step by step

  1. Carry verified user identity into the retrieval service.
  2. Filter documents and passages using current access groups.
  3. Scope caches to permissions and source versions.
  4. Test access removal and links as well as normal search.

A concrete acceptance test

Ask a general employee for an executive-only document by exact title, then revoke access for a previously authorized user. Neither cached text nor source links should reveal restricted content.

Record the input, expected behavior, actual result, reviewer, and version tested. Repeat this case after a prompt, source, model, or integration change. Include the cases that failed in the next regression run.

The mistake to avoid

Asking the model to hide a restricted passage is too late if that passage already entered its context.

A reusable working prompt

Write a retrieval permission test plan covering identity, group membership, filtering, caches, revocation, source links, and audit evidence. Include denied-access cases.

Replace general descriptions with your approved process details. The prompt helps prepare an artifact; the process owner verifies the finished result before it changes a live workflow.

What to keep in the handoff

Save the accepted an access-aware retrieval test plan, its source versions, test evidence, unresolved questions, and a named owner. Set a review trigger tied to a meaningful business change, rather than leaving the pilot without maintenance.
