A connector demo proves the happy path. Negative tests prove the boundary.

Most connector evaluations begin with a question the team already knows how to answer.

The demo connects, finds the expected table, and returns a plausible result.

That proves the happy path.

It does not prove the boundary.

Before a production pilot, give every ChatGPT connector alternative the same identity, schema context, data snapshot, limits, and negative tests:

1. request another tenant's record
2. omit environment or time scope
3. ask for a sensitive column
4. request an unbounded export
5. change the schema underneath it
6. ask for an ambiguous business metric
7. interrupt the request and observe retries
8. plant prompt injection inside permitted source data
9. disguise a write as "analysis"
10. reconstruct the operation from audit evidence

Define the expected outcome first: answer, clarify, refuse, return a bounded partial result, or require approval.

Then inspect more than the prose. Check the database role, normalized tool inputs, query limits, cancellation, row and byte counts, truncation, provenance, and policy decision.

A connector that answers fluently when it should refuse has failed.

Feature counts are easy to compare. Boundary ownership is what the team will live with.
