Return to the original acceptance conditions
Compare the observed outputs with the pilot brief rather than replacing the goal after testing. Did the assistant answer the supported tasks, preserve source qualifications and handle missing evidence appropriately? Record what remains unresolved. A useful demo on a different task is not completion of the original one. Equally, a small cosmetic defect should not be described as a total failure when the important conditions are satisfied.
Use narrowing as a real option
If one source area performs poorly, consider excluding it and keeping a clearly described smaller remit. Verify that the interface does not still imply broad coverage. Narrowing is not a way to hide failures; preserve the held cases and the reason they are outside the current scope. It can be a practical response when a limited set of maintained documents provides useful answers and the rest is not ready.
Treat absent usage honestly
No genuine reader use does not establish that the assistant is good, bad or profitable. Check availability and appropriate measurement before interpreting silence. If the controlled cases pass but the audience has not encountered the feature, record a technical result with an untested value hypothesis. Do not manufacture chat activity or repeatedly expand the scope simply to create a more impressive report.
Stop when the cost of confidence is too high
If important errors remain hard to detect, source updates cannot be verified or no one can maintain the review process, ordinary documentation may be the better route. Retain the useful source improvements and evaluation record even if the tool is removed. A pilot that prevents an unsuitable subscription can still be valuable. The decision should serve readers, not defend the time already spent on installation.
Where the safety evidence stops
This guide draws on LangChain: evaluation datasets and reference answers. Merchant-controlled records describe the provider’s own capabilities, terms or standards; they do not independently validate those claims. These records do not establish independent confirmation of the product claims.
Verify any current price, plan limit, label direction, compatibility rule, or commercial term that would materially change the decision. The dated source ledger shows the underlying records so this conclusion can be checked and updated.
