You are an operations lead and notice that a Project’s outputs have been drifting from...

Project output drift commonly occurs when persistent instructions, reference documents, terminology, policies, or expected formats no longer reflect the team’s current operating standard. Option C addresses the most direct and controllable cause by reviewing the Project’s instructions and knowledge sources before replacing the Project or changing models.

Anthropic explains that Project instructions define how Claude should behave and respond across chats in that Project. Documents uploaded to Project knowledge provide persistent context that Claude uses throughout those chats. If either component contains obsolete requirements, conflicting guidance, or superseded source material, Claude can consistently produce results that no longer meet the team’s expectations. The appropriate maintenance response is to compare instructions and knowledge against current standards, remove obsolete files, resolve contradictions, clarify requirements, and test the revised configuration with representative requests.

Option A is unnecessarily destructive before the cause has been diagnosed. Option B changes the model without correcting stale or conflicting instructions and therefore may preserve the underlying problem. Option D institutionalizes degraded output rather than correcting it. Reviewing and updating the Project configuration is the lowest-risk and most evidence-based first action.
