Use the agreed brief and accessible source files to create [OUTPUT]. Start with the smallest version that satisfies its acceptance checks. Follow any documented source workflow in order, adapting only where necessary and labeling your additions.
Do the authorized work with your available tools. Save actual deliverables where supported and show their locations. If file creation is unavailable, provide the complete usable content in a supported form and label that limitation. Do not substitute a description of what you would create for the creation itself.
Keep source material intact. Do not spend money, publish, send messages, or change access unless that action is already authorized. Stop only for essential missing inputs or decisions that require my judgment. Report completed work, outputs, and open issues.
