Content Developers are generally asked to develop a certain update with a particular goal (for example "a new, low-budget Herblore training method") and are more or less free to fill it in as they please and devise its mechanics, narrative, and gameplay, so long as it remains in accordance with the design. Content Developers code their own content and implement it accordingly.
