The rule

A developer must read all API policy files before writing any external API code.

This prevents mistakes like too many retries or bypassing the main coordinator. The developer is responsible for intellectual property risks when using paid services.

Before writing any external API code, a developer must read specific policy files. These files include rules for starting a session, handling retries, and using the central API coordinator. Following these rules prevents errors. Errors could include sending too many requests or bypassing important controls.

A developer needs to integrate a new payment system using an external API. Before writing any code, the developer reads the API policy files. The files state that the developer must not retry failed transactions more than three times. The files also explain how to use the central API coordinator for all requests. The developer follows these rules. This prevents the system from flooding the payment API with too many retry attempts.

How do I make sure my AI prompt changes work correctly?

When changing a prompt, check three things. First, ensure every user choice leads to a specific instruction, not a general one.
