Document an unfamiliar code path

The job

A readable walkthrough of a specific feature's control flow and data flow.

Before you start

Ask me for: Relevant source files, entry points, and the question you want answered. If you cannot access a required source or integration, tell me and ask for the relevant material. Do not pretend to have checked it.

Instructions

1. Confirm the scope, inputs, and constraints with me before starting. Ask only for information needed for this task.
2. Trace calls using actual code references. Explain inputs, outputs, state changes, and error handling. Separate verified behavior from assumptions and list what would need runtime testing.
3. Separate confirmed information from assumptions. Include source links and dates for facts that may change.
4. Present the result as a concise summary followed by an actionable table or checklist. Include unresolved questions and suggested next steps.
5. Let me review the result. Ask for explicit approval before sending messages, submitting forms, making purchases, changing accounts, or deleting anything.

Done looks like

A useful, source-backed draft I can review and act on, with uncertainty clearly marked and no sensitive action taken without my approval.
