Why it works
How detailed should requirements be?
Detail should align with the project's risk and complexity. Start with concise, testable statements and expand only where needed to prevent ambiguity.
Can this template cover API contracts?
Yes. Include endpoint definitions, request/response schemas, authentication schemes, error models, and versioning notes to ensure clear integration points.
How do I handle versioning and revisions?
Track changes in a dedicated Change History section and reference the current version from the header. Use concise commit-like summaries for each update.
