walkaround

scan_app creates a scan and returns a receipt id, while get_receipt retrieves a receipt by id. Their purposes are sequential and non-overlapping, so an agent can easily choose the right tool.

Both tools follow the same snake_case verb_noun pattern (scan_app, get_receipt), with no deviations or mixed conventions.

Only two tools are provided, which is borderline thin for a server that could also support listing receipts or checking account balance. However, each tool is necessary for the core scan-and-retrieve workflow.

The tools cover the main lifecycle of scanning an app and reading its receipt. Minor gaps exist, such as no way to list past receipts or manage token credit, but these are not critical for the primary use case.
