{"destructiveHint":false,"destructiveHintJustification":"Not destructive: checking a code cannot delete, overwrite, or irreversibly change any data, account, order, or external state.","idempotentHint":true,"openWorldHint":false,"openWorldHintJustification":"Not open-world: the answer comes only from MasaDeals' own bounded, checkout-tested dataset — the tool performs no web search or browsing and reaches no arbitrary external system.","readOnlyHint":true,"readOnlyHintJustification":"Read-only: the call only reads the stored record for one code — its status, constraints, and success stats — and returns it; it creates, changes, and deletes nothing."}
{"destructiveHint":false,"destructiveHintJustification":"Not destructive: a lookup cannot delete, overwrite, or irreversibly change any data, account, order, or external state.","idempotentHint":true,"openWorldHint":false,"openWorldHintJustification":"Not open-world: answers come only from MasaDeals' own bounded, checkout-tested dataset for named merchants — the tool performs no web search or browsing and reaches no arbitrary external system.","readOnlyHint":true,"readOnlyHintJustification":"Read-only: the call only looks up promo codes already held in the MasaDeals dataset and returns them; it creates, changes, and deletes nothing."}
{"destructiveHint":false,"destructiveHintJustification":"Not destructive: recording an outcome only appends telemetry — it never deletes or overwrites existing records, and it changes nothing at any merchant (no orders, accounts, payments, or cancellations).","idempotentHint":truefalse,"openWorldHint":false,"openWorldHintJustification":"Not open-world: the write goes only to MasaDeals' own telemetry store; the tool contacts no external system and takes no action on the public internet.","readOnlyHint":false,"readOnlyHintJustification":"Not read-only: the call appends one checkout-outcome event to MasaDeals' own telemetry store, updating the code's success statistics — that is why readOnlyHint is false. It is also not idempotent: each call records a new event, so repeating a call is not effect-free."}
