• [nitpick] Consider linking to or briefly describing the structure of AirdropEvent so readers know which fields are included and which can be ignored.

Runner.ts processes events of type "any", which are basically events of type "AirdropEvent" with some additional fields, and passes the events to the function. You can ignore the additional fields.

• Indent secret properties two spaces under the - _secrets_ list item so they render as a nested sublist in Markdown.

    - _service_account_token_: Required. A **string** representing the DevRev authentication token for Airdrop platform

• TypeScript array syntax should be AirdropEvent[] instead of []AirdropEvent to correctly declare an array of events.

async function run(events: []AirdropEvent): void;
