Apify Generate Output Schema

Generates the three schema files Apify Actors need to display their output properly in the console: dataset_schema.json, output_schema.json, and key_value_store_schema.json. It analyzes your Actor's source code to understand what data actually gets pushed, finds existing type definitions to reuse instead of duplicating them, and checks other Actors in your repo to match their conventions. The workflow is thorough: it searches for all pushData calls, ensures every field is marked nullable (because scrapers break), enforces that additionalProperties true appears at every level, and anonymizes examples. Useful when you're publishing an Actor or need to update schemas after changing your output structure. Saves you from reading the Apify schema docs and hand-writing JSON.
