Structured Extraction Use this skill when extracting data that must match a specific JSON schema. Strategy by task type Simple query (single fact or small object) Search for relevant results. Scrape promising results with a targeted query. Build the result object and call formatOutput immediately. Single target research (one entity, multiple fields) Search for relevant URLs. Scrape to extract data — stay in the orchestrator unless you have many independent sources (roughly 5+) where parallel workers clearly help. Compile findings and call formatOutput. List of items (array in schema) Search/scrape to get the list of items. Are all requested details included in the list? Yes: Build the result and call formatOutput. No: If there are many items (roughly 5+), use spawnAgents so each worker gets the item and fields; otherwise fetch details sequentially in the orchestrator. Aggregate all results and call formatOutput.
