What problem does it solve? Processing hundreds of independent items (files, records, texts) one at a time through an agent is slow and error-prone. This Skill fans work out to parallel subagents, batches rows automatically, and merges structured results back into a single table. ## Core Features & Use Cases - Parallel fan-out: Create a table from a glob pattern, file list, or pre-parsed records, then dispatch an instruction template across every row with bounded concurrency. - Structured output merging: A required JSON Schema constrains each subagent response, and schema properties become new columns on the table for chaining multiple passes. - Batching, filtering, and retry: Auto-batching caps dispatches, filters select row subsets, and failed rows can be reprocessed with an exists: false filter. - Use Case: Classify the sentiment of 200 customer feedback records from a JSONL file, then run a second pass that summarizes only the negative ones. ## Quick Start Use the swarm skill to classify the sentiment of every record in feedback.jsonl in parallel and show me the counts per sentiment.
