mapreduce
Fan-out tasks to multiple AI providers or agent instances in parallel, then consolidate the results into a single high-quality output. Use for parallel planning, multi-implementation code generation, and debug consensus across Claude subagents and external CLI providers.
Why this skill is useful
Adds a comprehensive orchestration framework for parallel task execution and result consolidation, enabling new capabilities in multi-agent collaboration.

What this skill does
MapReduce Skill Skill ID: mapreduce Purpose: Fan-out tasks to multiple providers/agents, then consolidate results Category: Orchestration Overview The MapReduce skill enables parallel task execution across multiple AI providers or agent instances, followed by intelligent consolidation of results. This produces higher-quality outputs by leveraging diverse model strengths and cross-validating findings. Architecture Key Constraint Subagents cannot spawn other subagents. All orchestration happens in the main thread. Workers and reducers are subagents that operate on files. Use Cases 1. Parallel Planning Fan out planning task to multiple providers with different strategic biases: See: cookbook/parallel-planning.md 2. Multi-Implementation Generate the same feature with multiple models, pick best: See: cookbook/multi-impl.md 3. Debug Consensus Get multiple diagnoses of a bug, verify and select best fix: See: cookbook/debug-consensus.md Available Reducers Reducer Agent Path Purpose --------- ------------ --------- plan-reducer agents/orchestration/reducers/plan-reducer.md Consolidate plans code-reducer agents/orchestration/reducers/code-reducer.md Compare/merge code debug-reducer agents/orchestration/reducers/debug-reducer.md Verify fixes Provider Integration Claude Subagents (via Task tool) External CLI Providers (via spawn skill) See: skills/spawn/agent/cookbook/ for detailed CLI patterns. …
