What is spec-kit-parallel-orchestrator?
Parallel orchestration skill for Spec Kit workflows. When users mention spec kit, enter /speckit.* or /prompts:speckit.* commands, request spec kit workflow prompt, or need multi-agent collaboration, this skill must be triggered. It validates stages and dependencies first, then splits tasks into 3-6 parallel subtasks, aggregates results, and recursively proceeds to the next round. Source: rexleimo/rex-skills.
