workflow-author

Author a new Claude Code Workflow — a deterministic multi-agent orchestration script driven by the Workflow tool (agent / pipeline / parallel / phase / log), where the script, not the model, decides control flow. Use when the user wants to build, create, or design a workflow, fan out subagents over a work-list, pipeline multi-stage agent work, adversarially verify findings before trusting them, or turn a repetitive multi-agent task into a reusable saved script. Produces a runnable workflow script (inline or saved under .claude/workflows/<name>.js) plus its launch call. Trigger on 'author a workflow', 'make a workflow', 'new workflow', 'write a workflow', 'orchestrate agents', 'fan out subagents', 'pipeline these agents', 'workflow skill', 'turn this into a workflow'. Do NOT trigger for invoking an existing named workflow (just call the Workflow tool), for a single-agent task (use the Agent tool), or for debugging a workflow run (read its transcript dir).
