trellis-brainstorm

Invoke the brainstorming workflow to create a task directory and seed a prd.md file. The skill inspects repository evidence, asks one high-value question at a time, and converges on scope before any implementation begins.

Lightweight tasks produce prd.md with requirements and acceptance criteria. Complex tasks additionally require design.md for architecture and implement.md for an ordered execution checklist before task.py start is allowed.

Use it when requirements are unclear, multiple valid approaches exist, or the user describes a new feature or complex task. Simple, fully specified requests with no unresolved user-owned decisions can proceed without extended discovery.

No. Task-creation consent and general implementation intent authorize planning only. Implementation requires the final Brief review gate defined by trellis-task-brief, or explicit preauthorization for the unchanged final Brief.

Single-question turns keep decisions focused and ensure each answer updates prd.md before the next decision is computed. Questions must target user-owned product, scope, or risk decisions, not facts answerable from the repository.
