What problem does it solve? Turning a raw product idea into a clear, honest, right-sized product brief is hard: assumptions go unexamined, key context stays in the founder's head, and drafts either pad or miss what downstream teams need. This Skill coaches users through creating, updating, or validating a brief so the output reflects their own thinking. ## Core Features & Use Cases - Three intent modes: Create a new brief from scratch, Update an existing brief against a change signal, or Validate a brief with honest, line-cited critique. - Coached discovery: Conversational brain-dump facilitation with web-research subagents, pushback on thin assumptions, and a choice between a fast path (assumption-tagged draft) and a coaching path (section-by-section). - Persistent workspace: Each run writes brief.md, an optional addendum.md, and an append-only .memlog.md audit trail, supporting stop-and-resume across sessions and headless (non-interactive) execution with JSON status output. - Use Case: A founder preparing an investor pitch describes their idea; the Skill surfaces gaps, drafts a 1-2 page brief with an addendum for deeper detail, and logs every decision for later PRD work. ## Quick Start Ask the assistant to help you create a product brief for your product idea and answer its discovery questions.
