What problem does it solve? Turning a rough 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 conversation, Update an existing brief against a change signal, or Validate a brief with cited, honest critique. - Coached discovery: Brain-dump friendly elicitation with web-research subagents, pushback on thin assumptions, and a choice between a fast path (assumption-tagged draft) or a coaching path (section-by-section). - Persistent workspace: Writes brief.md, addendum.md, and an append-only .memlog.md audit trail to a run folder, supporting stop-and-resume across sessions and headless (non-interactive) execution with JSON status output. - Use Case: A product manager with a pitch tomorrow invokes the skill, brain-dumps the idea, picks the fast path, and receives a polished 1-2 page brief with flagged assumptions plus an addendum of parked detail. ## Quick Start Ask the assistant to help you create a product brief for your product idea and answer its discovery questions.
