What problem does it solve?
It structures an early product discovery conversation so your inputs become schema-aligned docs/discover-notes.md that /product-spec can reliably transform into a full spec, whether you are starting fresh or changing an existing system.
Core Features & Use Cases
- Greenfield or brownfield discovery: Automatically adapts the question flow based on project markers to handle new products and meaningful system changes.
- Resumable, phase-based facilitation: Detects prior sessions in
docs/discover-notes.md and resumes from the next unfinished phase without replaying completed work.
- Brownfield inheritance and delta gating: Scans existing artifacts (like
docs/product-spec.md, docs/architecture/, and docs/work/) to inherit stable baseline elements and ask only what is changing.
- Optional reference material scan: Lets you select evidence from
docs/reference/ and threads it through phases as check-against context, not silent authority.
- Safety via schema checkpoints: Follows
references/product-spec-schema.md for the required checkpoint format so downstream generation is consistent.
Quick Start
Run the discover skill with your idea inline, for example: /discover a lightweight inventory app that suggests reorder items from current stock.
