name: market-scan description: Refresh the user's competitive and market context. Re-scan named rivals and the category for what changed since the brief was written (rebrands, repositioning, new entrants, pricing shifts, renamed categories) and update docs/gtm-cofounder/founder-brief.md and the roadmap with anything that moves positioning. Use on a cadence, or whenever a competitor rebrands, a new tool appears, or the user senses the market has shifted under them.
> Positioning rots. The competitor you sized up six months ago has since rebranded, raised, repriced, or renamed the category. This is the habit that keeps your brief honest about the world outside it.
**Use this when:** a rival just rebranded or repositioned, a new tool is getting attention in your space, your `docs/gtm-cofounder/founder-brief.md` competitor answers are more than a quarter old, or you just have the feeling the ground moved and your messaging is answering last year's market.
`research-the-market` is the first full pass on the market: venues, launches, the problem in public, rivals, openings. This skill is the refresh after that, focused on what changed.
Your `docs/gtm-cofounder/founder-brief.md` captured the market as it was the day you wrote it. Markets don't hold still. A scan re-checks the outside world against your brief and surfaces the deltas: what changed, and which changes actually threaten or help your positioning. Most don't matter. The scan's job is to find the two or three that do, not to produce a competitor spreadsheet.
Changes worth acting on:
