Start Here (Founder Brief)

Interviews you with five core questions and writes a founder-brief.md so every other GTM skill advises on your real business instead of generic textbook theory.

Marketing & SEOBeginner★ 304⑂ 30AI score 9/10Last updated: Sep 21, 2026

What it does

  • Asks five core questions one at a time, conversationally: what the product does in plain words, exactly who it's for, what users do today instead, stage and traction, and your single strongest provable asset.
  • Writes the answers to docs/gtm-cofounder/founder-brief.md in your project, the shared memory every other skill in the repo reads first.
  • Tags each answer [validated] (a real, non-friend user said it) or [assumption], and routes assumptions to the talk-to-users skill.
  • If run inside your repo, it does a bounded scan of README, package manifest, last ~15 commits and open issue themes so the interview starts warm, while explicitly treating the repo as input to critique, not gospel.
  • Deeper questions on positioning, buyers, pricing and distribution are pulled just-in-time by later skills, never front-loaded.

Who it's for

  • Dev-tool and SaaS founders who keep getting generic GTM advice from AI.
  • Solo founders and small teams tired of re-explaining company context in every prompt.
  • Early-stage teams that want a clear ledger of what's validated versus guessed.

Examples

  1. Run inside your project repo: the agent skims the README, says "here's how you currently describe it," challenges the framing, and drafts the brief.
  2. You answer "zero users interviewed": it records that plainly and flags talk-to-users as the top-priority next move.
  3. Weeks later a pricing skill runs: it asks only two extra questions about the economic buyer and appends them to the existing brief.
