  • Know when to stop tweaking the prototype and start hardening — a clear prototype-vs-production decision framework, plus a catalog of how vibe-code actually breaks (and how to recover)
  • Make AI output you can trust: TDD with AI, a real code-review checklist, and how to catch it when the AI's own tests are wrong
  • Close the security holes AI quietly leaves — prompt injection, the AI attack surface, common vulnerabilities by language, and secrets / auth / supply-chain
  • Ship and run it like a product team: release engineering at AI velocity, CI, observability, and cost control — so it survives real users
  • Scale past one script — prompt → workflow → agent decisions, production MCP with safe tool access, and multi-agent patterns that don't add chaos

It's the only place those community perks live.

Common questions about Track Packs.

Does a Pack unlock the other tracks too?+

No — a Track Pack is for the one track you buy, and it unlocks that track's premium modules for life. If you want all four tracks, don't buy multiple packs — subscribe to Substack Experimenters, which unlocks every track plus the live community.

What's the difference between Vibe Coder, Field Guides, and Vibe Management?+

Vibe Coder is for builders writing or shipping AI-powered code — the technical track. Field Guides is the Second-Brain-to-Claude-Cowork track for anyone whose job is information work (IT, ops, consulting, marketing, legal, healthcare). Vibe Management is the running-AI-in-production track — for eng leaders, platform teams, and solopreneurs whose agents are the product.

Why is it $45?+

$45 is the launch price for the first 100 buyers — after that, Track Packs go to $149. Either way it's one-time: you own that track's modules for life, no recurring charge. (See the launch-sale note above for what else is bundled during launch.)

What's in the launch sale?+

Two things, for a limited time (first 100 buyers): (1) Track Packs are $45 instead of $149, and (2) every Pack includes 1 year of Experimenters access free — that's all four tracks plus the live community (the Experimenters Discord, daily office hours, and the weekly build call). After launch, Packs return to $149 and Experimenters goes back to a separate subscription. You keep your track's modules for life either way.

What's the 7-day trial?+

Pick one of the three tracks, get magic-link access to its premium modules for 7 days. No card, no auto-charge. One trial per email, lifetime. Modules only — the live community (Discord, office hours, build call) is Experimenters-only. After 7 days, access reverts to free; your progress carries over if you buy.

Track Pack vs Substack Experimenters — which do I want?+

A Track Pack is a one-time $45 purchase that unlocks one track's premium modules for life — no subscription, no community perks. Substack Experimenters is a subscription that unlocks all four tracks plus the live community: the Experimenters Discord, daily office hours, and the weekly build call. Buy a Pack for the track you live in; subscribe to Experimenters if you want everything.

Can I get my team on this?+

Yes. Two options. (1) Each team member buys their own Pack — they each get that track's modules for life. (2) Book a guided implementation — we sit down with your team, pick 2 workflows, and wire them into your existing AI stack (Claude Cowork, Microsoft 365 Copilot, GitHub Copilot, ChatGPT).
