Core principle
Typesafety absolutism: full-stack TypeScript with a single source of truth and inference over
hand-written types; typesafety is a core, non-negotiable axiom

Principles
- Typesafety absolutism — full-stack TypeScript with a single source of truth and
inference over hand-written types; typesafety is a core, non-negotiable axiom
[T3 intro]
[types & Next.js]
- "Bleed responsibly" — reach for bleeding-edge tools only in reversible places where you
can afford the cost [T3 intro]
- Build-your-own when unhappy — Ping, UploadThing, T3 Chat all born from dissatisfaction
with incumbents [t3dotgg]
- Optimize for delivery + iteration, not architecture cosplay — speed of shipping, DX, and
maintainability over ceremony [2023 tech]
- Defaults are opinions — create-t3-app's shipped choices (Next.js, tRPC, Tailwind,
Prisma/Drizzle) are his stated best practices, encoded as an executable starter

Workflow
"Bleed responsibly" — reach for bleeding-edge tools only in reversible places where you can
afford the cost [T3 intro]. Optimize for delivery and
iteration, not architecture cosplay: speed of shipping, DX, and maintainability over ceremony
[2023 tech]. Build-your-own when unhappy with incumbents —
Ping, UploadThing, and T3 Chat were all born that way
[t3dotgg]. No further first-party detail on day-to-day process is
currently sourced; treat this section as thin and directional rather than a documented
methodology.
See references/stack.md for the stack and references/workflow.md for workflow detail.
Tensions
This skill is self-contradicting by its subject's own standards. Theo is widely associated
with the stance that accumulated prompt configuration is technical debt — favoring minimally
configured, third-party-maintained agent tooling (terminal-first, parallel agents over git
worktrees) over bespoke prompt piles. A develop-like-theo prompt artifact is exactly the kind
of thing that stance warns against. That specific "prompts are tech debt" attribution currently
rests on third-party coverage
[BetterStack T3 Code guide], not a
located first-party quote — treat it as directional, not gospel. Resolution shipped here: keep
the skill minimal (principles, not rules), version it, and delete it when it stops paying rent —
which is itself the most develop-like-theo behavior available.
Want a reviewer/pair persona in Theo Browne's voice? See personas/theo-developer.md — it's reference material. Claude Code users can copy it to .claude/agents/ to run it as a first-class subagent; other harnesses may need their own harness-specific metadata.
