Discovery
The one-page problem brief
No code until the problem fits on one page a stranger understands.
5-point gate · 3 warning signs
Open Loop · product standards, published
A focused library for deciding, designing, building, testing, and shipping. Each published skill is complete enough to install—not a thin prompt or an unreviewed directory listing.

Focused flows
Small skill sets in useful order
Skills are complete
Every skill includes a trigger, instruction, failure signals, a quality gate, and a proof test.
Topics help you find
Topics are editorial navigation—not thin skills. Each one maps a real product question to authored skills.
Flows provide order
Focused flows sequence the smallest useful skill set for a specific job without flooding agent context.

Spec
Scope is a knife: one thin, end-to-end slice a user can finish.
5-point gate · 3 warning signs
Design
Empty, loading, error, success-after — designed before the happy path ships.

Design
One easing family, three durations, every animation has a job.

Design
Splash, onboarding, first value — the first minute is a designed product surface.

Design
Human, specific, exact — copy is designed, never placeholder.

Architecture
Choose the dullest tech that works, and record why in one page.

Architecture
Schema before endpoints — constraints in the database, not in hope.
5-point gate · 3 warning signs
Architecture
Rules live in pure functions; I/O stays at the edges; state machines are explicit.
5-point gate · 3 warning signs
Frontend
Tokens, motion discipline, and the 100ms rule — the production frontend bar.
5-point gate · 3 warning signs
Frontend
Numbers written down, measured on the production build, enforced at the gate.
5-point gate · 3 warning signs
Frontend
Keyboard, contrast, semantics, reduced motion — the floor nobody ships below.
5-point gate · 3 warning signs
Backend
Typed boundaries, one error envelope, no lying 200s.
5-point gate · 3 warning signs
Backend
Proven library, scoped queries, IDOR-tested — identity is not a place to be creative.
5-point gate · 3 warning signs
Backend
Integer money, idempotent webhooks, a ledger that reconciles to the cent.
5-point gate · 3 warning signs
Backend
Idempotent jobs, retries with backoff, dead letters someone actually reads.
5-point gate · 3 warning signs
Quality
Pure business rules tested at the edges — where the money bugs live.
5-point gate · 3 warning signs
Quality
Signup → core action → visible result, headless, on every merge.
5-point gate · 3 warning signs
Quality
Speed, trust, restraint, scale, voice — ask all five before approving.
5-point gate · 3 warning signs
Launch
404s, focus rings, OG cards, budgets — the unglamorous list that separates products from demos.
5-point gate · 3 warning signs
Launch
The money path emits events; errors page a human; one dashboard answers the question.

The system must get smarter with every failure — or you'll pay for the same bug twice.

Tear down the three best competitors before designing anything.

An AI agent is your fastest junior — brief it like one, verify it like one.

Design
Hierarchy, grid, and whitespace do the talking before color does.
5-point gate · 3 warning signs
Architecture
Each package is code you now maintain but didn't write — interview it first.
5-point gate · 3 warning signs
Frontend
Props speak the domain; variants are unions; composition beats configuration.
5-point gate · 3 warning signs
Frontend
Breakpoints come from content, and the widths between them must also work.
5-point gate · 3 warning signs
Quality
Agents produce plausible code — plausible is not correct.
5-point gate · 3 warning signs
Launch
One command boots it; a missing variable fails loudly; staging is production-shaped.
5-point gate · 3 warning signs
Discovery
Turn a fuzzy debate into one explicit choice, its evidence, trade-offs, and next move.
5-point gate · 3 warning signs
Discovery
Find the belief most likely to waste the loop, then test it before polishing anything else.
5-point gate · 3 warning signs
Discovery
Separate what happened from what was said, inferred, or merely hoped.
5-point gate · 3 warning signs
Spec
Prototype only enough reality to answer one costly product question.
5-point gate · 3 warning signs
Spec
Give an agent one bounded outcome, the context to act, and evidence that proves it is done.
5-point gate · 3 warning signs

Load only the skills the task needs, in an order that avoids conflict and context waste.
5-point gate · 3 warning signs
Architecture
Make done, blocked, unsafe, and not-worth-continuing observable before the loop starts.
5-point gate · 3 warning signs
Quality
Let a clean reviewer judge the artifact against the contract, not the builder's story.
5-point gate · 3 warning signs
Operate
Make the shared memory describe what now exists, why it changed, and how to verify it.
5-point gate · 3 warning signs
Operate
Hold one outcome for a month while evidence—not backlog volume—chooses each weekly move.

Need the system applied, not another resource list?
First Loop turns one hard product decision into working evidence within 48 hours of the agreed start.
