I have started judging developer tools almost entirely on the first ten minutes, and I think the instinct is correct rather than lazy.
Not because the first ten minutes are the important part of the work — they obviously are not. Because they are the only part you can evaluate before committing, and because a tool that respects them is usually a tool built by someone who watched a real person use it.
What the first ten minutes are actually measuring
Time to first visible result. For a VFX tool, the moment something moves on screen that you caused. For a database library, the first successful query. Every step before that is unpaid setup, and users are entitled to resent it.
How many decisions you are forced to make while ignorant. This is the one most tools get wrong. Asking me to choose a project name, a package manager, a rendering backend, and a directory layout before I have seen the thing work is asking me to make four decisions with no information. Every one of them is a chance to get stuck, and none of them can be made well yet.
Whether the happy path is honest. If the quickstart works only because it skips the part that will bite me — no error handling, no build step, a demo asset that hides the asset pipeline — then it was marketing, not onboarding, and I will discover this at the worst moment.
The pattern I now look for
The best onboarding I have encountered lately does something slightly unusual: it hands you a prompt for your coding agent rather than a sequence of commands to run yourself.
That looked like a gimmick until I thought about what it actually optimises. A command list requires you to be correct at every step; a spec handed to an agent means the tedious, error-prone parts — scaffolding, installing the right peer dependency, wiring the loop — happen in one shot and produce a diff you can read. The verification is at the end, where it belongs, rather than distributed across eight steps you might mistype.
NixieFX's quick start is built this way: copy one prompt into whichever agent you use, and it sets up a Vite + TypeScript project, installs the runtime and its renderer peer, scaffolds an effect, exports the bundle, plays it in a scene, and tells you how to run the result. Ten minutes with one decision in it — which renderer — rather than six.
Two details in it are worth stealing regardless of your stack:
- The prompt names the packages explicitly. Removes an entire class of hallucinated dependency.
- The prompt links the docs and the machine-readable site index. An agent with the real reference stops inventing option names, which is the single biggest cause of confidently wrong scaffolds.
Where I would push back on my own heuristic
The obvious failure mode: optimising for the first ten minutes can produce a tool that is delightful to start and miserable at month three. Magic scaffolding, hidden configuration, a golden path that collapses the moment your project stops resembling the tutorial.
So the heuristic needs a second half. After the ten minutes, ask: can I see everything the tool did? If the scaffold is a readable diff and the configuration is a file in my repo, the fast start cost me nothing. If it materialised state I cannot inspect, I have borrowed against my own future.
Fast start, legible aftermath. Either one alone is a trap.
