One line in. One build brief out.

WHAT IT SOLVES

Coding agents are great, but getting them to build the right thing first try? You'll burn through 5 rounds of 'actually, also add…' before anything ships.

WHY IT'S INTERESTING

★ Product taste

It doesn't write code. It writes the prompt that writes the code.

Most AI coding tools compete on code generation. 1ShotGen bets the bottleneck isn't generating code — it's specifying what to build. It outputs a structured brief: tech stack, file structure, edge cases, done criteria. Then you hand that brief to your agent of choice. Clean separation of concerns.

★ Real craft

The output catches things you'd forget

It doesn't just rephrase your idea into longer paragraphs. It decomposes into files, edge cases, and tech stack decisions — you can see the counters (TOKENS, FILES, EDGE CASES) ticking up in the UI, suggesting real scope analysis, not template fill-in-the-blank.
