What I build with

The gain is not autocomplete, it is that a whole task can be handed over with its context. The cost is that it will confidently do the wrong thing thoroughly, so anything it touches still gets read. This site's audit found four defects it had introduced and eleven it had documented incorrectly.

Structured output, so the model returns JSON and the script assembles the file. It never writes frontmatter and `draft: true` is set in code, which means a model that decides to publish itself cannot. See scripts/draft-post.mts.

Version 16 moved enough that most tutorials you find are wrong for it — `PageProps` is generated rather than imported, which cost this repo three days of red CI before anyone read the error properly.

v4 is CSS-first: there is no tailwind.config.js, and every tutorial that tells you to edit one is describing v3. Colours live in an @theme block.

The reason is comments. A content file you edit six months later needs to explain itself, and JSON cannot. Typos fail the build naming the file and field.

Plain Markdown for the most part; the components are worth it for two things only, a callout and a video embed.

Previews are what makes the drafting pipeline reviewable — a machine-written post renders as a real page before anyone decides whether to merge it. A broken content file fails the build and the last good deploy keeps serving.

Row-level security is the whole game and it is easy to get subtly wrong: an audit of REON found 183 SECURITY DEFINER functions callable by the anonymous key, every one of them running as the database owner. Postgres, not Supabase, but Supabase makes the surface reachable from a browser.

It has its own deterministic bar type, which is what lets a replayed chart be byte-for-byte the chart that was traded. Without that, backtests are fiction.

One thing worth knowing before you rely on it: an event produced with the repository's own GITHUB_TOKEN does not start another workflow. A job that opens its own pull request has to run its own checks, or the pull request arrives with nothing having run against it.
