Claudeagent and Claudeagentg1t.page builds know the framework a project is built with, from its package's dependencies and config files: Vite (and React, Vue, Svelte, Solid or Preact on it), Astro, Next.js with `output: 'export'`, SvelteKit with the static adapter, Nuxt by `nuxi generate`, React Router and Remix in SPA mode, Gatsby, Docusaurus, Eleventy, Angular, Create React App, Hugo, Jekyll and mdBook are each built with their own command and served from the folder they write, read from their config where it moves it. A Cloudflare adapter's Worker deploys as a Workers project with no Wrangler config of the project's own: Astro's, which now writes its config for wrangler in `.wrangler/deploy/config.json` (as `@cloudflare/vite-plugin` does, and that is read too), SvelteKit's `.svelte-kit/cloudflare/_worker.js`, and OpenNext's with a `wrangler.jsonc`; a site's `_worker.js`, `_routes.json` and what `.assetsignore` lists are never uploaded, and a written config's empty binding lists are no longer warned about. A framework set up to need a server (Next.js without a static export, Astro's server output, SvelteKit's auto or node adapter, a server-rendered React Router or Remix app) fails before anything is installed, saying what to change, in place of "found nothing to serve". The project's Build command and Output directory still win. The build's log names the framework, the finish report carries it as `framework` (which the deployments service ignores for now), and `g1t-runner detect` and the `g1t/detect` action output it. What deploys has a table of every framework, and the detect action's README lists them.

README.md

g1t/detect

Says what a g1t.page build of the checkout would find, without building or deploying anything: the same rules g1t/deploy builds with.

steps:
  - uses: actions/checkout@v5
  - id: detect
    uses: g1t/detect@v1
  - if: steps.detect.outputs.kind == 'none'
    run: echo "::error::Nothing here would be served."
  - if: steps.detect.outputs.framework == 'hugo'
    run: echo "A Hugo site, served from ${{ steps.detect.outputs.output-dir }}"
  - if: steps.detect.outputs.install != ''
    run: ${{ steps.detect.outputs.install }}

Inputs

InputDefault
root-dirThe checkoutWhere the project is in the checkout.
build-commandNoneA build command of your own, as g1t/deploy takes it.
output-dirNoneAn output folder of your own, as g1t/deploy takes it.

Outputs

Output
kindworkers (a wrangler.jsonc, wrangler.json or wrangler.toml, or a framework's Cloudflare adapter), static (a site a build writes), html (the files as they are) or none (nothing to serve, or a framework set up to need a server).
frameworkThe framework it is built with, from the table below. Empty when there is none.
installHow dependencies are installed, from the lockfile: npm ci, pnpm install --frozen-lockfile, and so on, and bundle install for Jekyll. Empty when there is nothing to install.
buildWhat builds it: your command, the package's build script (npm run build), the framework's own command, or wrangler deploy --dry-run for Workers. Empty when nothing does.
output-dirThe folder served, relative to the project (. for the project itself): yours, a Workers project's assets directory, the folder the framework writes, or the first of dist, build, out, public, _site, .output/public that exists. Empty when a build has yet to write it, as for a Cloudflare adapter's Worker.

When kind is none because of how a framework is set up, such as a Next.js app without output: 'export', the step's log says what to change.

What deploys has each one's build command. Your build-command and output-dir win over what is detected.

It runs g1t-runner detect, found or downloaded as g1t/deploy finds it.
