信息

The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.

Publish Site

Take a website, dashboard, or web app the user built (or you built for them) and put it online on infrastructure the user owns — GitHub Pages by default, Cloudflare Pages or Netlify when they need more. The discipline: preview locally for sign-off, version every deploy with a git tag, deploy through a provider ladder, verify the live URL with a real HTTP check, and keep rollback one command away.

This skill covers static sites and SPA build output (plain HTML/CSS/JS, or the dist//build/ folder from Vite/Next-export/Astro/etc.). It does not cover server-side runtimes — for throwaway serverless deploys with zero account setup, use the cloudflare-temporary-deploy optional skill instead.

When to Use​

Load this skill when the user asks to:

  • Put a site online — "publish this", "host this somewhere", "give me a link I can share"
  • Deploy a dashboard, report, portfolio, docs site, or prototype you just generated
  • Update an already-published site with new content (redeploy = new version)
  • Roll back a bad deploy to the previous version
  • Pick a host — they don't care where, they just want a URL

Prerequisites​

At least ONE authenticated provider CLI (check in this order):

  • GitHub Pages (default): gh auth status succeeds. Needs git too.
  • Cloudflare Pages: wrangler whoami succeeds (or CLOUDFLARE_API_TOKEN is set). Install: npm i -g wrangler or use npx wrangler@latest.
  • Netlify (fallback): netlify status succeeds. Install: npm i -g netlify-cli.

Plus:

  • A directory of static output to publish (site root or a dist//build/ folder). If the project needs a build step, run it first and publish the output directory, never the source.
  • For local preview sharing: cloudflared (optional — python3 -m http.server covers local-only preview).

How to Run​

All commands below run via the terminal tool from the site's project directory. The pipeline is always the same five moves:

  1. Build → 2. Preview for sign-off → 3. Commit + tag (version-before-deploy) → 4. Deploy via the provider ladder → 5. Verify the live URL with curl and report it.

Quick Reference​

Shareable previewcloudflared tunnel --url http://localhost:8080
Version a deploygit add -A && git commit -m "deploy: <what>" && git tag deploy-YYYYMMDD-HHMM
GitHub Pages (branch mode)git subtree push --prefix dist origin gh-pages

Cloudflare Pagesnpx wrangler@latest pages deploy dist --project-name <name>
Netlifynetlify deploy --prod --dir dist
Rollbackgit checkout <previous-tag> -- . && redeploy (or provider dashboard)
Verify livecurl -sS -o /dev/null -w '%{http_code}' <url> → expect 200

Procedure​

1. Build and preview locally​

Build if needed (npm run build, etc.) and identify the output directory. Serve it:

python3 -m http.server 8080 --directory dist

For a shareable preview link (user on another machine, or you want their sign-off before going live), open a quick tunnel in a background terminal session:

cloudflared tunnel --url http://localhost:8080

Give the user the https://*.trycloudflare.com URL and get sign-off before deploying. Kill the tunnel afterwards.

2. Version before deploy — no exceptions​

Every deploy must come from a git commit, so every deploy is reproducible and rollback is trivial.

git init 2>/dev/null; git add -A
git commit -m "deploy: <short description>"
git tag "deploy-$(date +%Y%m%d-%H%M)"

If the project already has a repo, just commit + tag. Never deploy uncommitted files.

3. Deploy — provider ladder​

Rung 1 — GitHub Pages (default: free, zero extra accounts if gh is authed):

gh repo create <name> --public --source . --push   # skip if repo exists
git subtree push --prefix dist origin gh-pages      # publish build output
gh api "repos/{owner}/<name>/pages" -X POST \
  -f 'source[branch]=gh-pages' -f 'source[path]=/'  # first time only

Site appears at https://<owner>.github.io/<name>/. If the site is the repo root (no build dir), push main and set Pages source to main instead of using subtree. For build-step projects that will redeploy often, prefer the official actions/deploy-pages workflow so pushes auto-publish.

Rung 2 — Cloudflare Pages (when the user wants a custom domain, redirects/headers, or Functions):

npx wrangler@latest pages deploy dist --project-name <name>

First run creates the project and prints the https://<name>.pages.dev URL. Custom domains attach via the Cloudflare dashboard (Pages → project → Custom domains).

Rung 3 — Netlify (fallback, or when the user already lives there):

netlify deploy --prod --dir dist

netlify deploy --dir dist (no --prod) gives a draft URL — useful as a second preview stage.

4. Rollback​

Rollback = redeploy a previous tag. Never hand-edit live output.

git checkout deploy-<previous> -- .   # or: git checkout deploy-<previous>; rebuild
# then rerun the same deploy command from step 3

Cloudflare Pages and Netlify also keep per-deploy history in their dashboards ("Rollback to this deploy"), which is faster when the CLI isn't handy.

5. Secrets and environment variables​

  • NEVER commit secrets, API keys, or .env files — they'd be public on Pages hosting. Check with git status before the first commit and keep .env* in .gitignore.
  • Runtime env vars belong in the provider's dashboard: Cloudflare Pages → Settings → Environment variables; Netlify → Site settings → Environment variables. GitHub Pages is static-only — no server env; anything embedded in the bundle is public by definition. Warn the user if their build inlines a key.

Pitfalls​

  • SPA routes 404 on GitHub Pages. Pages has no rewrite rules. Copy index.html to 404.html in the output dir (cp dist/index.html dist/404.html) so client-side routing recovers. Cloudflare Pages and Netlify handle SPAs via _redirects (/* /index.html 200).
  • GitHub Pages build lag. The site can take 1–10 minutes to appear after the first enable, and ~1 minute per subsequent push. Don't declare failure on the first 404 — poll curl a few times before investigating.
  • Case-sensitive paths. Pages hosts are case-sensitive Linux; a site that worked on macOS/Windows can 404 on assets referenced as Logo.PNG but committed as logo.png. Grep the HTML for mismatched casing when an asset 404s.
  • Project-page base path. https://<owner>.github.io/<name>/ serves under /<name>/ — absolute asset URLs like /app.js break. Use relative paths or set the build tool's base (vite build --base=/<name>/).
  • wrangler auth flow needs a browser. wrangler login opens OAuth; in a headless session prefer CLOUDFLARE_API_TOKEN (user creates it at dash.cloudflare.com → API Tokens) and never echo the token into logs.
  • DNS propagation on custom domains. New CNAMEs can take minutes to hours. Verify against the provider's default URL (*.pages.dev, *.netlify.app, *.github.io) first, then check the custom domain separately — don't conflate the two failures.
  • Deploying source instead of build output. Publishing the repo root when the real site lives in dist/ yields a directory listing or raw JSX. Always confirm the output dir contains an index.html.

Verification​

Do NOT report success from the deploy log alone. Before telling the user anything:

  1. curl -sS -o /dev/null -w '%{http_code}' <live-url> returns 200 (retry over ~2 minutes for a first GitHub Pages deploy).
  2. curl -sS <live-url> | head -30 shows the expected index.html content — optionally confirm markup with web_extract on the live URL.
  3. For SPAs, also curl one deep route (e.g. /about) and confirm it returns 200, not 404.
  4. git tag --list 'deploy-*' shows the tag for this deploy.

Then report the live URL to the user, along with the deploy tag they can roll back to.
