Notes from building things with Claude Code
Short write-ups of problems and fixes hit while building things with Claude Code. A running log of trial and error across Hugo, GitHub Pages, Docusaurus, Vercel, and more.

Claude Cloud Routine vs. GitHub Actions cron: they look the same but you manage them differently
·322 words·2 mins
A repo with no visible cron workflow isn’t proof there’s no automated publishing. The schedule and generation logic can live entirely outside the repo, on Claude’s side.
GitHub Pages custom subdomains: static/CNAME alone is never enough
·216 words·2 mins
The repo can have its CNAME file and the Pages API can have its cname field set — but without an actual DNS record at the registrar, certificate issuance stays blocked.
One subdomain = one GitHub Pages repo — running many sites off a single account
·300 words·2 mins
It’s easy to assume GitHub Pages only really serves one thing per account. In practice it’s the CNAME file that decides routing.
Commit message language is a per-repo decision — and the automation template needs updating too
·225 words·2 mins
An English-facing site had commits piling up in Korean. Switching new commits to English seemed simple, until one easy-to-miss spot turned up.
Adding an LLM feature to a static site without ever putting a token in the browser
·314 words·2 mins
Two options came up first — an API key in localStorage, or a Cloudflare Worker proxy — and neither was it. A GitHub-issue trigger pattern was requested instead.
npx skills add installs to ~/.agents/skills, not ~/.claude/skills
·173 words·1 min
The install command exits clean and the files exist on disk, but the skill still won’t show up in the session — check the path first.
Hugo Hextra theme: in-content relative links must end in .md
·221 words·2 mins
An extensionless relative link like lab renders fine locally but 404s under GitHub Pages’ pretty URLs.
If Vercel deploy fails for no obvious reason, check for uppercase in the folder name
·216 words·2 mins
A project folder named CTI trips up both create-next-app and vercel deploy on name validation.
