AI Coding best practices: engineering conventions for production
Field-tested AI Coding practices from production, avoiding the common anti-patterns.

Quick answer
What is the difference between Claude Code and Cursor rules file formats?
Both use CLAUDE.md or .cursorrules to pin hard constraints (stack, package manager, prohibitions). The file formats differ slightly — do not mix them.

In-depth analysis
AI Coding (Vibe Coding) uses agents like Claude Code, Cursor, and v0 to assist development: first encode the hard constraints in a rules file, then let the model produce runnable code inside that controlled context. Production engineering conventions revolve around "single source of truth + explicit boundaries", steering clear of the common anti-patterns.
# .cursorrules / CLAUDE.md — hard constraints for the coding agent (context tightening)
stack: Astro + Tailwind v4 + Cloudflare Pages (output: static)
package: pnpm only, lockfile committed, --frozen-lockfile in CI
secrets: always use the placeholder <CF_API_TOKEN>, never paste real values into code or conversation
comments: no Chinese in code or comments
# One-command scaffold
npx create-astro@latest my-site --template minimal --no-install
cd my-site && pnpm install && pnpm devAI Coding Best Practices · Key takeaways
- Config centralized in a single source
- CI uses --frozen-lockfile
- Secrets are placeholders, never real values in code
- Docs and code live in separate places
FAQ & pitfalls
How do I keep AI-generated code from poisoning build cache?
Put rules and lockfiles under version control; CI uses --frozen-lockfile. Generated output goes to an isolated branch so it never pollutes main branch builds.

What readers are asking
Questions that keep coming back in reader feedback, already answered.
- 01
Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.

Why is my custom Tailwind v4 brand colour not applied?
Colours must be declared in @theme (for example --color-brand). A missing @tailwindcss/vite plugin, or a leftover v3 config, makes bg-brand silently render nothing.

Why are _headers / _redirects not taking effect?
Both files must sit at the root of the output directory (dist/); anything under src/ is never uploaded. A purely static project should not add _worker.js either — that gives up the zero-cold-start advantage.
