Read ../general/preview-template/SKILL.md, then adapt it to Codex:
- Inspect project manifests and
AGENTS.mdfor the canonical preview command. - Start long-running dev servers in a background exec session when possible.
- If the default port is occupied, choose another port and state it.
- Keep the server running only if the user needs to try it or a later verification step needs it.
- End with the actual local URL.
Do not start a server for plain HTML when opening the file directly is enough, unless browser APIs or module loading require HTTP.
