Codex Astro Starter - Build

The build

This build combines the skills below in a fixed order. Required skills are non-negotiable; optional skills add checks without changing the core path.

1
Codex Astro MVP
Runs the full build loop from planning to deployment
2
Validation Checklist
Turns the acceptance criteria into a checked gate
3
Visual Review
Captures screenshots at mobile and desktop widths for review
4
Link Checkeroptional
Catches internal 404s before the deploy is announced

Prerequisites

Node.js 20 or newer
A Git repository
A hosting account for the final step

Execution steps

1
Write the requirement list and out-of-scope list, and get it approved
2
Define the page tree and URL scheme
3
Set the visual direction as tokens
4
Scaffold Astro with TypeScript and the content collections
5
Build pages from the content model
6
Run type check, build, and link checks
7
Capture screenshots at 390 and 1440px and fix findings
8
Deploy the production build and re-run the smoke checks on the live URL

Acceptance checklist

Build passes from a clean checkout with the lockfile
No internal 404s in the link report
No horizontal overflow at 390px
Search indexes real content
Deployed URL passes the same checks as local
README documents run and deploy commands

Recovery steps

If the build breaks after install, reinstall from the lockfile

If content is hardcoded, migrate repeated markup into content collections

If the host fails, deploy the local production build artifact

What this build includes

One delivery skill that owns the whole loop, plus three small verification skills that attach checks to the end. The build is deliberately small: the checks are separate skills so they can be reused on any future site without re-reading the delivery skill.

When to use it

Use this as the default for any new static site. If the project later grows a backend or a team, replace the delivery skill, not the verification layer.
