A pre-deployment checklist that tests whether a web project is ready to publish. It checks pages, forms, sign-in, mobile layouts, and other release concerns.

In plain words
What is it for?
Use it before deployment to check routes, forms, authentication, mobile behavior, and the other checks included in the release checklist.
Why use it?
It finds problems that may not be obvious from looking at a page, such as failed form submissions, broken protected-page redirects, or layouts that overflow on phones.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

before-you-ship scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Before You Ship

The full 9-item checklist that runs before deployment. Called automatically by the shipper agent. Can also be triggered manually.

The 9 Checks

1. All Pages Load

Visit every route in the app. Each must render without:

  • Console errors
  • Blank pages
  • Uncaught exceptions
  • Missing components

2. Forms Save Correctly

Submit every form with test data. Verify:

  • Data appears in Supabase (or whatever storage is used)
  • Success confirmation shows
  • Form clears or redirects after submit
  • Submit button shows loading state (prevents double-submit)

3. Auth Works (if present)

If the project has login:

  • Visit a protected page while logged out → should redirect to login
  • Log in with valid credentials → should reach the protected page
  • Sign out → should return to public page
  • Visit login while already logged in → should redirect to dashboard

Skip if no auth is set up.

4. Mobile Layout

Check at 375px (phone) and 768px (tablet):

  • No horizontal overflow
  • Text readable without zooming
  • Navigation usable (hamburger, bottom nav, or responsive links)
  • Forms fillable (inputs not cut off, keyboard doesn't hide submit button)
  • Images scale properly

5. Images Load

  • No broken image icons
  • All images have reasonable file sizes (warn if any > 1MB)
  • All <img> tags have alt attributes (even if empty string for decorative images)

6. No Dead Links

  • Click every link on every page
  • No 404 pages
  • No links that go nowhere or point to #
  • External links open in new tab

7. Accessibility Basics

Not a full WCAG audit — just the essentials:

  • All images have alt text
  • All interactive elements (inputs, buttons, icon links) have visible labels or aria-label
  • Color contrast meets WCAG AA minimum (4.5:1 for text, 3:1 for large text)
  • Focus indicators visible when tabbing through the page
  • Page has a <title> tag

8. Page Speed

Run a basic performance check:

  • Page loads in under 3 seconds
  • No massive unoptimized images
  • No blocking scripts
  • Fonts load without visible flash

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
