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

quick-check 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quick Check

The fast quality check. 4 items. Takes under a minute. Good enough for "can I show my friend?"

The 4 Checks

1. Does It Load?

Open every page in the browser. Check:

  • No blank/white pages
  • No console errors (open dev tools → Console)
  • No visible "Error" or "500" or "404" on the page
  • Content actually renders (not just a loading spinner forever)

✅ Pass: all pages show content ❌ Fail: any page shows an error, stays blank, or shows a crash screen

2. Does The Main Thing Work?

Identify the PRIMARY user action (form submit, button click, navigation flow) and do it:

  • If there's a form → fill it out and submit. Does it save? Does it show confirmation?
  • If there's a CTA button → click it. Does it go somewhere?
  • If there's a login → try logging in. Does it work?
  • If it's a portfolio → do images load? Can you navigate between pages?

✅ Pass: the main action completes successfully ❌ Fail: the main action breaks, shows an error, or does nothing

3. Mobile?

Resize the browser to 375px width (iPhone SE). Check:

  • Text is readable (not overflowing or cut off)
  • Navigation is usable (hamburger menu works, or links are tappable)
  • No horizontal scroll
  • Content isn't overlapping

✅ Pass: looks usable on a phone ❌ Fail: layout is broken, text overflows, navigation is unusable

4. Can Everyone Use It?

Quick accessibility scan — not a full audit, just the obvious stuff:

  • Images have alt text (not empty)
  • Text is readable against its background (good contrast)
  • Buttons and links have clear labels (not just an icon with no text)

✅ Pass: basics covered ❌ Fail: images missing alt text, unreadable text, or unlabeled buttons

Report Format

All Good

✅ Quick check — looks good.

1. ✅ All pages load fine
2. ✅ Form submits and saves correctly
3. ✅ Looks good on mobile
4. ✅ Accessibility basics covered

Ready to show someone! 

Issues Found

Quick check — found 1 thing:

1. ✅ All pages load fine
2. ✅ Form submits correctly
3. ⚠️ Mobile: the headline text is too wide and gets cut off on phones

This won't break anything, but it'll look off on smaller screens.

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.
