A final review for a landing page before it is shipped. It checks the page's strategy, copy, HTML, metadata, visuals, evidence, accessibility, trust signals, and clarity.

Use it to score a landing page, verify that its claims and visuals are supported, and decide whether it can ship or needs more work.

It catches pages that look finished but contain unsupported claims, unclear explanations, weak calls to action, or problems that make them unready to publish.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.00726
Opus 5.5	$0.00016	$0.00290
Sonnet 5.5	$0.00008	$0.00145
Haiku 4.5	$0.00004	$0.00073

Security

Grade A, and why

page-qa 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/eval-summary.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Page QA

This is the final gate. It exists because good-looking pages can still be strategically wrong, untrustworthy, or impossible to ship.

Required inputs

workspace/pages/[page-name]/strategy.json
workspace/pages/[page-name]/copy.md
workspace/pages/[page-name]/index.html
workspace/pages/[page-name]/meta.json
workspace/pages/[page-name]/visuals/index.md
workspace/pages/[page-name]/visuals/manifest.json when present
references/anti-slop.md

QA dimensions

Score each 1-10 unless pass/fail is more appropriate.

1. Mechanism preservation

is the unique mechanism visible and understandable?
does the page explain why this works?
did aesthetics overpower explanation?

2. Proof discipline

are all stats, testimonials, logos, guarantees, and claims provenance-tagged?
is anything non-shippable still presented as real?

3. Trust cue preservation

were critical trust conventions preserved?
were category-legitimacy cues kept intact?

4. Copy sharpness

specificity
fluff control
objection coverage
CTA clarity

5. Visual fidelity

correct preservation class use
no fake precision where exactness was required
no obvious artifacts
provider fallback history is reflected honestly in metadata when relevant

6. Build quality

responsive structure
contrast
semantics
focus states
alt text

7. Anti-slop compliance

no banned patterns
anti-slop used without overriding brand fidelity

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
