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

copy-quality-gate 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.

Copy Quality Gate

The Law

COPY THAT CANNOT ANSWER "SO WHAT?" IS MARKETING FOR THE WRITER, NOT THE READER.
"It explains what we do" passes the author's test — the reader's test is "what does this mean for me?" and the reader leaves if the answer isn't in the first sentence.
Passing all three tests — "so what?", "who cares?", "why now?" — IS copy that earns attention.

When to Use

Trigger before:

  • Publishing any homepage, landing page, or hero section
  • Sending any email campaign or outbound sequence
  • Running any ad copy
  • Publishing any sales collateral or pitch deck

When NOT to Use

  • Internal documentation (no reader conversion goal)
  • Legal disclosures (accuracy and completeness are the goals, not engagement)
  • Help centre articles (utility copy — different standards apply)

The Three Tests

All three must pass. Passing two and failing one is a fail.

Test 1 — "So What?"

For every claim in the copy, ask: "so what does this mean for the reader?"

Apply the chain:

Claim: "Our AI automatically categorises support tickets."
So what? "You spend less time manually triaging."
So what? "Your team handles 3× more tickets without adding headcount."

The final answer in the "so what?" chain is the real claim. If it is not in the copy, the copy is incomplete.

Rule: If the "so what?" chain reaches a benefit the reader cares about in 2 steps or fewer, the claim is positioned correctly. If it takes 3+ steps, the copy is describing features, not benefits.

Failure pattern:

"We use transformer-based models with retrieval augmentation." So what? "It's more accurate." So what? "You get fewer wrong answers." So what? "You don't have to manually verify everything."

Three steps to reach the benefit — the copy is too feature-level. The copy should open with "fewer wrong answers you have to verify" and let the technology be a proof point, not the headline.

Test 2 — "Who Cares?"

Who specifically is this copy for, and does it speak to them?

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.
