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-editing 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 12d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Copy Editing

Review existing copy without silently changing factual meaning. Preserve the submitted text, return revised copy, and account for every material edit with exact spans.

Read The References

Read review-contract.md for every request.

Read claims-and-evidence.md whenever copy contains factual claims, proof, prices, metrics, outcomes, comparisons, testimonials, certifications, guarantees, regulated statements, or user-supplied facts.

Read localization-review.md for every localization request, every China request, every Simplified Chinese asset, or any review where market, language, locale, or channel fit matters.

Confirm Review Scope

Review requires existing copy or clearly identified copy fields. Preserve the original verbatim before making any recommendation.

Do not turn editing into new positioning, audience research, competitor research, campaign strategy, or an invented offer. If those decisions are missing and would determine the copy, identify the required upstream work and return a bounded intake. Do not pretend it is a completed copy review.

Review authorization covers local analysis and artifacts only. CMS access, account access, live editing, publishing, deployment, sending, and contacting people are separate actions that require explicit authorization. Never imply that an external action occurred.

Record Context Separately

Record the audience, desired action, market, language, locale, channel or surface, constraints, approved voice, and supplied sources. Never infer market or channel from language. Missing evidence is unavailable, not a review failure.

Ask only for missing inputs that could materially change the edit. When a useful bounded review is possible, state assumptions and continue instead of requiring private data.

Select One Mode

Use the user's explicit mode when supplied. Otherwise select the narrowest mode that covers the request.

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.
