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

proofreader 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 10d 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.

Proofreader

What This Skill Does

Proofread a piece of text and return it with all spelling, grammar, punctuation, and typographical errors corrected — preserving the author's voice and intentional style choices throughout.

When To Use This Skill

  • You are doing a final check before publishing an article, caption, press release, or broadcast script
  • You need to verify that translated or adapted copy has not introduced language errors during revision
  • You are reviewing user-generated or community-submitted content before it goes live
  • You have written a draft quickly under deadline and want a clean error pass before sending to an editor
  • You need to check headlines, subheadings, pull quotes, or captions that are often missed in a full-document proofread

What You Need To Provide

Required: The text to proofread.

Optional: Language variant (British English, American English, Australian English — defaults to British English if not specified); house style notes (e.g. "Oxford comma: yes", "spell out numbers under ten", "capitalise 'Government' when referring to the UK Government"); whether to flag style choices for review rather than correcting them silently.

How the Assistant Approaches This

  1. Reads the full text for meaning before making any corrections — understanding the author's intent, register, and deliberate style choices (sentence fragments for effect, informal voice, rule-breaking for emphasis)
  2. Makes a correction pass for spelling errors, grammatical mistakes, punctuation errors, and typographical issues (doubled words, missing words, transposed letters), distinguishing between genuine errors and intentional stylistic decisions
  3. Returns the corrected text in full, followed by a numbered change log listing every correction made — the original, the corrected version, and the reason — so the author can review and accept or reject each change individually

Output Format

Two sections:

Corrected text — the full text with all errors fixed. No annotations or markup in the text itself unless track-changes format was requested.

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.
