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-editor-assistant 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 8d 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 Editor Assistant

What This Skill Does

Reviews a draft article and returns a structured list of grammatical errors, style inconsistencies, and clarity issues — each flagged with a specific suggested correction and a brief rationale.

When To Use This Skill

  • You need a copy edit pass and don't have an editor available
  • You want a systematic pre-submission check before sending a draft to an editor
  • You're copy editing a piece written by someone else and want to work from a flagged list rather than reading through cold
  • You're working on a tight deadline and need to prioritize the most significant issues in a long draft

What You Need To Provide

Required: The draft text (or the section you want reviewed); the style standard you're writing to (AP, Chicago, Guardian, house style, or "general professional journalism"). Optional: Specific areas of concern (e.g., "I'm not confident about the punctuation in complex sentences," "check all hyphenation," "flag any passive voice that weakens a sentence"); word count of the piece (helps calibrate the depth of the review); whether this is a first draft (light touch) or a final draft (thorough line edit).

How the Assistant Approaches This

  1. Reads the full draft and categorizes issues into three tiers: Tier 1 (errors — things that are wrong by the stated style standard and must be changed), Tier 2 (inconsistencies — things that are used two different ways in the same piece and need to be made consistent), and Tier 3 (suggestions — things that are not wrong but would benefit from rewording for clarity or flow).
  2. For each flagged item: quotes the original text, provides the correction, and gives a one-line rationale citing the rule or reason (not just "fix this").
  3. Returns items in document order so the writer can work through them linearly. Ends with a brief summary: how many Tier 1, 2, and 3 items, and an overall verdict on the draft's readiness (ready to submit, needs one more pass, requires significant line editing).
  4. After the summary, provides a "Next Step" note: work through Tier 1 items first (in document order), run fact-check-prompt separately for any statistical or attributed claims, and confirm with the specific publication's house style guide if using general AP/Chicago standards

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.
