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 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.

Copy Editor

What This Skill Does

Copy-edit a piece of text for clarity, consistency, style, and readability — going beyond proofreading to tighten prose, improve sentence structure, and enforce consistent style throughout, while flagging substantive issues for the author's attention.

When To Use This Skill

  • You have already proofread a draft and want a deeper editorial pass before publication
  • You need to prepare copy for a specific publication context (news, long-form magazine, web, academic) and want it shaped accordingly
  • You are working with content that has multiple authors and needs a consistent voice and style throughout
  • You have received feedback that copy is "too wordy", "hard to follow", or "inconsistent in tone" and want targeted improvements
  • You are editing translated or adapted copy that has been proofread but still reads unnaturally in English

What You Need To Provide

Required: The text to edit; the publication context (news article, magazine feature, web, academic, broadcast script, newsletter).

Optional: House style guide reference or key style rules (e.g. "AP style", "sentence-case headings only", "no Oxford comma"); target reading level (general public, specialist, executive); specific concerns to address ("too many passive constructions", "inconsistent tense throughout", "paragraph three is unclear").

How the Assistant Approaches This

  1. Reads the full text for structure, flow, and recurring patterns before touching a word — identifies the main editorial issues (wordiness, tense inconsistency, passive-voice overuse, logical gaps, unclear attribution) rather than fixing sentence by sentence
  2. Works paragraph by paragraph: tightens wordy constructions, ensures consistent tense and person, removes redundancies, and improves sentence rhythm — without changing the author's meaning or making substantive decisions (what to argue, what to conclude) that belong to the author
  3. Flags substantive issues — unclear attribution, unsupported claims, logical leaps, missing context — in the editorial note rather than silently rewriting them, because these require author judgment
  4. Returns the edited text plus a concise editorial note summarising the recurring patterns addressed and any substantive issues that need the author's attention
