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

antislop-copywriting scanned grade A with 1 finding 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 1mo 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.

Anti Slop: Rules for AI Coding Agents. Copy & Text skill

Part of the antislop system. Read together with antislop.md (the core). This skill deep-dives the copy and text concern: headlines, CTAs, tone, value propositions, and the patterns that make AI-written prose easy to spot. It references core rules by number and never duplicates or renumbers them. Load it when the task writes or edits marketing copy, product copy, landing-page text, or any prose meant for people to read.

How to use this skill

  • Load together with antislop.md whenever the task is copy or text work. The core holds the mechanism (the purpose test, the three tiers, the Delivery Gate) and the hard bans (R-02, R-15, R-16, R-17, R-18, R-36, R-38). This skill holds copy-specific depth that the core does not.
  • Every pattern has the same shape: The pattern, Why it reads as AI, Before (the slop), After (the fix), with the governing core rule cited as R-XX.
  • Two rules apply to everything below:
    • Never invent facts (R-17, R-36, R-38). A rewrite adds no fact, name, number, date, quote, or citation that is not in the source text or supplied by the user. Specificity comes from the source or the user, not from the rewrite. If a sentence needs real detail to work, ask for it or write the plain version without it.
    • Do not over-sterilize. Avoiding AI patterns is half the job. Copy with no voice is as obviously machine-made as copy full of AI tells (R-37). When a user supplies a voice, keep it.
  • The Delivery Gate in the core remains the gate. The "Copywriting Skill Checklist" at the end of this file is the copy-specific supplement to run alongside it.

Tone & Voice

Empty AI Vocabulary

  • The pattern: verbs and abstract nouns stacked to sound impressive without saying anything: unlock, elevate, empower, delve, showcase, testament, landscape (abstract), journey, robust, game-changer, next-level, seamless, cutting-edge, revolutionary.
  • Why it reads as AI: these words appear far more often in machine-written text. They signal intent to impress, not intent to inform, and they are the fastest way to mark a page as AI-generated.
  • Before:

    Unlock the power of seamless collaboration to elevate your team's journey to the next level.

  • After:

    Work with your team in one shared space.

  • Rule: R-16 (buzzwords), R-36 (no fabricated claims).
