creative-copy

creative-copy is a skill for Claude Code from SerenecoTech/agent-skills. It costs 75 tokens per session (5,374 once invoked), scanned A, original, MIT.

A set of rules for writing copy where voice and natural flow matter more than strict scanning. It covers marketing pages, launch posts, blogs, newsletters, social posts, pitches, and personal email.

In plain words
What is it for?
Use it to write or revise landing pages, launch announcements, blog posts, newsletters, social copy, pitches, and voice-matched messages.
Why use it?
It helps avoid repetitive wording, uniform sentence patterns, and stock phrases that can make writing feel generated. It also supports matching a person's or brand's voice from examples.

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

creative-copy 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 2d 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 — 299 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Creative Copy

Write copy that reads the way a person's writing reads: varied rhythm, a position taken, and no repeated lexical patterns. Readers notice the patterns models fall into (uniform sentence length, stock vocabulary, tidy trinities, negate-then-assert beats) faster than any detector does, and once noticed the copy stops working. The rules below remove those patterns. They draw on CMU/PNAS stylometric research, Nielsen Norman Group style studies, GPTZero/Binoculars detection methodology, Wikipedia's AI Cleanup project, and professional copywriting frameworks.

Scope

This skill optimises for voice: text that reads as written by a specific person. It trades some scannability for that, so it is the wrong tool for documentation, runbooks, error messages, and agent instructions. The humanize skill decides which text gets this ruleset and which gets the documentation rulesets, and it owns the conflict rules between them. When a task mixes the two (a launch post that links to docs), this skill writes the post and the documentation rulesets write the docs.

Core Rules (Apply to All Writing)

1. Ban the AI Vocabulary

Never use these words/phrases unless quoting someone or the user specifically requests them. Full list with research backing in references/ai-tells.md.

Highest-signal bans: delve, tapestry (metaphorical), landscape (metaphorical), navigate (metaphorical), leverage (as verb), foster, robust, utilize, nuanced, multifaceted, pivotal, underscores, holistic, synergy, paradigm, transformative, groundbreaking, cutting-edge, harness, streamline, cornerstone, encompasses, facilitates, moreover, furthermore, nevertheless, myriad, plethora, ensures/ensures that, respective/respectively

Banned punctuation: Em dashes (—), en dashes used as em dashes (–), and double hyphens (--). Never use any of these. Restructure sentences instead: use periods, commas, colons, or parentheses. If a sentence needs an em dash to work, rewrite it so it doesn't.

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.
