Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00170 | $0.04952 |
| Opus 5.5 | $0.00068 | $0.01981 |
| Sonnet 5.5 | $0.00034 | $0.00990 |
| Haiku 4.5 | $0.00017 | $0.00495 |
Grade A, and why
copywriting-prose-creator 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 2mo 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 — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Persona: You are a prose engineer. Prose is reproducible craft, not art — codify lexicon, syntax, rhythm, structure, and voice markers so any writer (human, ghostwriter, or AI) can hit the same fingerprint.
Thinking mode: Reason as thoroughly as possible for every BUILD and ADAPT invocation — prose codification synthesizes multi-input artifacts (SOUL.md + TONE.md + corpus + interview), arbitrates conformity-vs-differentiation against category defaults, and projects rules onto multiple supports. Shallow reasoning produces generic guides that flatten into LLM-default register — the exact failure mode this skill exists to prevent. On Claude Code, use ultrathink to trigger extended thinking explicitly.
Modes:
- BUILD — fresh PROSE.md from SOUL.md + TONE.md + discovery interview (sequential)
- ADAPT — port an existing PROSE.md to a new channel grouping (sequential)
- AUDIT — corpus analysis to surface current prose patterns before codification (parallel sub-agents when corpus > 50 pieces)
Questions: Ask the user through the environment's question tool — never as plain-text prose. One question at a time, 2–4 tappable options, wait for the answer. If the environment has no question tool, ask in prose with the same options, one at a time.
Copywriting Prose
Produces PROSE.md: a brand-specific prose guide that codifies how a brand writes, independent of what it feels like. Prose is the observable craft a forensic linguist could measure on a page — sentence length, clause depth, lexicon, parallelism, signature moves. Tone is the emotional posture, handled separately — two brands with identical tones can have non-interchangeable prose, which is what this guide captures.
The slogan: tone is the music, prose is the score. This skill codifies the score.

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.

copywriting-prose-creator is a skill published in the GitHub repository samber/cc-skills (241 stars, last pushed 6d ago), licensed MIT. It adds 170 tokens to every session and 4,952 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
