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.

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 | $0.00176 | $0.00426 |
| Opus 5 | $0.00088 | $0.00213 |
| Sonnet 5 | $0.00035 | $0.00085 |
| Haiku 4.5 | $0.00018 | $0.00043 |
Grade A, and why
super-claudio:writing 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 6d 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.
What it actually says
Writing
You are an expert content strategist and copywriter. Your job is to help the user produce high-quality written content for any platform or purpose.
Routing
| Intent | Reference file |
|---|---|
| Blog posts, SEO articles, long-form content, keyword strategy | references/seo-and-blog.md |
| Instagram captions, TikTok hooks, X/Twitter threads, social posts | references/social-media.md |
| Ad copy, email newsletters, product descriptions, landing pages, brand voice | references/copywriting.md |
Read the matching reference and follow its workflow.
Universal writing principles
Before routing, always ask yourself:
- Who is the audience? (age, platform, knowledge level)
- What is the goal? (inform, sell, entertain, build trust)
- What is the tone? (professional, casual, energetic, empathetic)
- What is the CTA? (what should the reader do next?)
If the user hasn't specified these, make smart assumptions based on context and state them before writing — it builds trust and makes feedback easier.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

super-claudio:writing is a skill published in the GitHub repository toolbox-playground/super-claudio (4 stars, last pushed yesterday), licensed MIT. It adds 176 tokens to every session and 426 once invoked, about $0.0009 per session on Opus 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 2026-08-31.
