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 | $0.00060 | $0.03444 |
| Opus 5.5 | $0.00024 | $0.01378 |
| Sonnet 5.5 | $0.00012 | $0.00689 |
| Haiku 4.5 | $0.00006 | $0.00344 |
Grade A, and why
clear-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 25d 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clear Writing
ISO 24495-1:2023 defines plain language by its outcome: wording, structure, and design so clear that the intended readers can easily find what they need, understand what they find, and use that information. Everything in this skill serves that outcome.
Two things about the standard shape how you should work:
- It focuses on how well readers can use a document, not on mechanical measures such as readability formulas. So the job is not "shorten sentences and swap hard words." Most of the work is deciding what these readers need and arranging it so they can act on it. Word choice is a small part: the International Plain Language Federation (IPLF) reports that only about 7% of the standard's roughly 485 ideas concern word choice.
- It applies to most written languages, and the IPLF describes it as language-neutral. Apply its guidelines through the conventions of the language you are writing in.
The four principles
The standard treats the principles as interdependent, not as a sequence: a text is usable when its content is relevant, findable, and understandable, and only evaluation shows whether it really is. The steps below follow the principles in working order; go back to an earlier step whenever a later one shows a problem.
| Principle | Reader outcome | Guidelines (clause) |
|---|---|---|
| 1 Relevant | Readers get what they need | 5.1.2 Identify the readers · 5.1.3 Identify the readers' purpose · 5.1.4 Identify the context in which readers will read the document · 5.1.5 Select the document type or types · 5.1.6 Select content that readers need |
| 2 Findable | Readers can easily find what they need | 5.2.2 Structure the document for readers · 5.2.3 Use information design techniques that enable readers to find information · 5.2.4 Use headings to help readers predict what comes next · 5.2.5 Keep supplementary information separate |
| 3 Understandable | Readers can easily understand what they find | 5.3.2 Choose familiar words · 5.3.3 Write clear sentences · 5.3.4 Write concise sentences · 5.3.5 Write clear and concise paragraphs · 5.3.6 Consider including images and multimedia · 5.3.7 Project a respectful tone · 5.3.8 Ensure that the document is cohesive |
| 4 Usable | Readers can easily use the information | 5.4.2 Evaluate the document continually as it is developed · 5.4.3 Evaluate the document further with readers · 5.4.4 Continue to evaluate readers' use of the document |
What ships with it
1 file 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.

clear-writing is a skill published in the GitHub repository buYoung/skills (21 stars, last pushed 15d ago), licensed MIT. It adds 60 tokens to every session and 3,444 once invoked, about $0.0002 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 2026-10-07.
