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 | $0.00069 | $0.00506 |
| Opus 5 | $0.00034 | $0.00253 |
| Sonnet 5 | $0.00014 | $0.00101 |
| Haiku 4.5 | $0.00007 | $0.00051 |
Grade A, and why
writing-revision 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 13d 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 — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing Revision
Use this skill to improve any kind of writing while preserving the writer's intent, factual claims, audience fit, and useful voice.
Workflow
- Read
references/writing.md. - For technical writing, docs, changelogs, UI copy, onboarding text, help text, or product explanations, extend the base workflow with
references/technical-writing.md. - Identify the writing situation before editing:
- format
- audience
- goal
- desired tone
- constraints or facts that must stay fixed
- Rewrite in passes:
- purpose and reader fit
- structure and flow
- paragraph shape
- sentence clarity
- voice, tone, and rhythm
- final polish
- Preserve facts, names, dates, quotes, commitments, technical terms, legal meaning, and personal details unless the user explicitly asks to change them.
- For technical writing, apply the technical extension after the base writing pass: technical precision, executable examples, exact UI labels, identifiers, and product truth take priority over smoothness.
Revision Rules
- Make the main point easy to find.
- Match the structure to the reader's job and the piece's purpose.
- Keep one dominant idea per paragraph or section.
- Prefer concrete language over vague abstraction.
- Improve rhythm without making the writing sound generic.
- Preserve the writer's voice when revising existing text.
- Cut filler and repeated ideas.
- Avoid em dashes. Use space-padded hyphens (
-), colons, semicolons, commas, or sentence breaks when they fit better. - Remove cliches, stock idioms, and familiar figures of speech unless the user explicitly wants that register.
- Add transitions only when they clarify the relationship between ideas.
- Do not make claims stronger than the source supports.
- Do not over-polish personal, emotional, or opinionated writing until it loses its human texture.
- Do not rewrite technical detail into vagueness or change commands, paths, labels, version numbers, routes, or identifiers unless they are wrong.
What ships with it
5 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.

writing-revision is a skill published in the GitHub repository hugobowne/show-us-your-agent-skills (67 stars, last pushed 1mo ago), licensed MIT. It adds 69 tokens to every session and 506 once invoked, about $0.0003 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 2026-08-30.
