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 | $0.00096 | $0.01478 |
| Opus 5 | $0.00048 | $0.00739 |
| Sonnet 5 | $0.00019 | $0.00296 |
| Haiku 4.5 | $0.00010 | $0.00148 |
Grade A, and why
writing-quotation 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 5d 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 — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing Quotation
Formatting rules for quoting external sources inside a Markdown document. Other skills that produce sourced deliverables (survey, paper-details, and similar) reference this one.
1. Why quote the original
A summary alone does not let the reader judge whether the writer's reading of the source is correct. Placing the original alongside lets the reader cross-check the writer's interpretation against the source itself. Quotations and prose (the writer's own summary or interpretation) must stay visually and structurally distinct.
2. Quotations always go inside code blocks
Quote external sources inside a fenced code block, regardless of content type — prose, prompt templates, code, XML-tagged text, anything. Do not use the blockquote syntax (>).
3. Structure of a quotation block
A quotation block has the following shape.
- Opening code fence
- Original text
- One blank line
- Translation into the writer's working language (only when the source is in a different language)
- Closing code fence
- The source reference
[label (YYYY/MM), location]on the line immediately after the closing fence
Rules:
- Original and translation sit together inside the same code block.
- One blank line separates them.
- Do not insert a horizontal rule (
---) between original and translation. - Do not move the translation outside the code block. Do not put it in parentheses next to the original.
- The source reference belongs on the line after the closing fence as an independent line. Never inside the code block.
4. Examples
4.1 Same-language quotation
When the source and the writer share a working language, no translation is needed:
Composability is the property by which a system's behaviour is determined by the behaviour of its parts and the rules under which they are combined.
[example-handbook (2026/04), Section 2.1]
4.2 Cross-language quotation
When the source is in a language other than the writer's working language, place the translation as a separate paragraph inside the same code block:
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-quotation is a skill published in the GitHub repository mathbullet/skills (119 stars, last pushed yesterday), licensed MIT. It adds 96 tokens to every session and 1,478 once invoked, about $0.0005 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.
