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 | $0.00109 | $0.00863 |
| Opus 5 | $0.00055 | $0.00432 |
| Sonnet 5 | $0.00022 | $0.00173 |
| Haiku 4.5 | $0.00011 | $0.00086 |
Grade A, and why
authoring-documentation 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 2d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation (*.md)
You MUST review @projects/site/src/docs/internal/guidelines/documentation.md before making any documentation changes.
When to Use This Skill
- Creating or updating markdown documentation files
- Working with 11ty templates in the documentation site
- Using or creating Eleventy shortcodes
- Writing API documentation or component guides
- Updating internal guidelines or developer documentation
- Fixing Vale prose-linting errors in markdown or JSDoc
Key Principles
- Frontmatter Required: All documentation files must include proper frontmatter with title and layout
- Eleventy Shortcodes: Use built-in shortcodes for common patterns (code examples, callouts, etc.)
- Clear Structure: Use proper heading hierarchy and table of contents for long documents
- Code Examples: Include working code examples with proper syntax highlighting
- Cross-References: Link to related documentation and guidelines using proper paths
Prose Linting (Vale)
How Vale Runs
- Pre-commit (via lint-staged): automatically lints staged non-test
*.tsand*.mdfiles - CI:runs as part of
pnpm run ci - Manual:
pnpm run lint:valefrom the repo root (pass specific files as args to narrow scope)
Rule Sets by File Type
*.md:Vale, Google, write-good, Elements (full rule set)*.ts:Vale, write-good, Elements (no Google rules or spelling checks to reduce noise on code identifiers)*.examples.ts:same as*.tsplus three summary rules:SummaryStyle,SummaryActionable,SummaryGerund
Common Errors and Fixes
| Rule | Trigger | Fix |
|---|---|---|
Google.Latin |
e.g., i.e. |
Use "for example," "that is" |
Google.Passive |
Passive voice | Rewrite in active voice |
Google.Quotes |
Punctuation outside quotes | Move commas/periods inside quotation marks |
Elements.Branding |
nvidia, Nvidia |
Always use NVIDIA |
Elements.Terminology |
web component |
Use Web Component / Web Components |
Vale.Spelling |
Unknown term | Add the term to config/vale/styles/config/vocabularies/Elements/accept.txt |
Elements.SummaryStyle |
Weak openers like "This example demonstrates" | Lead with what the example does or when to use it |
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.

authoring-documentation is a skill published in the GitHub repository NVIDIA/elements (83 stars, last pushed 2d ago), licensed Apache-2.0. It adds 109 tokens to every session and 863 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.
