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 | $0.00095 | $0.00879 |
| Opus 5 | $0.00048 | $0.00439 |
| Sonnet 5 | $0.00019 | $0.00176 |
| Haiku 4.5 | $0.00010 | $0.00088 |
Grade A, and why
toc-generator 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 11d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Components: Table of Contents (TOC)
Guides TOC implementation for long-form articles, guides, and whitepapers. TOCs improve UX and SEO by enabling quick navigation and reducing bounce rates.
When invoking: On first use, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for content structure.
Identify:
- Content type: Blog article, guide, whitepaper, documentation
- Length: TOC most valuable for 1000+ word content
- Platform: Web, mobile, both
Placement Strategies
| Placement | Best For | Pros | Cons |
|---|---|---|---|
| After intro | Most articles | Natural flow; visible early | Can scroll out of view |
| Floating sidebar | Very long content | Always visible | More complex; mobile challenges |
| Collapsible | Long articles | Less intrusive | May be overlooked |
| Top of article | Mobile-first | Accessible on all devices | Takes space |
Technical Implementation
Heading Structure
- One
<h1>per page <h2>for major sections<h3>for subsections; avoid skipping levels- Headings >=15 characters for SEO
Jump Links
- Assign unique IDs to headings (e.g.,
id="keyword-optimization") - Use kebab-case for IDs
- Link TOC entries via anchor tags (
#section-id) - Descriptive anchor text; include target keywords naturally
Semantic HTML
<nav aria-label="Table of contents">
<ol>
<li><a href="#section-1">Section Title</a></li>
</ol>
</nav>
SEO Best Practices
| Practice | Purpose |
|---|---|
| Schema.org TableOfContents | Help search engines understand structure |
| Keywords in headings | Natural integration; avoid stuffing |
| Jump links in SERP | Google may feature TOC links; increases CTR; see serp-features |
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.
