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 | $0.00062 | $0.00751 |
| Opus 5 | $0.00031 | $0.00376 |
| Sonnet 5 | $0.00012 | $0.00150 |
| Haiku 4.5 | $0.00006 | $0.00075 |
Grade A, and why
internal-links 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 8d 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.

SEO On-Page: Internal Links
Guides internal linking strategy for SEO: crawlability, link equity distribution, and user navigation.
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.
Scope (On-Page SEO)
- Internal links: Contextual links; descriptive anchor text; related posts; hub pages
- Breadcrumbs: Implement for large sites (e.g. ecommerce); see breadcrumb-generator
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for site structure and key pages.
Identify:
- Site structure: Hub pages, pillar content, supporting pages
- Orphan pages: Pages with no or few internal links
- Priority pages: Pages that need more link equity
Best Practices
Link Structure
| Principle | Guideline |
|---|---|
| Depth | Important pages within 3 clicks from homepage |
| Orphan pages | Avoid; ensure every page has at least one internal link; see site-crawlability for technical detection and crawl issues |
| Hub-to-spoke | Link from hub/pillar pages to cluster articles; topic cluster structure |
| Contextual | Place links in relevant body content, not just footers |
Anchor Text
| Principle | Guideline |
|---|---|
| Descriptive | Use anchor text that describes the target page |
| Variation | Avoid over-optimization; use natural variation |
| Keyword | Include target keyword when natural |
Placement
| Location | Use |
|---|---|
| First paragraph | Primary link to related content |
| Body | Contextual links throughout |
| Related/Recommended | End-of-article links |
| Navigation | Key site sections |
Common Issues
| Issue | Fix |
|---|---|
| Orphan pages | Add internal links from hub pages or navigation; site-crawlability for technical audit |
| Too many links | Focus on most important; avoid link stuffing |
| Generic anchors | Use descriptive "learn more about X" instead of "click here" |
| Broken links | Audit and fix 404s; see site-crawlability for technical audit |
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.
