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 | $0.00091 | $0.01227 |
| Opus 5 | $0.00046 | $0.00613 |
| Sonnet 5 | $0.00018 | $0.00245 |
| Haiku 4.5 | $0.00009 | $0.00123 |
Grade A, and why
url-slug-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 12d 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.

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: URL Slug
Guides creation of SEO-friendly URL slugs for blog posts, articles, and content pages. Research on 11.8M Google results shows shorter URLs tend to rank higher; position #1 URLs average 50–60 characters.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Scope
- URL slug: The path segment after the base (e.g.,
ai-people-searchin/blog/ai-people-search) - Applies to: Blog posts, articles, guides, category pages, product pages
Best Practices
Length
| Guideline | Target |
|---|---|
| Slug length | Under 60 characters total (including path prefix) |
| Word count | 3–5 words |
| Principle | Shorter = easier to read, share, remember; less truncation in SERPs; see serp-features |
Example: "The Complete Guide to AI Search Engine for Finding People" → ai-people-search (3 words) or ai-search-finding-people (4 words), not ai-search-engine-finding-people-speed-discovery-outreach (9 words, 51 chars).
Format
| Rule | Do | Avoid |
|---|---|---|
| Separators | Hyphens (-) |
Underscores (_), spaces, periods |
| Case | Lowercase only | Mixed case (causes duplicate content) |
| Characters | Letters (a-z), numbers (0-9), hyphens | Special chars |
| Stop words | Remove when possible: the, a, and, or, to | Keep when needed: "how-to" |
Content
| Rule | Guideline |
|---|---|
| Primary keyword | Include near start; one focus per URL |
| Descriptive | Clear what page is about from slug alone |
| No keyword stuffing | One keyword mention is enough |
| No dates | Omit unless time-specific (news, annual roundups) |
Non-ASCII Characters
| Scenario | Rule |
|---|---|
| Accented letters | Convert to ASCII: é→e, ü→u, ñ→n, ç→c |
| Non-Latin scripts | Use UTF-8 percent-encoding if required; prefer ASCII for compatibility |
| Example | jalapeno not jalapeño; cafe not café |
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.
