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 | $0.00081 | $0.01043 |
| Opus 5 | $0.00041 | $0.00522 |
| Sonnet 5 | $0.00016 | $0.00209 |
| Haiku 4.5 | $0.00008 | $0.00104 |
Grade A, and why
category-page-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 9d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pages: Category Pages
Guides e-commerce category page structure, content, and SEO optimization. Category pages organize products by attributes and drive 3x more organic revenue than product pages by ranking for broad, high-volume keywords.
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 product catalog and site structure.
Identify:
- Catalog: Product count, categories, subcategories
- Facets: Filters (size, color, price, brand, etc.)
- URL structure: Current hierarchy, parameter handling
Category Structure
Hierarchy
| Principle | Practice |
|---|---|
| Logical grouping | General -> specific (e.g., Furniture -> Bedroom furniture -> Beds) |
| User search intent | Match how users search (e.g., "bedroom furniture" vs "furniture") |
| Crawl depth | <=4 clicks from homepage; shorter paths improve indexing |
| Long-tail categories | Niche categories convert better (36% vs 11.5% for broad) |
URL Structure
- Subfolders:
example.com/shoes/sneakers,example.com/shoes/outdoor-shoes - Slugs: Descriptive, keyword-rich; lowercase; no stop words
- Avoid: Dates, timestamps,
/category/prefix - Breadcrumbs: Show path; help users and crawlers
Faceted Navigation (Filters)
Filters create many URL combinations (size + color + price). Manage to avoid duplicate content and crawl waste:
| Strategy | Use |
|---|---|
| Canonical | Point all faceted URLs to base category URL |
| robots.txt | Block faceted URLs from indexing if needed |
| nofollow | Add to internal links to faceted URLs |
| JavaScript | Keep filters client-side; single URL for category |
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.
