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 5.1 | $0.00110 | $0.01983 |
| Opus 5.5 | $0.00044 | $0.00793 |
| Sonnet 5.5 | $0.00022 | $0.00397 |
| Haiku 4.5 | $0.00011 | $0.00198 |
Grade A, and why
tab-accordion 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 today.
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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Components: Tab & Accordion
Guides tab and accordion implementation for organizing content without excessive vertical space. Two layout patterns: vertical accordion (FAQ-style, stacked) and horizontal tabs (how-to style, side-by-side). Both improve UX by reducing scroll; SEO impact depends on implementation and content placement.
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.
Layout Patterns
| Pattern | Layout | Best for | Example |
|---|---|---|---|
| Vertical accordion | Stacked; expand/collapse one at a time | FAQ, Q&A, long lists, objection handling | "How do I return?" → answer below |
| Horizontal tabs | Side-by-side labels; one panel visible | How-to steps, product specs, pricing tiers, comparisons | "Step 1 | Step 2 | Step 3" or short action labels (see howto-section-generator—labels should match H2 intent, not contradict a fixed “N steps” title) |
Mobile: Vertical accordion works well on small screens (natural scroll). Horizontal tabs can feel cramped—consider accordion, dropdown, or full-width tab bar that scrolls.
SEO: Is It Friendly?
Google's position: Google indexes and ranks content inside tabs and accordions fully; hidden content receives full weight (confirmed since 2016 mobile-first indexing). Gary Illyes: "we index the content, its weight is fully considered for ranking."
Practical nuance: Some tests show always-visible content outperforms hidden content in rankings. Reserve tabs/accordions for secondary content; place primary, keyword-critical content in visible areas.
| Content type | Placement |
|---|---|
| Primary / ranking-focused | Visible above fold; not hidden |
| Secondary / supporting | Tabs, accordions acceptable |
| FAQ answers | Accordion OK; first item expanded by default; see faq-page-generator |
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.
