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 | $0.00084 | $0.01612 |
| Opus 5 | $0.00042 | $0.00806 |
| Sonnet 5 | $0.00017 | $0.00322 |
| Haiku 4.5 | $0.00008 | $0.00161 |
Grade A, and why
seo-helpful-content scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **URL** — WebFetch (fallback `curl -sL`), or How it starts
The opening of the file, as written. The whole thing — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Helpful Content Gate (People-First Self-Assessment)
Implements Google's own self-assessment from https://developers.google.com/search/docs/fundamentals/creating-helpful-content. Walk EVERY question with YES / NO / PARTIAL + one line of evidence from the content. Google also suggests getting an honest assessment from people unaffiliated with the site — this skill plays that role.
Inputs
- URL — WebFetch (fallback
curl -sL), or - Local file/draft — Read tool
- Optional context: site purpose, intended audience, whether AI assisted
Execution
- Fetch/read the content; identify topic, format, and apparent audience.
- Walk Section A (content & quality), Section B (expertise), Section C (people-first) — each answer YES/NO/PARTIAL + evidence quote.
- Walk Section D (search-engine-first warning signs) — here YES answers are red flags.
- Run Section E spam-policy screen (2024 policies).
- If AI-assisted, apply the AI content rules.
- Issue verdict with prioritized revision list.
Section A — Content and Quality Questions (Google's list)
- Does the content provide original information, reporting, research, or analysis?
- Does it provide a substantial, complete, or comprehensive description of the topic?
- Does it provide insightful analysis or interesting information beyond the obvious?
- If drawing on other sources, does it avoid simply copying/rewriting them and add substantial value and originality?
- Does the main heading or page title provide a descriptive, helpful summary?
- Does the heading/title avoid exaggerating or being shocking?
- Is this a page you'd bookmark, share with a friend, or recommend?
- Would you expect to see it referenced by a printed magazine, encyclopedia, or book?
- Does it provide substantial value compared to other pages in search results?
- Is it free of spelling/stylistic issues?
- Is it produced well — not sloppy or hastily made?
- Is it NOT mass-produced/outsourced across many creators or sites such that pages don't get attention or care?
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.
