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 | $0.00159 | $0.08722 |
| Opus 5.5 | $0.00064 | $0.03489 |
| Sonnet 5.5 | $0.00032 | $0.01744 |
| Haiku 4.5 | $0.00016 | $0.00872 |
Grade A, and why
backlink 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 10d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
`page-read.mjs` reads only; it never fills or submits. `curl | grep` returns an How it starts
The opening of the file, as written. The whole thing — 609 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Two former Skills were merged in on 2026-08-16 and deleted: backlink-analyzer
(analysis templates, toxicity rubric, outreach — now in three references under
its original Apache-2.0 licence) and browser-harvest (pulling tables out of
logged-in dashboards — now ). The harvest
knowledge is general-purpose: ad platforms, e-commerce backends, any no-API
SaaS report. When a harvesting task has nothing to do with links, load this
Skill anyway and read that one reference.

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.
