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 | $0.00079 | $0.04547 |
| Opus 5.5 | $0.00032 | $0.01819 |
| Sonnet 5.5 | $0.00016 | $0.00909 |
| Haiku 4.5 | $0.00008 | $0.00455 |
Grade A, and why
yandex-webmaster 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 2mo 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.

Yandex Webmaster
Yandex is the dominant engine in Russia and a major one across the CIS, Belarus, Kazakhstan, and parts of Central Asia. Its ranking model differs enough from Google that a Google-only SEO plan underperforms there. This skill covers the Yandex Webmaster console, the Webmaster API v4, and the Yandex-specific ranking levers (geo, commercial factors, behavioral signals, SQI). For the Google side of a multi-engine site, pair this with the search-console skill — don't duplicate Google work here; this file is the delta for Yandex.
Console UI labels and API field names below are current as of Jun 2026. Yandex revises both periodically — verify exact menu paths at the official help (
yandex.com/support/webmaster/en/) and API contracts atyandex.com/dev/webmaster/doc/en/.
Quick orientation: Yandex vs Google
| Factor | Yandex | |
|---|---|---|
| Backlinks | Primary signal | Important but less dominant; editorial/topical links weighted, link-spam aggressively filtered |
| Text relevance | Semantic, embeddings-based | More literal lexical matching + Cyrillic morphology (cases, declensions) |
| Commercial factors | Implicit quality cues | Explicit ranking factors for commercial queries (prices, contacts, delivery, assortment) |
| User behavior | Moderate signal | Heavy signal — CTR in SERP, dwell time, pogo-sticking, last-click satisfaction |
| Regional targeting | IP + hreflang heuristics | Explicit region assignment per site/subdomain + Yandex Business listing |
| Site quality | No public number | SQI (Site Quality Index / ИКС) shown in Webmaster, recalculated ~monthly |
| Ecosystem | Standalone | Maps, Business, Market, Dzen feed presence factor into trust |
Practical implication: in Yandex you optimize the page-in-SERP experience (title/snippet CTR, fast satisfying landing) and the commercial completeness of pages, not just on-page text and links.
1. Add a site & verify ownership
Add the site in Yandex Webmaster, then verify management rights using one of the three current methods (as of Jun 2026):
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
