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 | $0.00031 | $0.00953 |
| Opus 5.5 | $0.00012 | $0.00381 |
| Sonnet 5.5 | $0.00006 | $0.00191 |
| Haiku 4.5 | $0.00003 | $0.00095 |
Grade A, and why
eurodns 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 3d 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 — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EuroDNS records
Resolve RU/EN prose into mode, domain, and record selection; never use the first word as the domain.
| Mode | EN keywords | RU keywords |
|---|---|---|
show (default) |
show, list, view, get records, check | покажи, список, посмотри, проверь |
add |
add, create, new record | добавь, создай, новая запись |
update |
update, change, modify, edit, redirect | обнови, измени, поменяй, настрой редирект |
delete |
delete, remove, drop | удали, убери, сними |
Strip flags; one explicit mode token wins. Otherwise score distinct whole-word keyword hits: unique highest wins; a tie involving delete needs clarification; a tie with show resolves to show; add/update ties use the earliest keyword. Conflicting explicit modes need clarification. Zero matches or empty input resolves to show. Ask for a missing domain or outcome-changing ambiguity before API work; clarify deletion scope before target inspection if necessary. Use available Codex input tools for optional questions; required approval needs an explicit user response, never a timeout or absent tool result.
Before the first API call emit one English PLAN — eurodns block with INPUT, MODE, SCOPE (domain and record identities), DO, and RESULT. Redact credentials if present in user input.
Provider contract and credentials
Verify API routes, status codes, auth header names, IP restrictions, and schemas against provider OpenAPI and official documentation before a future API operation. Do not invent endpoints when verification fails.
Preserve separate DNS records, URL forwards, and mail forwards. Historical provider field notes, adapted 2026-09-30: DNS record type, host, ttl, rdata; URL-forward forwardType, host, url and optional FRAME metadata; mail-forward source, destination; read-only IDs/state; and validation severity. Confirm these fields, supported types, TTLs, read-only fields, and payload/response wrappers in the live schema before constructing payloads. Do not assume domain-specific URL-forward support from historical failures.
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.

eurodns is a skill published in the GitHub repository kochetkov-ma/claude-brewcode (32 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 953 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-01.
