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 | $0.00067 | $0.00726 |
| Opus 5 | $0.00034 | $0.00363 |
| Sonnet 5 | $0.00013 | $0.00145 |
| Haiku 4.5 | $0.00007 | $0.00073 |
Grade A, and why
dns-connector 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 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.
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.
This is a copy
92% identical to dns-connector — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DNS-Shop Connector
Reads DNS-Shop inside the operator's Chrome over CDP. Qrator's JavaScript proof-of-work answers every dynamic page with HTTP 401 + a challenge script — no header trick clears it, but a real Chrome executes it natively. The connector renders the page and reads the DOM.
When to use
- Search DNS electronics catalog by text
- One product's price, old price, availability
Tools available
dns_search(query)— tiles from the rendered search pagedns_card(product_url)— one card. The URL carries/product/<id>/, where the id is a 16-hex string:/product/b7a1667f9b19ed20/. A bare id also works.dns_selfcheck()— tri-state canary
A green selfcheck does NOT mean the data is right
This connector is why that sentence appears throughout this repo. In July 2026
the product-id regex was fixed, search began returning 24 links, and
dns_selfcheck went green — while every item still came back with
title: null and price: null. The transport was fine; the parser understood
nothing.
dns_selfcheck answers one question: did the page load and did the extractor
return a shape. If a number has to be trusted, open the product page in the same
Chrome and read it.
The price on a DNS tile is not the smallest number on it
Three traps, all confirmed against the live grid on 2026-07-28:
- An instalment sits next to the price. A tile showing
58 999 ₽also showsот 5 751 ₽/ мес.. Anything that takes the minimum reports the monthly payment — a number that validates, looks plausible and is wrong. The extractor reads the named price node and skips instalment and bonus nodes. - The strikethrough price carries no currency glyph —
.product-buy__prevrenders a bare54 999, so a filter keyed on₽never sees it. - The first product anchor in a tile is the image link, which has no text.
Tiles are selected by the exact BEM block
.catalog-product, never by walking up from an anchor.
price_rub is None when no price could be read — never 0, never a guess. If
a whole page comes back unpriced the response carries a no_prices_on_page
warning: that is drift to investigate, not "free".
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.
