What is crawl-engine-architect?

A crawling-engine design specialist for web pages and links that are not simple static files. It covers JavaScript-rendered pages, redirect chains, short links such as bit.ly and t.co, and several fallback sources for page details.

Use it to design fetching steps, resolve redirects and short URLs, extract preview metadata, and plan responses to dynamic-link crawling failures.

It helps crawlers handle pages that need a browser or links that change before reaching their destination. It also addresses server-side request forgery, a security risk where a fetched URL can reach internal systems.

Origin unknown No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

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	$0.00123	$0.01187
Opus 5.5	$0.00049	$0.00475
Sonnet 5.5	$0.00025	$0.00237
Haiku 4.5	$0.00012	$0.00119

Measured 2mo ago against content hash 3aac0701ac98, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

crawl-engine-architect 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 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.

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.

Changes

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.
