What is pruefer-sprache?

A scientific-language review agent checks a chapter in German or English using fixed thresholds for sentence length, commas, nominalisations, repeated words, and prohibited patterns. It returns concrete wording corrections without changing the content or evidence.

Use it to edit the language of thesis chapters, find difficult sentence structures, and receive specific corrections for German or English academic writing.

It replaces a purely subjective language review with explicit checks and helps expose sentences that are too long, dense, or repetitive. It keeps the chapter's claims and sources unchanged.

Origin original 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	$0.00037	$0.00474
Opus 5.5	$0.00015	$0.00190
Sonnet 5.5	$0.00007	$0.00095
Haiku 4.5	$0.00004	$0.00047

Measured 26d ago against content hash 4e6058237a0b, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

pruefer-sprache 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 26d 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.

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.
