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 | $0.00056 | $0.03282 |
| Opus 5 | $0.00028 | $0.01641 |
| Sonnet 5 | $0.00011 | $0.00656 |
| Haiku 4.5 | $0.00006 | $0.00328 |
Grade A, and why
ddb-search 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 10d 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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Deutsches Zeitungsportal (DDB)
The national newspaper portal of Germany. It collects the holdings of the Staatsbibliothek zu Berlin, the state and university libraries, and dozens of regional institutions. It holds approximately 33.8 million digitised pages, and approximately 27.9 million of them are from 1850 to 1949. Use it for the German press. The 1920s and the 1930s, the years of the great Weimar mind readers, are the decades with the best coverage in the full collection.
The results are individual pages, not issues and not titles. A result tells you the newspaper, the date and the page number, and it includes the matched text.
Commands
ddb search "<query>" [--pages N|N-M|all] [--rows N] [filters] [--json]
ddb facets <field> ["<query>"] [--limit N] [filters] # what values a filter can take
ddb snippets <id> "<query>" # where a query appears inside one page or issue
ddb get <id> # download OCR text, prints path to the cached file
The filters for search and facets are --from-year, --to-year, --title TEXT (the newspaper title), --place TEXT, --language CODE (ISO 639-2, ger), --provider TEXT (the institution that holds the item) and --zdb-id ID.
There is no --sort option. The results come back in order of relevance. See the risks below.
facets — how to find a value, and how to describe a result set
ddb facets place|provider|language|title lists the values that a filter can take, with page counts, and it puts the largest counts first. It does two different tasks.
How to find the correct value. --place and --provider match a full string, and a near-miss is not a near-miss. It is silence. --place Halle reports 0 pages matched with no error. --place "Halle (Saale)" matches 1.1 million pages. --provider Bayerische matches nothing. --provider "Bayerische Staatsbibliothek" matches 8.3 million. You cannot guess which form the index holds, so look before you filter. --title is the one exception: it is analysed text with German stemming, so a fragment of a title operates correctly.
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.

ddb-search is a skill published in the GitHub repository nestordemeure/ddb-mcp (0 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 56 tokens to every session and 3,282 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
