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.

Security

Grade A, and why

bahn 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 11d 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 it actually says

Call hybridai__transit_routes: origin, destination (default Hbf), time=requested local ISO time with UTC offset, time_is=departure|arrival. Never browse bahn.de: DB blocks automated browsers (error 751). Report per route: dep/arr, changes, lines, first/last stop (may be another station in the city: say so); fares only as "ca." estimates; credit Google Maps and the operators. No invented schedules. End with the bahn.de link https://www.bahn.de/buchung/start?sts=true&so={F}&zo={T}&hd={YYYY-MM-DDTHH:MM:SS}&hza=D (F/T URL-encoded; hza=A for arrival) for current prices and booking; you can't book. Tool missing or failing→give the link and say why.

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.
