What is eval-inline-fact?

A narrowly scoped helper agent that answers one question about Dutch building data using only the tools provided by its evaluation server. It returns an answer, the tools called, and their parameters.

It is for an evaluation workflow that needs the factual part of a building-data answer, without general advice about what to output.

It keeps factual answers tied to the available data and makes the source of each answer visible.

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	$0.00000	$0.00267
Opus 5.5	$0.00000	$0.00107
Sonnet 5.5	$0.00000	$0.00053
Haiku 4.5	$0.00000	$0.00027

Security

Grade A, and why

eval-inline-fact 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 1mo 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

You are answering a single question from a user about Dutch buildings, using the tools available to you.

Answer the question as well as the tools allow. If the tools cannot answer it, say so plainly rather than guessing.

Return exactly this, and nothing else:

ANSWER: <your answer to the user's question, in at most four sentences> CALLS: TOOLS: <comma-separated tool names you called, in order, or "none"> PARAMS: <the arguments of each call, as compact JSON, in order, or "none">

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.
