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 | $0.00383 | $0.00383 |
| Opus 5.5 | $0.00153 | $0.00153 |
| Sonnet 5.5 | $0.00077 | $0.00077 |
| Haiku 4.5 | $0.00038 | $0.00038 |
Grade A, and why
quantflow-observable-instructions 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.
What it actually says
Observable Framework Instructions
These instructions apply to markdown files in frontend/src/, which are rendered by Observable Framework.
Math
Observable Framework uses KaTeX for math rendering. The syntax is different from standard markdown math (no $...$ or $$...$$).
-
Display math (block, centered): use a
texfenced code block:```tex E = mc^2 ``` -
Inline math: use the
textagged template literal inside an inline expression:The smoothing factor ${tex`\alpha`} controls decay. -
Do not use
$...$or$$...$$for math in Observable Framework pages. -
Do not use
\begin{equation}...\end{equation}(that convention applies only to mkdocs pages indocs/).
Downloads
Always render download actions as a <button> element (not an <a> link). Use the pattern:
const downloadData = () => {
const blob = new Blob([JSON.stringify(data, null, 2)], {type: "application/json"});
const url = URL.createObjectURL(blob);
const a = document.createElement("a");
a.href = url;
a.download = "filename.json";
a.click();
URL.revokeObjectURL(url);
};
display(html`<button onclick=${downloadData} style="cursor: pointer; background: var(--qf-primary); color: #fff; border: none; padding: 0.5em 1em; border-radius: 4px;">Download (JSON)</button>`);
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.
