Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00085 | $0.01552 |
| Opus 5.5 | $0.00034 | $0.00621 |
| Sonnet 5.5 | $0.00017 | $0.00310 |
| Haiku 4.5 | $0.00009 | $0.00155 |
Grade A, and why
developing-with-holoviz 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 16d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Developing with HoloViz
This is a routing skill. You MUST read every sub-skill file listed in the table below that matches the task BEFORE writing any code or giving any answer. Do not skip this step!
Contents
Instructions
- Identify which sub-skill(s) apply from the Loading Table below.
- Read each matching sub-skill file in full.
- Only after reading the sub-skill file(s), proceed with the task.
For new apps, prefer panel-material-ui over standard Panel templates — it provides modern Material Design components out of the box.

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.
