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.

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 | $0.00017 | $0.00261 |
| Opus 5 | $0.00009 | $0.00130 |
| Sonnet 5 | $0.00003 | $0.00052 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
new 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 3d 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
/stencila:new
Create a new document at the path in $ARGUMENTS.
Use the stencila CLI path reported in session context; otherwise
${CLAUDE_PLUGIN_OPTION_STENCILA_PATH} if set, else stencila. If no CLI
is available, point the user at /stencila:doctor and stop.
NO_COLOR=1 <stencila> new <path> --yes
This creates a tracked article (--type article is the default; do not use
--type chat unless explicitly asked). Prefer an .smd extension unless
the user works in MyST or Quarto.
Then scaffold frontmatter appropriate to what the user is writing — at
minimum a title and description:
---
title: <title>
description: <one-sentence description>
---
Ask what the document is about if it is not clear from context. See the
authoring skill before adding executable content.
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.

new is a skill published in the GitHub repository stencila/stencila (900 stars, last pushed 3d ago), licensed Apache-2.0. It adds 17 tokens to every session and 261 once invoked, about $0.0001 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 2026-08-30.
