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 5.1 | $0.00047 | $0.01217 |
| Opus 5.5 | $0.00019 | $0.00487 |
| Sonnet 5.5 | $0.00009 | $0.00243 |
| Haiku 4.5 | $0.00005 | $0.00122 |
Grade A, and why
Folio Artifacts 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 6d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Folio artifacts (kind: artifact)
An artifact is an interactive page: HTML + JS (+ files) that runs in a
sandboxed frame inside Folio. Use it when the user wants something a markdown
page cannot do: a dashboard, a calculator, a filter or a chart that reacts to
input, a small tool. A document never holds <script>/<iframe> — the
sanitizer removes them — so interactive content always goes into an artifact.
An artifact is in the tree, search, trash and Git like any page, but it is not
edited in place: you replace it whole.
Only in AGENT mode (publish_artifact is a write tool).
publish_artifact
| Input | Meaning |
|---|---|
space |
Space slug (required) |
id |
Replace this artifact (its page id). Omit to create a new one |
parentPath |
New artifact only: folder from the space root ("" = root), e.g. the folder of the current page |
title, icon |
Page title (default: the HTML <title>) and an emoji |
html |
The entry page: ONE complete, self-contained HTML document |
text + type |
Raw svg / markdown / mermaid text instead of html; Folio wraps it into a page |
files |
Extra files next to the entry (path, content, encoding: utf8 or base64), referenced from the HTML by relative path |
entry |
Entry file when it is not index.html |
sourceCode, sourceFileName |
The original JSX/TSX, kept verbatim next to the page (with type: react or canvas-tsx) |
type |
html (default), react, svg, markdown, mermaid, canvas-tsx |
origin, capabilities, properties |
Where it came from (other for something you built), what it needs from its host besides storage, page properties |
The url and embedCode inputs of the public MCP tool are not available in
the built-in chat: write the page yourself.
The reply has id, space, path, title, created, url and warnings.
Tell the user about the warnings. End the answer with the link
[<title>](/s/<space>/p/<id>).
Rules for the HTML
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.

Folio Artifacts is a skill published in the GitHub repository evergreen-it-dev/folio (80 stars, last pushed 5d ago), licensed MIT. It adds 47 tokens to every session and 1,217 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-22.
