Ghost is a publishing platform for creating websites, blogs, memberships, subscriptions, and newsletters. Publishers and developers can use it through managed hosting or run it themselves, while contributors work on its monorepo, themes, and API.
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 | $0.00045 | $0.00982 |
| Opus 5.5 | $0.00018 | $0.00393 |
| Sonnet 5.5 | $0.00009 | $0.00196 |
| Haiku 4.5 | $0.00005 | $0.00098 |
Grade A, and why
build-ghost-app-ui scanned grade A with 1 finding 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 today.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build a Ghost app's UI
A Ghost app's screens use Shade (@tryghost/shade), the design system Ghost
Admin is built with. This skill sets Shade up and routes to the Shade skills
installed beside it; the rules live in Shade's docs. The app's manifest,
connect() and install belong to the build-ghost-app skill.
The docs
Docs links use https://shade.ghost.org. If the project's AGENTS.md says
where Shade's docs are (another address, or a source folder), use that
instead. At an address, start from <address>/llms.txt and fetch web pages
with curl -s <address>/docs/<page>.md, so the text arrives exact: a web
fetch tool summarises it and refuses localhost.
When sources disagree, trust them in this order:
- The installed
@tryghost/shadepackage (its code and type definitions; it ships no docs) decides what exists: components, props and imports. Its types match the install. - The docs at the address above decide how to use it.
- Ghost's source, if it's on disk, is reference only. Never import from it, and skip its Admin-only rules.
Set up
Check each step against the app, and do the ones it's missing:
- Install
@tryghost/shade@alphaand its peers from npm;latestis older.npm create vitescaffolds React 19, which npm refuses beside Shade, so move the React packages and types first, as Install shows. - Set up Tailwind and the stylesheet.
- Load the Fonts.
- Wrap the app in ShadeApp.
- Follow Admin's Light and dark theme.
- Set the Page frame and margins.
- If the app keeps state in the query string, follow App state in the URL.
- Add this section to the app's
AGENTS.md, creating the file if needed. Keep any line already there that says where Shade's docs are.
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.
