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 | $0.00035 | $0.01294 |
| Opus 5.5 | $0.00014 | $0.00518 |
| Sonnet 5.5 | $0.00007 | $0.00259 |
| Haiku 4.5 | $0.00003 | $0.00129 |
Grade A, and why
ghost-app-ui-dev-setup 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.
1. Check `curl -s -o /dev/null -w '%{http_code}' http://localhost:2368/ghost/` How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Set up a folder for Ghost app UI development
This prepares the current folder so a fresh chat can build a Ghost app the way
an outside developer would: Shade's skills installed, Shade's docs served by the
local Storybook, the app SDK packed from the Ghost checkout, and an AGENTS.md
that reads like an ordinary app project's.
The build chat must see only what an outside developer sees. Keep the checkout path out of every file in the folder, except the deny rules in step 8.
Do the steps in order. Each ends on a check; when one fails, stop and tell the
user. Commands and file contents are in reference.md.
1. Check the folder
- Confirm the current folder is empty. Hidden system files such as
.DS_Store, or an empty.claude/, are fine. Anything else: stop and ask. - Ask where the Ghost checkout is, suggesting
~/Code/Ghost. It's<checkout>below. - Check
<checkout>/apps/shade/package.jsonexists and the folder isn't inside<checkout>.
2. Ghost
- Check
curl -s -o /dev/null -w '%{http_code}' http://localhost:2368/ghost/prints200. - If not, offer to run
pnpm dev:upin<checkout>, which runs Ghost in the background and prints its URL. Run it only on a yes, then check again. - Remind the user that Settings → Labs → Private features → Apps must be on. You can't check it without logging in.
3. Storybook
Storybook serves Shade's docs as Markdown, which the skills read.
- Check
curl -sf -o /dev/null http://localhost:6006/llms.txtsucceeds. If so, go to step 4. - Otherwise start it detached, as in
Start Storybook, and poll
llms.txtevery few seconds for up to three minutes. If it never answers, show the end of its log and stop. - Once it answers, record its process as in Start Storybook. Tell the user it keeps running after this chat, and how to stop it. Only give the stop command for a Storybook this setup started.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ghost-app-ui-dev-setup is a skill published in the GitHub repository TryGhost/Ghost (55,632 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 1,294 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-30.
