A command-line tool for managing content in Ghost, a publishing system for websites and blogs, through its administrator API. It works with posts, pages, tags, drafts, scheduled content, published content, and site information.

Use it to browse, draft, publish, and schedule posts and pages, manage tags, inspect site details, and preview commands without credentials using help or dry-run modes.

It lets developers manage Ghost content from scripts or a terminal instead of relying on the web dashboard. It also uses the administrator credentials needed to see and change unpublished content.

ghost — Skill for Claude Code and Codex by magnus919

Install

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.

Any agent

npx skills add magnus919/agent-skills --skill ghost

Clone the repo

git clone --depth 1 https://github.com/magnus919/agent-skills

Made for: Claude Code, Codex.

Its marketplace also offers this one on its own, as the plugin ghost — /plugin install ghost after adding the marketplace above.

Token cost

What it costs to keep this loaded

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	$0.00070	$0.02232
Opus 5	$0.00035	$0.01116
Sonnet 5	$0.00014	$0.00446
Haiku 4.5	$0.00007	$0.00223

Measured 9d ago against content hash 5c1c6d1855ef, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

ghost 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/test_ghost.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ghost — Ghost CMS content from the terminal

Drive a Ghost CMS site's Admin API (v5/v6, Accept-Version: v6.0): list posts by status including drafts, create and publish pages and posts, manage tags, and check site info. Drafts, scheduled posts, and published content are all visible here because every call authenticates with a per-request Admin JWT built from your id:secret integration key.

Setup

export GHOST_URL="https://your-ghost-site.com"
export GHOST_ADMIN_KEY="<RECORD_KEY>"   # id:secret from Ghost Admin → Integrations

In Ghost Admin → Settings → Integrations, create (or open) a Custom Integration.
Copy its Admin API Key — one string, two colon-separated hex halves (id:secret). The separate Content API key from the same screen will NOT let you see drafts; see Known Gotchas.
At request time the CLI signs a short-lived JWT per call: HS256 signature keyed by the secret half after hex-decoding it to raw bytes, kid header carrying the id half, audience /admin/, exp five minutes after iat, sent as Authorization: Ghost <token>. You never handle the token yourself.
--help and --dry-run work without credentials (lazy auth).

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.
