Ghost

What it does

When your agent uses it

• Ghost server installation
• Site administration (installing
• Those belong to the official npm ghost-cli tooling

Example prompts

• “/ghost”

Requirements

• Python 3
• A credential in GHOST_ADMIN_KEY
• A credential in RECORD_KEY
• Compatibility (from SKILL.md): Requires GHOST_URL and GHOST_ADMIN_KEY env vars. Admin key in "id:secret" format from Ghost Admin → Integrations. Python 3.8+ and the `requests` library.

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1In Ghost Admin → Settings → Integrations, create (or open) a Custom Integration.
2. 2Copy its Admin API Key — one string, two colon-separated hex halves (id:secret). The separate Content API key from the same screen will…
3. 3At 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…
4. 4help and --dry-run work without credentials (lazy auth).

What it can do on your machine

Read from SKILL.md and the folder at commit c545c2b. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 2 files in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • jq

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • GHOST_ADMIN_KEY
  • RECORD_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Requires GHOST_URL and GHOST_ADMIN_KEY env vars. Admin key in "id:secret" format from Ghost Admin → Integrations. Python 3.8+ and the `requests` library.

  From compatibility in the SKILL.md frontmatter.

Context cost

Ghost loads about 2.4k tokens when it runs, and up to ~8.9k if it reads all its reference files. Until then it costs about 84 tokens; SKILL.md has 804 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~84

When it runs · the whole SKILL.md, loaded when a task matches

~2.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~8.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Manage Ghost CMS content over the Admin API — browse posts, pages, and tags, draft and publish content, schedule posts, and inspect site info from the terminal. Do not use this skill for Ghost server installation or site administration (installing, nginx, SSL, systemd, updates); those belong to the official npm ghost-cli tooling.

compatibility

Requires GHOST_URL and GHOST_ADMIN_KEY env vars. Admin key in "id:secret" format from Ghost Admin → Integrations. Python 3.8+ and the `requests` library.
