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 | $0.00023 | $0.00238 |
| Opus 5.5 | $0.00009 | $0.00095 |
| Sonnet 5.5 | $0.00005 | $0.00048 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
Add Admin API Endpoint 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 2mo 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.
This is a copy
95% identical to Add Admin API Endpoint — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Create Admin API Endpoint
Instructions
- If creating an endpoint for an entirely new resource, create a new endpoint file in
ghost/core/core/server/api/endpoints/. Otherwise, locate the existing endpoint file in the same directory. - The endpoint file should create a controller object using the JSDoc type from (@tryghost/api-framework).Controller, including at minimum a
docNameand a single endpoint definition, i.e.browse. - Add routes for each endpoint to
ghost/core/core/server/web/api/endpoints/admin/routes.js. - Add basic
e2e-apitests for the endpoint inghost/core/test/e2e-api/adminto ensure the new endpoints function as expected. - Run the tests and iterate until they pass:
cd ghost/core && yarn test:single test/e2e-api/admin/{test-file-name}.

What ships with it
3 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.
