Add Admin API Endpoint

Quick Review

This skill provides clear, step-by-step instructions for adding Admin API endpoints to Ghost, covering file locations, controller setup, routing, and testing. The description adequately conveys what the skill does, and the instructions are specific enough for implementation. Structure is good with a clean overview and referenced details file. However, novelty is moderate - while this saves time understanding Ghost's architecture, adding API endpoints is a common backend task that a capable CLI agent could accomplish with repository exploration and documentation, though this skill does provide valuable Ghost-specific patterns and reduces discovery overhead.
