MCPUpdated October 8, 2026
Understanding the Hook Machine Workflow
The Hook Machine is a powerful tool that combines Hook Researcher, Hook Generator, Hook Grader, and Hook Reviser into one seamless workflow. It allows you to analyze a creator's top-performing videos, extract winning hook patterns, build a custom grading rubric, and generate/grade/rewrite hooks for any new topic. You can work across Instagram, TikTok, and YouTube Shorts.
Workflow:
- Sign up for an account on Sandcastles (must be Pro, Visionary or Titan plan)
- Connect Sandcastles to Claude and install the Sandcastles plugin:
- Add the Sandcastles connector in Claude by following How to set up the Sandcastles MCP in Claude.
- Add the plugin, which adds the Sandcastles slash commands, from the Claude directory at https://claude.ai/directory/sandcastles. If you uploaded the plugin zip file before, follow How to update the Sandcastles MCP plugin in Claude.
