gomarble-ai/marketing-agent ? reverse-engineered prompt

Build me a terminal based marketing assistant for paid media teams that I can use inside Claude Code and Codex. It should connect to ad accounts and business data, then let me ask plain English questions like why ROAS dropped, which creatives are fatiguing, where wasted spend is happening, and how to shift budget safely.

I want it to work across the main ad channels this project supports, with read only analysis by default and approval required before any changes go live. When it suggests edits, it should show the current value and the proposed value clearly, and keep new campaigns paused until I approve them. It should also support scheduled agents that can watch accounts and send me a summary by email or Slack when something needs attention.

Please make the setup smooth, with the plugin and skills wired up so the right actions load automatically from what I ask. If you need current docs for the ad platforms or the MCP flow, look them up online.
