"content": "## Gate every generated ad before spend\n\nA minimal starting point: take one ad, score it with Spendict, and branch on the verdict so only creative that clears the bar ever reaches your ad platform.\n\n### How it works\n\n1. A manual trigger fires the run \u2014 swap it for your generator, a webhook, or a queue.\n2. A Set node holds the ad copy, platform, product context and audience. Replace it with the output of whatever writes your ads.\n3. Spendict's `assess_ad_creative` scores the ad across seven dimensions and returns a deterministic verdict plus the single predicted failure mode.\n4. A Switch branches on that verdict: `run` is ready to ship, `fix_first` should have its prioritized fixes applied and be re-assessed, and `kill` should be regenerated rather than spent on.\n\n### Setup\n\n- **Spendict** \u2014 free key at spendict.com/dashboard, then Header Auth `Authorization: Bearer spd_live_\u2026` on the Spendict node.\n- Wire your ad-platform or queue node to the `run` output. Leave the other outputs unconnected until you decide how to handle them.\n\n### Customization tips\n\nReplace the manual trigger and the Set node with your own generator to run this on autopilot."
