How it runs

The automated pipeline, trigger to output.

  • TriggerWebhook with generated image URLHTTP webhook
  • ActionSample dominant colors vs brand palette
  • LogicPass if within tolerance, else regenerate
  • ActionRe-render with tighter palette prompt via ReplicateReplicateReplicate
  • OutputUpload compliant image to R2CloudflareCloudflare R2
  • OutputEscalate to Slack if retries exhaustedSlack

What it does

Enforces brand color discipline on AI-generated art. After each render, it extracts the image's dominant colors and compares them against your approved palette within a tolerance. Off-brand images are rejected and regenerated with stricter prompting rather than silently published.

When to use it

Use it when generative models occasionally produce images that look good but clash with brand guidelines, and you need an automated gatekeeper. It is the quality layer that sits behind any of your hero-generation flows.

How it works

  1. 1A webhook trigger receives a newly generated image URL and the post title.
  2. 2The image's dominant colors are sampled and measured against the approved brand palette.
  3. 3A logic step checks whether the colors fall inside the allowed tolerance.
  4. 4If it fails, the prompt is rewritten with stronger palette constraints and Replicate re-renders, looping back to the color check up to a retry limit.
  5. 5Passing images are uploaded to R2.
  6. 6If retries are exhausted, the workflow posts to Slack to flag the post for manual design review.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HTTP webhookTrigger any URL on agent actions.
  2. 2
    Connect ReplicateImage, video, and model inference.
  3. 3
    Connect Cloudflare R2Object storage, S3-compatible.
  4. 4
    Connect SlackChannels, DMs, threads, mentions.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
