AI Image Content Moderation

Check uploaded images against the app's content rules before anyone else sees them.

What it adds

An automated classification step on image upload that holds, flags, or clears content against per-category policy thresholds.

What your agent is told to do

5
  1. 1

    Find every path by which an image becomes visible to someone other than its uploader, including avatars, attachments, embeds, and public links, and put the check on all of them. A single unguarded upload path defeats the feature.

  2. 2

    Express policy as named categories with their own thresholds, each mapped to an action. A single unsafe score gives operators no way to be strict about one category and permissive about another.

  3. 3

    Hold anything above the review threshold in a state where the uploader can still see their own file but nobody else can, and reuse the moderation queue, action vocabulary, and appeal flow shared with AI Text Content Moderation rather than building a second one.

  4. 4

    Record every decision with the image reference, the categories and scores, the action taken, and who or what took it, and keep that record long enough to handle an appeal. Do not retain the image itself beyond the app's normal storage rules for the sake of the audit trail.

  5. 5

    Do not surface category names, scores, or thresholds to the uploader. Tell them the content was held for review and how to appeal; publishing the classifier's reasoning teaches people how to get around it.

Edge cases it handles

8
  • Per-category thresholds tuned to the app's actual policy are required. One generic score forces a choice between blocking harmless content and admitting content the policy forbids.
  • Scores in the uncertain band must go to a human queue rather than defaulting to allow or to block, and that queue needs a service-level expectation so held content does not sit for a week.
  • Content held for review must be genuinely inaccessible to everyone except the uploader and reviewers, including through direct storage links, cached copies, and thumbnails already generated.
  • False positives are certain. Give the uploader a stated appeal path, let a reviewer overturn a decision, and make the overturn restore visibility without requiring a re-upload.
  • Do not expose category names, confidence scores, or thresholds in responses, client code, or error messages, because each one is a hint for evading the check.
  • When the moderation provider is unavailable or times out, choose a documented failure posture — hold for review rather than publish — and make sure held items are re-checked automatically when service returns.
  • Rate limits and large batches need backoff and a queue on the app's existing background-job system, with the uploader told their image is pending rather than shown an error.
  • Re-uploading the same file must reach the same decision without a second classification, and a policy change must be able to trigger a re-check of previously cleared content.

Definition of done

9
  • Every path that publishes an image runs the check before the image is visible to others.
  • Policy is expressed as named categories with independently configurable thresholds and actions.
  • Held images are inaccessible to everyone but the uploader and reviewers, including through direct storage and thumbnail URLs.
  • Uncertain results reach a human review queue rather than defaulting to allow or block.
  • Uploaders have an appeal path and an overturned decision restores visibility without a re-upload.
  • Category names, scores, and thresholds are never returned to the uploader.
  • A provider outage holds content for review and re-checks it automatically when service returns.
  • The feature matches the existing design system.
  • No existing functionality is broken.

    It inspects, then implements

    Your agent reads your existing app first, then adds the feature to fit it.

Works with your stack

These instructions are written to adapt. They tell the agent to detect your framework, match your existing design system, and reuse what you already have — rather than assuming a particular stack.
