- [Test CalmLens webhooks on localhost](https://calmlens.com/blog/test-calmlens-webhooks-on-localhost): Forward your project's events to a local handler with the CalmLens CLI, verify their signatures, and see how test sends and delivery retries behave.
- [Moderating uploads and prompts in PolySnap](https://calmlens.com/blog/polysnap-calmlens-integration): A worked example of CalmLens in an image-generation app: private uploads, prompt checks before tokens are spent, cached decisions and signed webhooks.
- [Moderation rules that act on what was found](https://calmlens.com/blog/moderation-rules-that-act-on-what-was-found): CalmLens policies can act on qualifiers such as graphic, historical or support and prevention, and one account policy can run several projects.
- [Name your image sizes once with lenses](https://calmlens.com/blog/reusable-image-transforms-with-lenses): How CalmLens lenses turn resize and format rules into short, versioned CDN URLs, and how to define them from your deploy script.
- [Sending large files to CalmLens one part at a time](https://calmlens.com/blog/sending-large-files-one-part-at-a-time): Multipart uploads send a large file to CalmLens in ordered parts: how an upload opens, continues and ends, which limits apply and when moderation starts.
- [Following an asset from upload to webhook](https://calmlens.com/blog/following-an-asset-from-upload-to-webhook): Asset pages now show an asset's events and the webhook deliveries they produced, and the asset list can filter for flagged content and sub-assets.
