What it is

pr-lens is a TypeScript project under the MIT license, per the supplied metadata. Its description says it draws every pull request as animated architecture and data-flow walkthroughs, shown inside the pull request. Topics include architecture-diagrams, diagrams-as-code and mermaid-alternative.

Capabilities

The description and preview describe these ways to run it: - A GitHub App option that, per the preview, posts one comment per pull request and updates it on each push, without a model key from you. - A GitHub Action option that uses your own model key, saved as a repository secret. - Use as a skill for coding agents.

The preview frames it as an alternative to Mermaid, and that comparison is the project's own claim.
