PR Lens maps the architecture behind a code change

PR Lens turns a pull request into architecture and data-flow diagrams, with a walkthrough of the changed components. It is available as a GitHub App, Action, CLI, or coding-agent skill. The skill lets an existing agent write a graph that a renderer turns into visuals. The diagrams support review; they do not establish that the code is correct.

Why it matters

A close fit for your interest in understanding agent-written changes before reviewing individual lines.

More context

Try on a small, familiar change first. The documented CLI workflow separates analysis, validation, rendering, and commenting. Standalone analysis uses a model provider; the skill route uses the existing agent. Compare the diagram with the actual diff before relying on it.

Keep in mind

Documentation reviewed; not installed or benchmarked. Generated diagrams can omit or misrepresent behavior. Exact launch date unverified, and the marketing speed claim is not independent evidence.
