Comment on the pages of a site you are reviewing and let your agent fix them. Review the pages your coding agent made, right where they are: on your dev server, on Laravel Herd, on staging. Select some text, right-click a spot, or drag a box over the page, and write what's wrong. Press ▷ and your comments go to your agent (Claude Code, Codex, opencode), which fixes them while the page updates in front of you. Each comment shows what the agent is doing and its reply. How it works • Run redpencil on your computer, pointing it at your site and its source folder: uvx redpencil --site https://my-site.test --source ~/code/my-site --wait • Click the redpencil icon once on that site. From then on its pages show the comment panel whenever a review is running. • Drag a box over the page to attach a screenshot of that area to your comment. Private by design • The panel appears only on the sites you turn on with the icon. • Comments and screenshots go only to redpencil on your own computer (127.0.0.1) and are saved as files in your project. Nothing is sent to us or anyone else. • Chrome asks for access to all sites because it allows screenshots only that way; the extension still does nothing on sites you haven't turned on.
