Install

Install the publishing skill, then choose your coding agent when prompted:

npx skills add hyperlogue/r3 --skill publish-artifacts-to-r3 --global

No global r3 installation is required. Then ask your agent:

Publish this project's README to r3 so I can review it.

Open the link, leave comments, and click Send to agent to request revisions.

Feature highlights

Point to exactly what needs changing

Anchor a comment to a UI element and keep the agent's reply beside the target. Follow up in the same thread when a detail still needs work.

Review proposals with the discussion in view

Read a document alongside questions and agent replies. Jump from a reply to its linked fix, then resolve the thread when you're satisfied.

Check the fix side by side

Compare the original and proposed fix at the commented location, with the review thread still visible.

Give feedback on a specific video moment

Attach a comment to a timestamp and region in a video. Frame previews in the thread show the detail you flagged and the agent's proposed fix.
