Ultraplan now supports an interactive refinement workflow where plans can be generated and refined in Claude Code on the web (claude.ai/code), then brought back to the local CLI for execution. Users see a "No, refine with Ultraplan on Claude Code on the web" option during plan approval, and approved plans are automatically applied locally.
Evidence
Enhanced ultraplan flow (search for "Ultraplan approved in browser", "Refine local plan", "No, refine with Ultraplan on Claude Code on the web")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
