Problem Statement

I use Claude Projects on mobile to plan out projects — it's fast and convenient for ideation, outlining, and building context in a knowledge base. But once planning is done, there's no way to hand that context to Claude Code to actually build. I end up manually re-explaining the plan, re-uploading context, or copy-pasting between the two environments, which breaks the workflow and loses fidelity between planning and execution.

Proposed Solution

A handoff mechanism similar to what Claude Design now has with Claude Code (/design-sync) — where a Project's knowledge base, conversation history, and planning artifacts can be pulled directly into a Claude Code session. Ideally:

A command (e.g. /project-sync) run from Claude Code that imports a specified Project's context
The ability to trigger a handoff from the Project itself (mobile or desktop) that opens/primes a Code session
Optionally, changes made in Code (file structure, decisions made during build) sync back to the Project's knowledge base, so the plan stays current

Additional Context

Projects and Code currently serve two different stages of the same workflow — ideation and execution — but they're islands. Bridging them would let mobile-first planners pick up real implementation work without re-establishing context every time, the same way Design ↔ Code sync now closes that loop for visual work.
