When using /ultraplan (or the Ultraplan feature) from Claude Code CLI, a web session is launched on claude.ai to refine a plan. After the plan is refined and approved in the web session, the result does not teleport back to the originating CLI session as expected.

Description

When using /ultraplan (or the Ultraplan feature) from Claude Code CLI, a web session is launched on claude.ai to refine a plan. After the plan is refined and approved in the web session, the result does not teleport back to the originating CLI session as expected.

Steps to Reproduce

  1. In Claude Code CLI, enter plan mode and create a plan
  2. Run /ultraplan -- this opens a web session at claude.ai/code/session_*
  3. In the web session, refine and approve the plan
  4. Return to the CLI session -- the refined plan is not available

Expected Behavior

The refined plan from the web session should be sent back to the CLI session context, so the user can continue working with the merged/refined plan without manual copy-paste.

Actual Behavior

The CLI session has no access to the Ultraplan output. The user must manually copy-paste the plan back, which defeats the purpose of the seamless handoff.

Environment

  • Claude Code CLI (macOS, Darwin 25.4.0)
  • Shell: zsh
  • The web session URL was accessible and the plan was generated successfully on that end

Additional Context

The CLI displayed "Starting Claude Code on the web..." and provided a session URL. The web session ran fine and produced a plan. The disconnect is in the return path -- nothing comes back to the CLI.

extent analysis

TL;DR

The issue can be mitigated by investigating the communication mechanism between the Claude Code CLI and the web session to ensure seamless data transfer of the refined plan.

Guidance

  • Verify that the web session is correctly configured to send the refined plan back to the CLI session, potentially through an API or callback mechanism.
  • Check the Claude Code CLI documentation for any specific settings or flags required to enable the return of the refined plan from the web session.
  • Inspect the network traffic or logs during the web session to identify any potential issues with data transfer or errors that might prevent the plan from being sent back to the CLI.
  • Consider testing the Ultraplan feature with a different shell or environment to isolate if the issue is specific to zsh or macOS.

Example

No specific code snippet can be provided without more details on the internal workings of the Claude Code CLI or the web session. However, the solution likely involves ensuring proper API calls or callbacks are made to transfer the refined plan.

Notes

The exact solution depends on the internal implementation of the Claude Code CLI and its interaction with the web session. Without access to the source code or detailed documentation, the guidance provided is based on general principles of inter-process communication and data transfer.

Recommendation

Apply workaround: Given the lack of information on how to directly fix the issue, applying a workaround such as manually copying and pasting the refined plan or exploring alternative features of the Claude Code CLI that might offer similar functionality could be the most practical approach until a more integrated solution is found.
