Create Local Plan

Create a detailed development plan stored locally in the .github/plans/ directory.

We are at planning stage so don't start to implement anything!

This time, the work requires greater accuracy. You are allowed to use more resources for reflection, so please ultrathink carefully before you begin.

Steps

Research: Conduct deep research on the project and the plan. Search for relevant information in the codebase, run commands like git log or git diff to understand the project history.
Plan Creation: Create a development plan in .github/plans/backlogs or .github/plans/bugs. Write the plan description in 正體中文, but use English for example code comments and CLI responses. The plan should be very detailed (try your best!) because I will assign these tasks to newbies in the future. Please write documentation that enables anyone to complete the work successfully. However, do not mention 'newbies' in the document, as I do not want to undermine the employee's confidence. Please write that enables anyone to complete the work successfully.
Prompt User: Show the plan details and ask if any changes are needed. If so, edit the plan description accordingly.
