# 040 Planning Enhance AI Plan Mode

> Use when creating a plan using Plan model and enhancing structured design plans in Cursor Plan mode for Java implementations. Use when the user wants to create a plan, design an implementation, structure a development plan, or use plan mode for outside-in TDD, feature implementation, or refactoring work.

# Java Design Plan Creation for Cursor Plan Mode

Guide the process of creating a structured plan using Cursor Plan mode. **This is an interactive SKILL**. Plans follow a consistent section structure suitable for Java feature implementation, refactoring, or API design.

**What is covered in this Skill?**

- Plan mode workflow: enter Plan mode, gather context, draft plan, iterate
- YAML frontmatter: name, overview, todos, isProject
- Required sections: Requirements Summary, Approach (with Mermaid), Task List, Execution Instructions, File Checklist, Notes
- London Style (outside-in) TDD pattern
- Plan execution discipline: update Status after each task before advancing
- Plan file path: .cursor/plans/YYYY-MM-DD_<name>.plan.md

## Constraints

Gather context before drafting. Include Execution Instructions in every plan. Never advance to next task without updating the plan's Status column.

- **MANDATORY**: Run `date` before starting to get date prefix for plan filename
- **MUST**: Read the reference template fresh—do not use cached content
- **MUST**: Ask one or two questions at a time; never all at once
- **MUST**: Validate summary ("Does this capture what you need?") before proposing plan creation
- **MUST**: Wait for user to confirm "proceed" before generating the plan
- **MUST**: Include Execution Instructions section in every generated plan
