[Opportunity] Kimi CLI — Plan Mode Implementation

[howardpen9]

Target Project

Kimi CLI (MoonshotAI/kimi-cli)

• Kimi #1354 — "I want a plan mode"

What

Implement a plan mode where users can:

1. Ask the agent to create a step-by-step plan before executing
2. Review and edit the plan
3. Approve execution step by step or all at once
4. Track progress through the plan

Why

• Explicit user request in Kimi #1354
• Claude Code and OpenCode both have mature plan mode implementations
• Plan mode is the [Cross-Ref] Windows Path Handling — Universal Pain Point Across All CLIs #1 differentiator for complex tasks — without it, agents take random walks
• High-visibility feature that would attract power users

Prior Art

Claude Code

• Toggle with Shift+Tab or /plan command
• Creates numbered step list
• User can edit steps before execution
• Integrated with permission system

OpenCode

• Similar plan/execute flow
• Subagent session forking for plan exploration

Implementation Plan

1. Add plan mode state to agent session (planning vs executing)
2. Create plan data structure (steps, status, dependencies)
3. Add /plan command or Ctrl-P toggle
4. Render plan in TUI with step status indicators
5. Allow step editing before execution
6. Execute steps sequentially with approval gates
7. Resume from failed step

Estimated Effort

Large (2-3 weeks)

Status
