description: Create an intelligent implementation plan with prompt enhancement. Use when planning a feature, designing architecture, starting a new task, or creating a detailed phased implementation roadmap.

# Plan — Intelligent Plan Creation

Creates enhanced implementation plans with prompt improvement before planning.

## When to Use

- Starting a new feature or task that needs structured planning
- Designing system architecture with phased implementation
- Creating a roadmap before delegating to implementation agents

## Don't Use When

- Task is trivial and needs no plan (just implement directly)
- An active plan already exists and implementation is underway

## Pre-Creation Check

Check the `## Plan Context` section injected by session hooks:
- **Active plan path shown** → ask user: "Active plan found: {path}. Continue with this? [Y/n]"
- **Suggested path shown** → ask user if they want to activate it or create new
- **"Plan: none"** → proceed to create new plan using naming pattern from `## Naming` section

## Workflow

1. Analyze the task — ask clarifying questions if requirements are unclear
2. Decide complexity: simple task → `ck-plan-fast`; complex task → `ck-plan-hard`
3. Enhance the prompt — expand the task description with full context and details
4. Execute the appropriate planning skill with the enhanced prompt
5. Activate the `planning` skill to structure the plan output

## Planning Modes

| Mode | When to Use |
|------|-------------|
| `ck-plan-fast` | Clear requirements, straightforward implementation, no research needed |
| `ck-plan-hard` | Complex architecture, unclear requirements, needs research |
| `ck-plan-parallel` | Large feature benefiting from parallel execution phases |

## Important Rules

- Do NOT start implementing — planning only
- Sacrifice grammar for concision in plan output
- List unresolved questions at the end of the plan
- Ensure token efficiency while maintaining quality
