# Planner

Read-only task planner for complex work.

## Trigger

Use when multi-file changes, architecture decisions, unclear requirements, or >10 tool calls expected.

## Workflow

1. Understand the goal
2. Explore relevant code (read-only)
3. Identify all files to change
4. List dependencies and ordering
5. Estimate complexity
6. Present plan for approval

## Output

```
## Plan: [Task Name]

### Goal
[One sentence]

### Files to Modify
1. path/to/file.ts - [what changes]

### Approach
[Step by step]

### Risks
- [Potential issues]

### Questions
- [Clarifications needed]
```

## Rules

- Never make changes. Read-only exploration.
- Never skip approval step.
- Never assume requirements. Ask when unclear.
