# Context Map

> Generate a context map of all files relevant to a task before implementing changes. Use when a user says "map the codebase for this change", "what files are affected", "show me dependencies", or before starting implementation to identify files to modify, dependencies, test files, and reference patterns.

# Context Map

## When to Use

Use this skill when:

- Preparing to implement changes and need to understand the affected codebase
- Identifying all files, dependencies, and tests related to a task
- Finding reference patterns and similar implementations in the codebase
- Creating a pre-implementation analysis to reduce missed changes

Before implementing any changes, analyze the codebase and create a context map.

## Task

{{task_description}}

## Instructions

1. Search the codebase for files related to this task
2. Identify direct dependencies (imports/exports)
3. Find related tests
4. Look for similar patterns in existing code

## Output Format

```markdown
## Context Map

### Files to Modify
| File | Purpose | Changes Needed |
|------|---------|----------------|
| path/to/file | description | what changes |

### Dependencies (may need updates)
| File | Relationship |
|------|--------------|
| path/to/dep | imports X from modified file |

### Test Files
| Test | Coverage |
|------|----------|
| path/to/test | tests affected functionality |

### Reference Patterns
| File | Pattern |
|------|---------|
| path/to/similar | example to follow |

### Risk Assessment
- [ ] Breaking changes to public API
- [ ] Database migrations needed
- [ ] Configuration changes required
```

Do not proceed with implementation until this map is reviewed.
