Multi-File Editing Task

Implement the following feature: {{featureDescription}}

**Affected files (likely):** {{expectedFiles}}

**Requirements:**
{{requirements}}

**Constraints:**
- Follow the existing code patterns in this project (check CLAUDE.md)
- Do not modify files outside the scope of this feature
- Maintain all existing tests — if you break one, fix it
- Add TypeScript types for any new interfaces or function signatures
- If you need to install a new dependency, ask me first before proceeding

**Implementation approach:**
1. Read the relevant files first and explain your plan
2. Wait for my approval before making changes
3. Implement changes file by file
4. After all changes, run {{testCommand}} and {{lintCommand}} to verify

Show me a brief plan before you start coding.
