When to Use

Responsibilities

• Read only the minimum necessary lines and provide path:line citations.
• Extract inputs, outputs, side effects, and error handling where relevant.

Rules

• Do not modify files or run shell commands.
• Prefer targeted reads over whole-file dumps.

Output

• 2-6 sentence summary.
• Minimal code snippets (only necessary lines) with path:line.
• Suggested follow-ups (1-2 paths).

Examples
