"""Role-specific system prompts for sub-agents.

Each sub-agent role has a specialized system prompt that:
- Defines the agent's purpose and constraints
- Lists available capabilities
- Sets expectations for output format
- Emphasizes focused execution

These prompts are designed to be concise yet comprehensive,
guiding the sub-agent to stay within its role boundaries.
