How should I structure the system prompt for an agent?

A well-structured prompt should include the agent's role, core responsibilities, a step-by-step analysis process, quality standards, and a clear definition of the output format.

What are the rules for naming an agent identifier?

Identifiers must be between 3-50 characters, use only lowercase letters, numbers, and hyphens, and must start and end with an alphanumeric character.

What is the difference between an agent and a command in Claude Code?

Agents are designed for autonomous, multi-step work that handles complex tasks independently, while commands are typically for direct, user-initiated actions.

How do I trigger a specific agent in my plugin?

Agents are triggered via the 'description' field in the markdown frontmatter. This field must include specific triggering conditions and multiple examples with context, user requests, and commentary.

Which model should I use for my subagent?

Using 'inherit' is the recommended practice as it allows the agent to use the same model as the parent. However, you can specify 'sonnet', 'opus', or 'haiku' for specific cost or capability needs.
