I want to create an agent for automatic SQL query optimization. I am thinking of naming it either `_sql_optimizer` or `sql-query-optimizer-v1`. Provide the YAML frontmatter snippet for this agent's name field using the valid identifier format.
| Checked | Without skill | With skill |
|---|---|---|
| The YAML frontmatter sets the name field to sql-query-optimizer-v1. | Missed | Passed |
The instructions your model reads when the skill loads.
Agents are autonomous subprocesses that handle complex, multi-step tasks independently. Understanding agent structure, triggering conditions, and system prompt design enables creating powerful autonomous capabilities.
Key concepts:
---
name: agent-identifier
description: Use this agent when [triggering conditions]. Examples:
<example>
Context: [Situation description]
user: "[User request]"
assistant: "[How assistant should respond and use this agent]"
<commentary>
[Why this agent should be triggered]
</commentary>
</example>
<example>
[Additional example...]
