+# Agent Development Rules
+
+## Required Frontmatter
+
+All agent files MUST include this frontmatter:
+
+```yaml
+---
+name: descriptive-name
+description: |
+  Multi-line description of when to use this agent.
+model: opus|sonnet|haiku
+color: blue|green|yellow|purple|cyan|magenta
+tools: ["Read", "Glob", "Write"]
+---
+```
+
+## Conventions
+
+- Agent names use kebab-case with `-agent` suffix
+- Description must explain WHEN the agent should be used
+- Model choice: opus for analysis, sonnet for implementation, haiku for scanning
+- Color must be unique within the plugin
