agent-disallowed-tools
<RuleHeader description="Agent disallowedTools must be an array of tool names" severity="error" :fixable="false" :configurable="false" category="Agents" />
Rule Details
This rule enforces that the `disallowedTools` field in agent markdown frontmatter is a valid array of strings. Each entry should be a tool name that the agent is prohibited from using. Validation is delegated to the AgentFrontmatterSchema Zod schema. Proper formatting prevents runtime errors when the agent framework parses tool restrictions.

disallowedTools as a single string instead of array

How To Fix
