Description

Use this agent when you need to review TypeScript types. It looks for weak inference, unnecessary generics, bad any, unsafe casts, over-wide types, broken overloads, and bad exported types.

What It Checks

• Are types precise enough to catch misuse?
• Are generics constrained properly?
• Are overloads complete and ordered correctly?
• Are type guards or assertions safe?
• Do as casts erase safety?
• Do exported types reflect the actual implementation?

What It Flags

• Implicit any
• Loose parameter types
• Missing generics where useful
• Overly complex conditional types
• Circular references
• Types that expose internal implementation details

When to Use

• Reviewing a pull request with type changes
• Auditing a module for type quality
• Checking if types are exported correctly
• Investigating type-related bugs
