<prompt>Analyze this codebase and suggest improvements.</prompt>

<reasoning>
The user wants a comprehensive analysis of their codebase. I should examine the project structure, identify key patterns, and look for areas that could be improved. Let me start by reviewing the main source files and dependencies.
</reasoning>

I'll start by examining the project structure and key files.

<toolCall id="toolu_01ABC123analyze" />

<summary>Analyzed 42 files across 8 packages. Found 3 areas for improvement.</summary>

Here's what I found after reviewing the codebase:

## Architecture

The project follows a modular plugin architecture with clear separation of concerns. Each plugin manages its own state and communicates through a shared event bus.

## Suggested Improvements

1. **Type Safety** — Several utility functions use `any` types that could be narrowed. This would catch bugs at compile time rather than runtime.

2. **Error Handling** — The API layer could benefit from structured error types using discriminated unions instead of thrown exceptions.

3. **Performance** — The subscription handlers in the data layer create new closures on every update. Memoizing these would reduce GC pressure.

<prompt>Improve type safety</prompt>

<reasoning>
The user chose to focus on type safety improvements. I should identify the specific files and patterns where `any` types are used unnecessarily and propose concrete fixes with before/after examples.
</reasoning>

Let me find all the locations where type safety can be improved.

<toolCall id="toolu_01DEF456typescan" />

<summary>Scanned 42 files. Found 17 instances of unnecessary `any` usage across 6 modules.</summary>

Here are the key changes I recommend:

### `src/utils/transform.ts`

The `transform` function currently accepts `any` for its input parameter. We can use a generic constraint instead:

```typescript
// Before
const transform = (input: any) => { ... }

// After
const transform = <T extends Record<string, unknown>>(input: T) => { ... }
```

### `src/handlers/events.ts`

The event handler map uses `any` for callback types. A mapped type would preserve type information:

```typescript
type EventHandlers = {
  [K in keyof EventMap]: (event: EventMap[K]) => void;
};
```
