Optimize Imports

Automatically refactor imports across the codebase for better tree-shaking and smaller bundles.

What this skill does

1. •Convert wildcard imports to named imports
2. •Remove unused imports across all files
3. •Consolidate duplicate imports from the same module
4. •Separate type imports for better tree-shaking

How to use

Optimize all imports in the project:

/optimize-imports

Optimize a specific package:

/optimize-imports packages/fit

Optimize a single file:

/optimize-imports packages/fit/src/adapters/krd-to-fit.converter.ts

Transformations

1. Wildcard to Named Imports

Before:

import * as z from "zod";

const schema = z.object({ name: z.string() });

After:

import { object, string } from "zod";

const schema = object({ name: string() });

2. Separate Type Imports

Before:

import { KRD, toKRD, fromKRD } from "@kaiord/core";

After:

import type { KRD } from "@kaiord/core";
import { toKRD, fromKRD } from "@kaiord/core";

3. Remove Unused Imports

Before:

import { map, filter, reduce, sortBy } from "lodash-es";

const result = map(data, fn);

After:

import { map } from "lodash-es";

const result = map(data, fn);

4. Consolidate Duplicate Imports

Before:

import { fitToKRD } from "./converters";
// ... 50 lines later
import { krdToFit } from "./converters";

After:

import { fitToKRD, krdToFit } from "./converters";

Process

1. •Analyze: Use TypeScript LSP to find all imports and their usage
2. •Transform: Apply optimizations following project style guide
3. •Validate: Ensure no type errors after changes
4. •Report: Show statistics on optimizations made

Safety Checks

• •Always run pnpm lint after transformations
• •Run pnpm -r test to ensure no breaking changes
• •Create git commit with detailed changes if requested

Project-Specific Rules

Following CLAUDE.md conventions:

• •Use type keyword for type-only imports
• •Maintain kebab-case file names
• •Respect the 100-line file limit (may need to split files)
• •Preserve AAA test pattern structure
