name: fix-unused-imports description: Automatically detect and fix TypeScript unused imports/variables errors (TS6133). Use when encountering "declared but its value is never read" errors during tsc, build, or CI checks.

Fix Unused Imports

Automatically detect and remove unused imports/variables in TypeScript/JavaScript projects.

When to Use

This skill should be invoked when:

• tsc --noEmit fails with TS6133 errors
• Build or CI fails due to unused import/variable errors
• User asks to fix unused imports or clean up imports

Execution Steps

1. Identify the error: Parse the TypeScript error message to extract:

   • File path
   • Line number
   • The unused identifier name

2. Read the file: Use the Read tool to examine the file content around the error line.

3. Determine the fix strategy:

   • Single import: If the line is import { Foo } from 'module'; and Foo is unused, delete the entire line.
   • Multiple imports: If the line is import { Foo, Bar, Baz } from 'module'; and only Bar is unused, remove just Bar from the import list.
   • Unused variable: If it's a variable declaration, consider if it should be removed or prefixed with _.

4. Apply the fix: Use the Edit tool to remove or modify the unused import/variable.

5. Verify: Re-run tsc --noEmit or the original command to confirm the fix.

Example Error Patterns

Copysrc/pages/Example.tsx(24,3): error TS6133: 'ChevronRight' is declared but its value is never read.

Parse this as:

• File: src/pages/Example.tsx
• Line: 24
• Identifier: ChevronRight

Fix Patterns

Single Unused Import (delete entire line)

Copy// Before
import { UnusedComponent } from './components';

// After
// (line deleted)

One of Multiple Imports (remove from list)

Copy// Before
import { Used, Unused, AlsoUsed } from './components';

// After
import { Used, AlsoUsed } from './components';

Type-only Import

Copy// Before
import { type UnusedType, UsedType } from './types';

// After
import { UsedType } from './types';

Batch Processing

When multiple TS6133 errors exist:

1. Collect all errors from the TypeScript output
2. Group by file to minimize file reads
3. Fix all issues in each file before moving to the next
4. Re-verify after all fixes

Commands to Detect Issues

Copy# For prd-admin
cd prd-admin && pnpm tsc --noEmit

# For prd-desktop
cd prd-desktop && pnpm tsc --noEmit

# Full CI check
./quick.sh ci
