# TypeScript and Code Quality Check Hook
|
||||
#
|
||||
# This hook validates TypeScript files when they are created or modified.
|
||||
# It runs TypeScript type checking and Biome linting to ensure code quality.
|
||||
#
|
||||
# Installation:
|
||||
# 1. Copy to: .claude/hooks/on-tool-use/typescript-check.sh
|
||||
# 2. Make executable: chmod +x .claude/hooks/on-tool-use/typescript-check.sh
|
||||
# 3. Configure Claude Code to use this hook for Write/Edit operations
|
||||
#
|
||||
|

# Set up logging
