+# Initialize .gitignore for Claude Code
+
+Set up or update the project's .gitignore file with Claude Code specific patterns.
+
+## Core Claude Code Files to Ignore
+
+Ensure these Claude Code local configuration files are ignored:
+- `CLAUDE.local.md` - Local AI assistant instructions (root)
+- `.claude/settings.local.json` - Personal Claude Code settings
+- `.mcp.local.json` - Local MCP server configuration (root)
+
+## Development Patterns
+
+These common development artifacts will also be added:
+- `temp/` - Temporary working directory
+- `temp-*/` - Temporary directories with prefix
+- `test-*/` - Test directories with prefix
+- `debug-*.js` - Debug scripts
+- `test-*.js` - Test scripts
+- `*-test.js` - Test files with suffix
+- `*-debug.js` - Debug files with suffix
+
+## Current .gitignore Status
+
+!`[ -f .gitignore ] && echo "EXISTS: .gitignore found" && echo "---CONTENTS---" && cat .gitignore || echo "MISSING: No .gitignore file found"`
+
+## Task
+
+Based on the above status:
+1. Create `.gitignore` if it doesn't exist
+2. Add all patterns that aren't already present
+3. Preserve existing entries and comments
+4. Report what was added
+
+## Patterns to Add
+
+```gitignore
+# Claude Code local files
+CLAUDE.local.md
+.claude/settings.local.json
+.mcp.local.json
+
+# Temporary and debug files
+temp/
+temp-*/
+test-*/
+debug-*.js
+test-*.js
+*-test.js
+*-debug.js
+```
+
+Implement this by:
+1. Using the gitignore status above to determine what's missing
+2. Adding missing patterns with appropriate comments
+3. Preserving the existing file structure and entries
