## Highlights

### GitHub Copilot CLI agent with scoped configuration

Added dedicated github-copilot-cli target that writes VS Code-compatible local config to `.vscode/mcp.json` and Copilot CLI global config to `~/.copilot/mcp-config.json`, preventing conflicts and enabling flexible integration. (Author: [@andrelandgraf](https://github.com/andrelandgraf/))

### Gitignore flag prevents accidental API key leaks

Implemented --gitignore flag to automatically add generated files to .gitignore with proper messaging about what the flag does and warnings when combined with global installs. (Author: [@mezotv](https://github.com/mezotv/))

### Fixed Codex integration header field mapping

Corrected MCP config generation for Codex to use http_headers instead of headers, verified against official Codex source code. (Author: [@RhysSullivan](https://github.com/RhysSullivan/))

### OpenCode config detection and MCP command structure

Fixed OpenCode integration by correcting config filename detection (opencode.json not .opencode.json) and adjusting MCP command generation to match OpenCode's expected format. (Author: [@IdrisGit](https://github.com/IdrisGit/))
