Cline Desktop Adds Plugin System and Goal Plugin for Task Verification

Key Info

Cline Desktop now supports plugins written in TypeScript that extend the agent with slash commands, custom tools, lifecycle hooks (such as beforeTool and afterRun), and dynamic rules. A bundled Goal plugin uses a /goal command and an afterRun hook to keep Cline working until it verifies the task is complete.

Highlights

• Plugins are installed via Customize > Marketplace > Plugins, then used through slash commands like /goal
• The Goal plugin adds a /goal slash command plus an afterRun hook that nudges Cline to verify its work
• Cline can only finish the task by calling the plugin's custom mark_goal_complete tool once work is verified complete
• Plugin behavior is documented across Desktop, the CLI, and the SDK
• Cline Desktop is available for macOS, Windows, and Linux
