A new plugin for Claude Code, named claude-meseeks, injects a Mr. Meeseeks voice line whenever the AI is waiting for user input. The plugin plays different clips depending on Claude's state: a "done" clip when Claude has finished and is awaiting a prompt, and an "asking" clip when it requires approval. Autonomous tasks, like background agent activity or permission runs, remain silent.

The plugin is installed via the marketplace using the command: `/plugin marketplace add thephw/claude-meseeks/plugin install mr-meeseeks@claude-meseeks`. It requires an audio player on the system's PATH, with automatic detection of tools like `afplay` (macOS), `ffplay`, or `mpg123`.

The voice clips are sourced from Rick and Morty and are embedded within a Go program named `meeseeks`. Users can customize clips by replacing `.mp3` files in the `audio/` directory and rebuilding the binaries. The plugin's philosophy mirrors that of Mr. Meeseeks: existing for a single purpose and ceasing to exist once that task is complete, advocating for focused, single-objective Claude Code sessions.
