Use Cases:

= Everyday work: Organize files, analyze data, draft documents, and create slides with a conversational assistant that keeps the output visible.
= Coding: Explore repositories, fix bugs, build features, and run tests while reviewing diffs and tool calls side by side.
= Research: Find information, verify facts, and cite sources, turning raw queries into traceable, well-documented results.
= Background tasks: Run scripts, batch-process files, and schedule recurring reports so important work continues without constant attention.
= Plugin development: Build and install custom plugins—such as a floating Pomodoro timer—through agent-assisted coding in Creator mode.
