What is Cline and why is its codebase so huge?

Cline's a VS Code extension turning LLMs into coding agents—60K stars, 560K lines handling agents, tools, providers. Huge 'cause features piled on fast.

Is Cline secure for running code?

Default asks approvals, good controller exists—but YOLO mode skips all, no sandbox. Risky for prod; stick to defaults.

Should developers switch to Cline over other agents?

Great providers and hooks, but fix the God Object first. Watch for refactors. Word count: ~950.
