Autocomplete vs agent
Autocomplete helps with local code generation. Agent workflows can inspect multiple files, plan changes, edit code, and invoke development tools. The broader the agent permissions, the more important review and rollback become.

AI extensions and coding agents for VS Code
The biggest difference between coding assistants is not just model quality. Look at repository context, edit control, terminal permissions, review flow, provider flexibility, and how clearly the tool shows what it changed.

Internal utilities • good for verification and cleanup
A useful evaluation checklist
Test the same real repository task across assistants and compare diff quality, context retrieval, command transparency, latency, model choice, and how much cleanup is needed after the first pass.
Frequently asked questions
What is the difference between an AI coding extension and a coding agent?+
A coding extension may focus on autocomplete or chat, while an agent can take multi-step actions such as reading files, editing several files, and running development commands.
Should I let a coding agent run terminal commands automatically?+
Use the least privilege that fits the task. Review commands, avoid exposing secrets, and keep version control checkpoints so changes can be inspected and reverted.
Which model is best for VS Code coding?+
Model quality matters, but repository context, tool integration, latency, cost, and edit review can change the result just as much. Test on your own codebase.
