Cursor started as 'VS Code with better autocomplete' in 2023. By 2026 it's an IDE with a real agent baked in. The Composer and Agent modes let you say 'add dark mode across the whole app' or 'refactor this entire feature to use Server Components' and watch it happen across 20 files.
Section 1
Composer vs. Agent modes
Compare the options
| Mode | What it does | When |
|---|---|---|
| Tab completion | In-line AI suggestions as you type | Baseline coding |
| Chat | Q&A about code, focused on current file | Asking questions, small edits |
| Composer | Multi-file edits with your approval on each | Focused refactors |
| Agent | Autonomous multi-step task execution | 'Implement this whole feature' |
Agent-mode prompts that work well
Good Agent prompts:
• "Add auth to this app using Clerk. Follow the existing middleware pattern."
• "Refactor the feed component to use virtualized rendering. Maintain the existing test coverage."
• "Find and fix every task list in src/ that says 'fix later'."Understanding "Cursor Agent — autonomous coding in your editor" in practice: AI-assisted coding shifts work from syntax recall to design thinking — models handle boilerplate so you focus on architecture. Cursor Agent is the editor equivalent of Claude Code — give it a goal, it reads, writes, tests, and commits across files — and knowing how to apply this gives you a concrete advantage.
- Apply Cursor Agent in your ai-coding workflow to get better results
- Apply Composer in your ai-coding workflow to get better results
- Apply autonomous coding in your ai-coding workflow to get better results
- 1Use AI to generate unit tests for an existing function
- 2Ask AI to refactor a messy function and explain the changes
- 3Have AI suggest a code review for a recent pull request
