This guide is for Cursor users moving toward agentic workflows — running Claude Code or other terminal agents on larger, longer-horizon tasks. Cursor is still a great IDE. This is about the layer of work that is better served by terminal agents and a dedicated manager for running them in parallel.
| cursor | pane | note |
|---|---|---|
| .cursorrules | CLAUDE.md | place at repo root; Claude Code reads it automatically on every session |
| Composer / Agent tab | a pane running Claude Code | each pane is a terminal running any CLI agent; worktree created automatically |
| tab model | worktree model | Cursor tabs share one workspace; Pane panes each get a separate git checkout — see note below |
| @-mentions for context | @filename + MCP servers | Claude Code supports @filename syntax; MCP servers extend context to external tools |
| auto-indexing | no equivalent | Claude Code reads files on demand; no background index |
| ⌘L (chat) | agent terminal in each pane | the agent terminal is the chat; no separate chat panel |
| ⌘I (Composer) | ⌘K (command palette) | Pane's ⌘K opens git actions, not an AI composer — the agent lives in the terminal |
The tab vs worktree mental model is the most important difference. Cursor's tabs let you view multiple files in one working directory. Pane's panes each have a separate git checkout of the repo. That isolation is what makes parallel agents safe — but it means you are not editing files "in Pane" the way you edit them in Cursor. Pane is for running agents; your editor stays your editor.
.cursorrules to CLAUDE.md at the repository root. The content is plain text in both cases — it transfers directly. Claude Code reads CLAUDE.md automatically on every session without a prompt reference.
