Git worktrees let you give each independent AI coding task its own working directory and branch while keeping those checkouts connected to one repository. Create a worktree for each task, launch the agent in that directory, then review and integrate its changes yourself. Worktrees separate files and per-checkout Git state; they do not coordinate agents, prevent overlapping edits from conflicting, or act as a security boundary.
What a Git worktree isolates—and what it shares
A Git worktree is a working directory attached to a repository. The checkout made by git clone or git init is the main worktree; additional checkouts are linked worktrees. Unlike creating a separate clone for every task, linked worktrees share repository data while maintaining per-worktree state, including HEAD and the index. See the official Git worktree documentation.
That arrangement gives each agent its own directory and checkout without making the directories or changes magically compatible. Git does not schedule agents or decide how to divide work. If two tasks touch the same code, their changes can still conflict when you integrate them.
Set up one worktree per independent task
Choose tasks that can be developed and reviewed independently. Give each one a distinct branch and directory so you can tell which checkout belongs to which task.

- 【75% Space‑saving Layout】The KN85 series is a compact 85‑key keyboard (13.68" × 5.51" × 1.77") that keeps all the essentials (F1–F12, arrows, shortcuts) without the number pad. It frees up 25% of desk space for better mouse movement. Designed for small desks, laptop setups, gamers and minimalists. For frequent number‑pad input, choose our full‑size KN104 with a complete dedicated numpad, or opt for our new KN98 model — compact 99‑key that retains the numpad while saving desktop real‑estate
- 【Tri-Mode Connectivity for Multi-Device Workflow】Connect via USB‑C, 2.4GHz wireless, or Bluetooth 5.0 (3 channels supported), with ultra‑low latency (USB 2ms, 2.4G 5ms, BT 11ms). Switch seamlessly between Windows and Mac to work across your PC, laptop, tablet, smartphone, or gaming console. Perfect for programmer, student, creator, or hybrid worker. The built‑in 4000mAh rechargeable battery ensures stable wireless performance. Continue typing while charging via wired mode when power runs low
- 【Creamy Thocky Typing Sound】The gasket mount absorbs harsh vibrations and hollow echoes to produce a smooth marbly thock, rather than loud clacky taps. Each keypress feels softly cushioned. Whether you’re working late at home or typing in a shared office space, the mellow, ASMR-like tone makes every keystroke a genuinely enjoyable experience
- 【Hot-swap for Tailored Sound & Tactile】Pre-lubed Bsun linear switches (45-50gf actuation) deliver a buttery response. Compatible with both 3 pin and 5pin switches, they enables solder-free swapping. From beginners to frequent typists and dedicated writers, craft your preferred typing signature without complex modding
- 【RGB Backlighting & Programmable】A warm ambient glow surrounds PBT keycaps and case edges, creating a calm, inviting desk vibe for late-night workspace. Adjust hues and brightness through shortcut keys or companion software. The KN85 driver (Windows only, wired/2.4G mode) lets you remap keys and set custom macros to boost your daily productivity
- Start from the repository. In a terminal, change to the main worktree and check that the working tree is in the state you intend to use as the starting point.
- Create a worktree and a new branch. Run
git worktree add -b <branch-name> <path> <start-point>, replacing the placeholders with a unique branch, a directory path, and the commit or branch to start from. For example:git worktree add -b agent/docs ../project-docs HEAD. The-boption creates the branch;HEADstarts it from the current commit. Git documents the command and options in its worktree reference. - Repeat for other independent tasks. Use a different branch and path for each. A branch already checked out in another worktree is not the normal choice for a parallel checkout; plan distinct branches rather than forcing the same branch into multiple worktrees.
- Launch each agent in its assigned directory. Set the agent’s working directory to that worktree and give it a bounded task. If tasks might touch common files, make the ownership or coordination expectations explicit.
For example, if you have separate documentation and test tasks, create branches such as agent/docs and agent/tests in separate sibling directories, then start each agent from its corresponding path. These names and paths are examples, not special Git conventions.
Review and integrate each agent’s work
Before accepting a change, inspect the branch and diff in that worktree, run the project’s usual checks, and decide how to integrate the result. A separate checkout makes it easier to inspect one task without confusing its working files with another’s; it does not replace code review or integration planning.

- Confirm the worktree is on the branch you assigned.
- Inspect the diff and check for unintended or overlapping edits.
- Run the project’s relevant tests, builds, or other normal checks.
- Integrate the branch using your team’s usual Git workflow, resolving conflicts deliberately.
Inspect and clean up worktrees
Use git worktree list to see the worktrees Git knows about. When a linked worktree is finished and clean, remove it with git worktree remove <path>. Review the command documentation for behavior and options when a worktree has uncommitted changes or submodules; do not assume removal is appropriate until you have dealt with any work you need to keep.
If you deleted a linked worktree directory manually, its administrative record may remain. git worktree prune removes stale records. If you moved a linked worktree outside Git, git worktree repair can restore the connection in supported cases. Git also provides lock, unlock, and other worktree management operations; consult the official reference for their exact use.

Know the limits of the setup
- Separate directories are not a security boundary. A worktree by itself does not restrict an agent’s access to credentials, network resources, or other filesystem paths. Those protections depend on the agent runtime and operating environment.
- Shared repository data is not shared working files. Worktrees share underlying repository data, but each has its own checkout and per-worktree state.
- Parallel work still needs coordination. Distinct branches help separate tasks, but overlapping edits can require conflict resolution or redesign before changes can be combined.
Claude Code’s CLI reference documents command-line usage and flags, but it does not establish a native worktree feature or recommend this workflow; using a worktree as the agent’s working directory is a Git-based setup choice. See Anthropic’s Claude Code CLI reference.
