If several coding agents edit the same repository at the same time, give each one its own Git worktree. A worktree is a separate working directory with its own checked-out branch, so one agent’s uncommitted edits cannot be overwritten by another agent working in a different directory. The repository’s history and object data remain shared. Worktrees do not isolate everything else an agent touches, such as dependencies, databases, ports, or credentials, so treat them as a fix for working-tree collisions only.
What a worktree separates, and what it leaves shared
A standard Git clone has one working directory and one checked-out branch at a time. Agents that all run in that directory compete for the same files on disk. One agent can rewrite a file while another is reading it, or save an edit that replaces a change the second agent just made.
A linked worktree gives each agent its own directory. Each directory has its own checkout and its own branch, while Git stores the object database once for the whole repository. That is the separation Andrew J. Pyle describes in his August 13, 2026 article, “A worktree per agent, so they never step on each other”: separate directories and separate branch state, sharing one object store.
The separation stops at the Git working tree. A worktree does not give an agent its own operating-system process space, CPU or memory allocation, package installation, database instance, network port, or set of credentials. If two agents start a development server on the same port, or write to the same test database, a separate worktree will not prevent that conflict.

When a worktree per agent is worth the setup
The deciding question is whether the tasks change overlapping files or shared working-tree state. Pyle’s guidance is conditional: give separate worktrees to concurrent writers whose edits could collide. Agents that only read code, or tasks that touch clearly different files, may not need the extra workspace.
| Situation | Separate worktree needed? | Reason |
|---|---|---|
| Two or more agents editing files in the same repository at once | Yes | Uncommitted edits in a shared directory can overwrite one another. |
| Agents editing unrelated files in different areas of the code | Optional | Collisions are less likely, but a shared checkout still means one agent’s build or test run can see another’s half-finished edits. |
| Read-only investigation, code review, or question answering | Usually no | Nothing is written to the working tree, so the extra directory adds setup without removing a risk. |
| Work that must start from an identical, reproducible code state | Yes, with an explicit baseline | A named branch or commit gives every agent the same starting point. See the baseline section below. |
Pyle reports running roughly thirty worktrees at once. That figure is his personal experience, published in 2026, and it is not a benchmark or a measured limit. No source found for this topic gives a maximum practical number of worktrees, so set the count by how much disk space, build time, and review capacity you have.
Create each worktree from a predictable baseline
An agent that starts from whatever branch or uncommitted state happens to exist locally can inherit changes nobody meant to include. Pyle’s approach is to name the starting point explicitly, typically origin/main, so each task begins from the same known commit.
-
From the main repository directory, fetch the latest remote state so
origin/mainis current:git fetch origin -
Create a worktree in a sibling directory, with a new branch that starts at the named baseline. The example below is from Pyle’s article:
git worktree add ../ajp-og-cards -b feat/per-page-og-cards origin/mainThe

If the task is to continue an existing branch, attach a worktree to that branch instead. Pyle’s article shows this pattern for one task per directory:
git worktree add ../work-feature-a feat/thing-agit worktree add ../work-feature-b feat/thing-b -
Point each agent at its own directory and confirm the state before it writes anything:
git -C ../ajp-og-cards statusThe output should show the expected branch and a clean tree. If it does not, stop that agent before it edits files.
These commands are the examples from Pyle’s article. They are not independently tested in this context, so confirm the branch names and paths in your own repository before running them.

- Branch already checked out elsewhere. Git does not normally let two worktrees check out the same branch. If
git worktree addrefuses, choose a new branch name with-b, or confirm which directory already holds that branch. - Path already exists. Choose a new directory name. Do not reuse a directory that contains another agent’s work.
- Baseline is stale. If an agent starts from an old
origin/main, rungit fetch originfirst and create the worktree again from the refreshed ref.
Integrate the branches afterward
Separate worktrees reduce interference while the work is in progress. They do not remove the need to reconcile the results. Two branches can change the same file, and the merge step is where that conflict appears.
-
Review what each worktree has changed against the baseline:
git worktree listThen, in each worktree, check
git statusandgit log --oneline origin/main..HEAD. -
Commit each agent’s work on its own branch, then push each branch for review.

Merge through your normal review process. Where two branches touch the same lines, resolve the conflict on purpose rather than accepting one agent’s version by default.
-
When a branch is merged and no longer needed, remove its worktree and clean up the directory:
git worktree remove ../ajp-og-cards
Pyle’s article describes this as ordinary Git review and merge practice. The worktree commands above are standard Git commands, not part of his example set.

- They do not eliminate merge conflicts. Overlapping changes still have to be resolved during integration.
- They do not isolate dependencies, environment variables, databases, ports, caches, or external services.
- They do not replace review. Each branch still needs the same checks as any other change.
Pyle’s summary puts the principle plainly: “When parallel work fights over shared state, don’t build a better referee. Remove the sharing.” That is editorial advice from the article, not a formal Git guarantee.

Evidence limits
The main source for this approach is Pyle’s August 13, 2026 article. It gives the separation model and the example commands, but it does not report controlled measurements of productivity, conflict rates, or practical worktree limits. Adjacent coding-agent documentation, including the MindFlock repository, the Pragma core-model documentation, and an OTICA workflow document, describes similar parallel-worker patterns. Those sources show the pattern appears in more than one tool; they do not establish that any of those tools is required, and they do not prove a performance benefit.
Git’s own documentation for git worktree is the authority for exact command behavior, including flags and removal rules. Check the version installed on your machine, since the behavior of individual subcommands has changed across Git releases.
