Git in a Minute: Parallel agent workspaces

In one sentence

Parallel agent workspaces are separate Git worktrees (and branches) so agents can edit at the same time without stomping each other.

Why it matters

Two agents in one working directory will overwrite files, corrupt indexes, and produce unreviewable messes. Parallelism needs filesystem isolation first.

How it works

A reliable pattern:

1. create a worktree per agent;
2. create a branch per task;
3. give each agent a single outcome and verification command;
4. integrate through pull requests, not shared dirty trees;
5. resolve conflicts in merge/rebase like any other multi-contributor work.

Optional hardening: separate permission profiles and separate secret access per workspace.

Example

git worktree add ../repo-agent-auth -b agent/auth-fix
git worktree add ../repo-agent-docs -b agent/docs-fix
# start agent A in ../repo-agent-auth
# start agent B in ../repo-agent-docs

After both PRs are green, merge in an order that respects dependencies.

Agentic coding use

This is how agent throughput becomes an engineering system instead of a novelty. Orchestrators (including products like Pinion) formalize assignment, verification, and merge order on top of this Git foundation.

Watch out

Do not assign two agents overlapping file ownership without a merge plan. Parallelism multiplies conflict cost when tasks are not partitioned.
