git-worktree-decisionv1.0.1

A developer is mid-way through a long-running feature branch with a dirty index, warm build cache, and an attached debugger. A P1 production bug arrives that must ship immediately without losing the current working state or committing half-finished code.

An engineering team launches multiple autonomous coding agents to work on separate tickets in the same repo. Without separate worktrees, agents overwrite each other's uncommitted edits and each agent's test suite observes the other's half-written files.

A platform team needs to diff the output of a legacy version against a refactored version at the same moment, or port a fix across two major release lines. Both working states must be live and runnable simultaneously to compare behavior.

A developer has reproduced a hard-to-catch bug and has a bisect or debugger session running that must not be disturbed. Meanwhile, routine feature work still needs to proceed on the same repository without invalidating the reproduction.

After weeks of ad-hoc parallel work, a team finds several half-set-up worktrees holding branches that cannot be deleted and whose purpose no one remembers. They need a decision framework to determine which worktrees should never have existed and to enforce teardown discipline.

A platform or developer-experience team codifies worktree decision rules into onboarding guides, linters, and pre-commit hooks to reduce branch collisions and abandoned checkouts across the organization. The value shows up as fewer lost hours debugging flaky parallel test runs.

A product that spins up isolated worktrees per agent session, parameterizes external singletons like ports and databases, and tears down environments automatically. Customers pay per concurrent agent or per managed workspace.
