The "correct" way to have agents working on repositories in parallel - which you want to do to speed up AI development rather than just waiting around - is to use git worktrees, which are separate directories checking out different branches of a repo - so agents can work in parallel on different directories without interference. This also allows comparing different prompts, frameworks, agents etc.

But manually, I always found it hard to manage the complexity of creating a new branch, merging, propagating updates in time for the agents without creating a mess. So I created these super-simple wrapper functions to create a new "child" branch+worktree, runs pnpm install (which uses hardlinks to speed things up), merges from the parent worktree branch, merge to the parent worktree branch etc. This script also imposes a predictable directory structure on the worktrees, which allows understanding easily which task is the "parent" of another task.

The whole thing is a Claude skill. Check out the README.md and the skill description itself at https://github.com/qudent/parallel-working-made-simple/blob/... !
