How pf works

There have been many attempts to nail a DX for parallel work in the agentic coding era. Most are thin wrappers over git worktree. Instead pf introduces a new paradigm: the workshell.

A _workshell_ is an ephemeral worktree whose lifecycle is bound to a subshell.

Here's how it works (key points in bold).

- You open a Git branch with pf open or create a new one with pf new .
- An ephemeral worktree is created for this branch (in .git/pf/worktrees) and opened in a fresh subshell.
- You are now in an fresh checkout of your repo that is isolated on disk. Make changes with your agent/editor of choice and commit them.
- You close the subshell with pf close. The associated worktree is auto-pruned.
- Your changes still exist on the associated branch, as Git commits/branches are shared among all worktrees. The worktree is destroyed—but your commits aren't.




Features

This approach has some nice properties.

- 🖥️ Tab-local workspaces — Normally a git checkout/git switch changes your active branch for all terminals. With workshells, you can functionality open branches in the current tab only.
- 🌳 Full isolation — Each workshell is isolated on disk, so the changes you make don't interfere anything else you're doing.
- 🙅‍♂️ Never stash again — You can pf open a branch even with uncommitted changes. When you exit the subshell, things will be exactly the same as they were. ☕️
- 🪾 Consistent with branch semantics — As with regular git switch, pf close won't let you close the subshell if you have unstaged/uncommitted changes. This is a feature, not a bug! Regular worktrees make it easy to lose your work in a forgotten corner of your file system.
- 🤖 Agent-ready — Spin up parallel workshells so multiple agents can work simultaneously without conflicts.




Quickstart

This section is entirely linear and self-contained. Try running all these commands in order to get a feel for how pf works. First, install pf.

`bash
$ npm i -g pf
`




Then clone a repo (any repo works):

`bash
$ git clone git@github.com:colinhacks/zod.git
$ cd zod
`




After cloning, the main branch is checked out. Let's say we want to start work on a new feature:

`bash
$ pf new feat-1

✓ feat-1 (from main)
Opened branch in ephemeral subshell at .git/pf/worktrees/zod@feat-1
Type 'pf close' to return.
`




You're now in a workshell. Check where you are:

`bash
$ pwd
/Users/colinmcd94/Documents/repos/zod/.git/pf/worktrees/zod@feat-1

$ git branch --show-current
feat-1
`




Now let's make some changes. (You can also open the repo in an IDE, start an agent run, etc.)

`bash
$ touch a.txt
`




Now let's try to close the workshell.

`bash
$ pf close
⚠ Uncommitted changes found. Commit, stash, or reset your changes first.
Or use --force/-f to discard changes
pf close -f
`




We aren't able to close because we have uncommitted changes. Let's commit them.

`bash
$ git add -A && git commit -am "Add a.txt"
`




Now we can try closing again. Since our changes can be fast-forwarded from the base branch, pf offers to auto-merge the changes.

`bash
$ pf close
✓ Back in main
Pruned worktree. Your changes are still in the 'feat-1' branch.
To merge your changes:
git merge feat-1

Auto-merge? (y/n/never) y

✓ Merged 'feat-1' into 'main'
`




CLI

`sh
pf v0.x.y - Human- and agent-friendly Git multitasking

Usage: pf [options]

Commands:
new [branch] Create a branch and open it [--from ]
open Open a branch in a workshell
close Exit current workshell
ls List orphaned worktrees
status Show current branch
rm Remove a branch's worktree
config Show or create config file

Options:
--help, -h Show help
--version, -v Show version
`




$3

Normally the worktree will be auto-pruned when you close its associated workshell. If a worktree is left behind for some reason, you can list them with pf ls.

`sh
$ pf ls
┌────────┬───────────┬───────────────┐
│ branch │ status │ created │
├────────┼───────────┼───────────────┤
│ main * │ clean │ - │
│ feat-1 │ 1 changed │ 5 minutes ago │
└────────┴───────────┴───────────────┘
`







$3

You can open any existing Git branch in a workshell.

`sh
$ pf open feat-1

✓ feat-1 (existing worktree)
Type 'pf close' to return.
`




$3

`sh
$ pf status
branch: main (root)
worktree: /path/to/zod
status: clean
`




$3

Remove the worktree for a branch (the branch itself is kept):

`sh
$ pf rm feat-1

✓ Pruned worktree for feat-1
`




$3

This closes the current workshell and auto-prunes the associated worktree. Your changes survive in your branch commits.

`sh
$ pf close
✓ Back in main
Pruned worktree. Your changes are still in the 'feat-1' branch.
To merge your changes:
git merge feat-1

Auto-merge? (y/n/never) y

✓ Merged 'feat-1' into 'main'
`

If the branch hasn't been pushed to a remote, you'll be prompted to auto-merge:

- y — merge into base branch
- n — skip (branch is kept, merge manually later)
- never — permanently disable auto-merge prompt

That command will fail if you have unstaged/uncommited changes. Use the --force/-f flag to force close the workshell; this will discard uncommitted changes.

`sh
$ pf close --force
`




$3

To print or create a config file:

`sh
$ pf config

✓ Config file: /path/to/repo/.git/pf.toml

────────────────────────────────────────────────────────────
setup = "npm install"
────────────────────────────────────────────────────────────
`

If no config exists, you'll be prompted to create one.

`sh
$ pf config

No config file found.

Where would you like to create one?
1. .git/pf.toml (local only, not committed)
2. pf.toml (project root, can be committed)

Choice (1/2): 1

✓ Created /path/to/repo/.git/pf.toml
`




pf.toml

You can configure pf with a pf.toml file. This is useful for running setup scripts when opening a workshell (e.g., npm install).

pf looks for config files in the following order:

| Path | Description |
|------|-------------|
| .git/pf.toml | Local only, not committed (highest precedence) |
| pf.toml | Project root, can be committed |




`toml


setup script executed in subshell after initialization


setup = "npm install && cp {{ repo_path }}/.env {{ worktree_path }}/.env"
`

The following variable substitutions are supported in setup.

| Variable | Description | Example |
|----------|-------------|---------|
| {{ branch }} | Branch name | feature/auth |
| {{ worktree_path }} | Absolute path to worktree | /path/to/repo/.git/pf/worktrees/repo@feat |
| {{ repo_path }} | Absolute path to main repo | /path/to/repo` |
