git-parsec

Git worktree lifecycle manager for parallel AI agent workflows

parsec manages isolated git worktrees tied to tickets (Jira, GitHub Issues), enabling multiple AI agents or developers to work on the same repository in parallel without lock conflicts.

demo

The Problem

Git uses a single working directory with a single index.lock. When multiple AI agents (or developers) try to work on the same repo simultaneously:

git add/commit operations collide on .git/index.lock
Context switching between tasks requires stashing or committing WIP
Worktrees exist but have poor lifecycle management
No connection between tickets and working directories

The Solution

# Create isolated workspaces for two tickets
$ parsec start PROJ-1234 --title "Add user authentication"
Created workspace for PROJ-1234 at /home/user/myapp.PROJ-1234
  Add user authentication

$ parsec start PROJ-5678 --title "Fix payment timeout"
Created workspace for PROJ-5678 at /home/user/myapp.PROJ-5678
  Fix payment timeout

# See all active workspaces

parsec undo [--dry-run]

Option	Description
`--dry-run`	Preview what would be undone

# Preview
$ parsec undo --dry-run

  Would remove worktree at /home/user/myapp.PROJ-5678
  Would delete branch 'feature/PROJ-5678'

# Execute
$ parsec undo
Undid start for PROJ-5678
  Worktree removed.

# Nothing to undo
$ parsec undo
Error: nothing to undo. Run `parsec log` to see operation history.

`parsec config`

# Interactive setup wizard
$ parsec config init

# Show current configuration
$ parsec config show
[workspace]
  layout          = sibling
  base_dir        = .parsec/workspaces
  branch_prefix   = feature/

[tracker]
  provider       = jira
  jira.base_url  = https://yourcompany.atlassian.net

[ship]
  auto_pr         = true
  auto_cleanup    = true
  draft           = false

# Output shell integration script
$ parsec config shell zsh

Global Flags

These flags work on every command:

Flag	Description
`--json`	Machine-readable JSON output
`-q, --quiet`	Suppress non-essential output
`--repo <path>`	Target a different repository

$ parsec list --json
$ parsec ship PROJ-1234 --quiet
$ parsec status --repo /path/to/other-repo

Shell Integration

parsec switch prints a path but cannot cd for you. The shell integration wraps parsec switch so it changes your directory automatically:

# Add to ~/.zshrc
eval "$(parsec config shell zsh)"

# Or for bash, add to ~/.bashrc
eval "$(parsec config shell bash)"

After sourcing, parsec switch <ticket> will cd into the worktree directly:

$ parsec switch PROJ-1234
# Now you're in /home/user/myapp.PROJ-1234

Configuration

Config file: ~/.config/parsec/config.toml

[workspace]
# "sibling" (default) creates worktrees next to repo: ../repo.ticket/
# "internal" creates inside repo: .parsec/workspaces/ticket/
layout = "sibling"
base_dir = ".parsec/workspaces"
branch_prefix = "feature/"

[tracker]
# "jira" | "github" | "gitlab" | "none"
provider = "jira"

[tracker.jira]
base_url = "https://yourcompany.atlassian.net"
# Auth: PARSEC_JIRA_TOKEN or JIRA_PAT env var

[tracker.gitlab]
base_url = "https://gitlab.com"
# Auth: PARSEC_GITLAB_TOKEN env var

[ship]
auto_pr = true        # Create PR/MR on ship
auto_cleanup = true   # Remove worktree after ship
draft = false         # Create PRs as drafts

[hooks]
# Commands to run in new worktrees after creation
post_create = ["npm install"]
