Devstart CLI is a TypeScript tool that scaffolds working branches and git worktrees straight from GitHub Issues or PRs, then starts your preferred editor or automation runner. All you need locally is node + pnpm.

日本語ドキュメントは README.ja.md を参照してください。

• devstart <issue|pr> automatically creates issue/<number> branches or reuses the PR head
• devstart issues / devstart prs offers an interactive picker (requires the gh CLI)
• Places git worktrees under <repo>.worktrees/, with --in-place to reuse the current clone
• Launches VS Code or Cursor, and forwards custom arguments to codex / claude runners

pnpm install

• Recommend Node.js 18+ and pnpm 10.18+
• Assumes gh auth status and git worktree list succeed on your machine

pnpm build   # TypeScript -> dist/
pnpm test    # Vitest
pnpm start -- --help  # Inspect the CLI help with the latest build

Always run pnpm build to emit dist/index.js before invoking pnpm start.

pnpm start -- --help
# Example: interactively pick an issue and open VS Code
pnpm start -- issues --vsc
# Example: switch branches in the existing repo without a worktree
pnpm start -- 123 --in-place
# Example: run with codex runner and forward extra arguments
pnpm start -- 456 --codex=--model=gpt-4 --codex-arg "--max-tokens=2000"

Common flags:

• --vsc, --cursor: open the prepared worktree in the specified editor
• --codex[=value], --claude[=value]: enable runners and set their primary argument
• --codex-arg <value>, --claude-arg <value>: pass additional runner arguments (repeatable)
• --shell[=path], --shell-arg <value>: launch an interactive shell inside the worktree (defaults to $DEVSTART_SHELL, $SHELL, or /bin/bash)
• --version, -V: print the CLI version and exit
• --in-place: skip creating a worktree and only switch the current repo branch

1. Run pnpm build && pnpm test
2. Apply your changes inside the worktree, then rerun devstart to relaunch runners or editors
3. Commit with Conventional Commit prefixes (e.g., feat: ..., fix: ...)
