wh: the tiny git companion for coding agents

Field notes

wh organizes agent work around sibling Git worktrees, copying .env files while anchoring each branch to the main worktree. Its routine commands return machine-readable state, support dry-run cleanup, and can remove merged branches without touching dirty worktrees. The project is a 0.6 MiB Rust binary with no runtime dependency, while its optional explanation layer works with Anthropic, OpenAI, Groq, or local Ollama models. The page also documents a Claude Code hook and reports a five-versus-nine-turn cleanup comparison.
