git-hunk

git-hunk is a small Rust CLI for non-interactive hunk staging.

It is meant for AI agents and other tooling that need an agent-safe replacement for git add -p so they can make atomic commits from Bash.

Install

Install from crates.io after the first publish:

cargo install git-hunk

Install directly from GitHub at any time:

cargo install --git https://github.com/nexxeln/git-hunk.git

After the first GitHub release exists, install the latest binary with:

curl -fsSL https://raw.githubusercontent.com/nexxeln/git-hunk/main/install.sh | sh

Install a specific version:

curl -fsSL https://raw.githubusercontent.com/nexxeln/git-hunk/main/install.sh | GIT_HUNK_VERSION=0.1.0 sh

The installer currently supports:

macOS aarch64
macOS x86_64
Linux x86_64

Commands

scan lists selectable hunks and change blocks and returns a snapshot_id
show prints a hunk or change with line numbers
stage stages selected hunks, changes, or line ranges
unstage removes selected hunks, changes, or line ranges from the index
commit stages a selection and commits it in one step

Build

cargo build

Release

On every push to main, GitHub Actions runs tests, publishes a new crates.io version when Cargo.toml has an unpublished version, and creates a matching GitHub release with binary archives.

Example

git-hunk scan --mode stage --json
git-hunk show --mode stage <hunk-id>
git-hunk stage --snapshot <snapshot-id> --hunk <hunk-id>:new:41-44
git-hunk commit -m "feat: split atomic change" --snapshot <snapshot-id> --change <change-id>

Notes

Mutating commands require a fresh snapshot_id
Rescan after every successful stage, unstage, or commit
Unsupported paths like conflicts, renames, and binary diffs are reported instead of forced through

See SKILL.md for the agent workflow and selector syntax.
