Installation

Packaged binaries are the recommended installation. They need Git 2.40 or newer; they do not need a local Go toolchain.

macOS and Linux

curl -fsSL https://githop.xyz/GnosysLabs/Hop/raw/branch/main/scripts/install.sh | sh

The installer:

  1. detects macOS/Linux and amd64/arm64;
  2. downloads the matching archive from the latest Gitea Release;
  3. downloads checksums.txt and verifies SHA-256 before extraction;
  4. installs the CLI to ~/.local/bin/hop;
  5. adds ~/.local/bin to .zprofile or .profile when necessary; and
  6. runs hop skill install --force to install the bundled agent integration.

The no-path skill command writes the same Hop-managed skill files to ~/.agents/skills/hop and ${CODEX_HOME:-~/.codex}/skills/hop. The second path supports Codex Desktop; compatible clients can use the shared .agents path.

Review before execution:

curl -fsSLO https://githop.xyz/GnosysLabs/Hop/raw/branch/main/scripts/install.sh
less install.sh
sh install.sh

Installer options are environment variables:

Variable Default Purpose
HOP_VERSION latest Release tag such as v0.1.0
HOP_INSTALL_DIR ~/.local/bin Binary destination
HOP_INSTALL_SKILL 1 Set to 0 for a CLI-only or custom integration
HOP_MODIFY_PATH 1 Set to 0 to leave shell profiles unchanged
HOP_GITEA_URL https://githop.xyz Gitea instance base URL
HOP_REPOSITORY GnosysLabs/Hop Alternate Gitea owner/repository

Example:

HOP_VERSION=v0.1.0 HOP_INSTALL_DIR="$HOME/bin" sh install.sh

Windows

In PowerShell as your normal user:

irm https://githop.xyz/GnosysLabs/Hop/raw/branch/main/scripts/install.ps1 | iex

The script verifies the Windows archive, installs to %LOCALAPPDATA%\Programs\Hop, updates the user PATH, and installs the shared and Codex-compatible skill bundles. To pin a version after downloading the script:

.\install.ps1 -Version v0.1.0

Use -SkipSkill for a CLI-only or separately managed integration. Use -SkipPath when another tool manages your PATH.

Go install

With Go 1.26 or newer:

go install githop.xyz/GnosysLabs/Hop/cmd/hop@latest
hop skill install --force

Put $(go env GOPATH)/bin on PATH if hop is not found. The second command installs both default skill bundles; omit it for a CLI-only installation.

Build from source

git clone https://githop.xyz/GnosysLabs/Hop.git
cd hop
go test ./...
go build -trimpath -o hop ./cmd/hop
mkdir -p "$HOME/.local/bin"
install -m 755 hop "$HOME/.local/bin/hop"
"$HOME/.local/bin/hop" skill install --force

Source builds are intended for contributors and as a pre-release fallback.

To install only one compatible runtime target, pass its parent skills directory:

hop skill install --path /path/to/agent/skills --force

Verify

hop version
hop help
git --version

Restart any agent client that was open while its skill bundle changed. See Getting started next.
