Install Brig

One line, a checksum-verified prebuilt binary, no Rust toolchain — on macOS, Linux, or Windows. Then wire it into your agent with one command.

Pre-launch status: Brig ships as a verified prebuilt binary, published with each tagged release. The one-line installers below are the real install UX and go live the moment the first release is hosted.

macOS & Linux

Detects your CPU, downloads the right binary, verifies its SHA-256, and puts brig on your PATH.

# installs a verified binary — no Rust needed curl -fsSL https://get.osnavi.com/brig/install.sh | sh

Cautious (recommended for any curl | sh) — read it first, then run:

curl -fsSL https://get.osnavi.com/brig/install.sh -o install.sh less install.sh # inspect it sh install.sh

Windows

PowerShell:

irm https://get.osnavi.com/brig/install.ps1 | iex

Or download a binary directly

Each release publishes a signed checksum (SHA256SUMS) next to the binaries.

Platform	File
macOS · Apple Silicon	brig-0.2.0-aarch64-apple-darwin
macOS · Intel	brig-0.2.0-x86_64-apple-darwin
Linux · x86_64	brig-0.2.0-x86_64-unknown-linux-musl
Linux · arm64	brig-0.2.0-aarch64-unknown-linux-musl
Windows · x64	brig-0.2.0-x86_64-pc-windows-msvc.exe

Verify what you ran: the installer aborts on any checksum mismatch, and you can re-check by hand — shasum -a 256 brig (macOS) / sha256sum brig (Linux) against the published SHA256SUMS. It's a security tool; treat its supply chain like one.

Then: wire it into your agent

One command configures the pre-tool hook for your harness — no JSON to hand-edit.

brig init claude-code # also: opencode · pi · hermes

Start in ride-along (logs everything, blocks nothing), then turn up the protection. Verified end-to-end against Claude Code · OpenCode · Pi · Hermes.
