Depsguard

DepsGuard

DepsGuard is a zero-dependency Rust CLI that scans package manager configs for supply chain security best practices and offers interactive fixes. It targets Linux, macOS, and Windows, and supports npm, pnpm, yarn, bun, and uv.

When to use this skill

Use this skill when an agent or user needs to:

• Audit a project's .npmrc, .yarnrc.yml, bunfig.toml, pnpm-workspace.yaml, uv.toml, or related package manager configuration for hardening gaps.
• Apply recommended supply chain security settings (e.g. lockfile enforcement, provenance checks, registry pinning) to an existing project.
• Install DepsGuard as part of a developer onboarding or CI pipeline.

Install

Homebrew (macOS / Linux)

brew tap arnica/depsguard https://github.com/arnica/depsguard
brew install depsguard

APT (Debian / Ubuntu)

sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://depsguard.com/apt/gpg.key \
  | sudo gpg --dearmor -o /etc/apt/keyrings/depsguard.gpg
echo "deb [arch=amd64,arm64 signed-by=/etc/apt/keyrings/depsguard.gpg] https://depsguard.com/apt stable main" \
  | sudo tee /etc/apt/sources.list.d/depsguard.list >/dev/null
sudo apt update
sudo apt install depsguard

Scoop (Windows)

scoop bucket add depsguard https://github.com/arnica/depsguard

Usage

Run in the root of a project:

depsguard

DepsGuard will detect the package managers in use, list hardening findings, and prompt you interactively to apply fixes. Use depsguard --help for flags.

Notes for agents

• DepsGuard has zero runtime dependencies; the binary is self-contained.
• It only reads and writes files under the current working directory (and the user's home directory for shell / package manager rc files when explicitly permitted).
• It is safe to run in CI in a dry-run / check-only mode for drift detection.
