Installation

Cargo

cargo install cuke-dedup

npm

In a JavaScript project, using Node.js 24 LTS (recommended):

npm install --save-dev cuke-dedup
npx cuke-dedup .

Node.js 20 remains the minimum compatible version and is tested in CI. Platform-specific native binaries are installed automatically as optional dependencies for macOS, Linux, and Windows on x64 and ARM64.

Building from source

Requires Rust 1.90 or newer:

cargo build --release --locked

GitHub Action

The Action downloads a native binary and verifies its checksum and build provenance — see CI and baselines.

Agent Skill

CukeDedup includes an Agent Skill for safely interpreting and remediating JSONL findings:

npx skills add figueiredoluiz/cuke-dedup --skill cuke-dedup

From a local checkout, use npx skills add ./skills --skill cuke-dedup. The installer can target supported coding agents or install globally; run npx skills add --help for agent and scope options. Invoke it as $cuke-dedup where supported, or ask the agent to analyze and safely fix duplicate Cucumber step definitions. The skill is distributed independently from the Cargo and npm packages.

Verifying a release

Release archives include SHA-256 checksums, keyless Sigstore bundles, and GitHub build provenance:

gh attestation verify <archive> \
  --repo figueiredoluiz/cuke-dedup \
  --signer-workflow figueiredoluiz/cuke-dedup/.github/workflows/release.yml

Published versions and release notes are maintained in GitHub Releases.
