A practical guide to evaluating Ruby gems before adding them as dependencies. Covers five key areas: maintenance and activity (commit history, release dates, open issues), community and adoption (downloads, stars, contributors), licensing compatibility, security (vulnerability databases, supply chain risks, bundler-audit), and stability/fit (API maturity, documentation, right-sizing). Includes a seven-point checklist and tools like bundler-audit, license_finder, and Brakeman. Also raises the question of whether a gem is needed at all versus writing minimal code yourself.
