Quality and Tooling

Quality and tooling choices decide how the generated project is checked, documented, and maintained.

Testing

TypeScript testing choices include Vitest, Playwright, Vitest plus Playwright, Jest, Cypress, or none.

Other ecosystems expose their native testing paths, such as Rust testing libraries, Python quality tools, Java testing libraries, Elixir ExUnit/Mox/Bypass/Wallaby choices, and mobile testing with Maestro or React Native Testing Library.

Logging and observability

Logging and observability can be stack-specific. TypeScript has Pino, Winston, Evlog, OpenTelemetry, Sentry, and Grafana choices. Go and Rust have dedicated logging categories. Java and Elixir expose observability-related libraries through their ecosystem options.

Code quality and docs

Code quality choices include Biome, Oxlint, Ultracite, Lefthook, Husky, and Ruler. Documentation addons include Starlight and Fumadocs where compatible.

Project workflow

Package manager, version channel, AI docs, Git initialization, install behavior, --dry-run, and --verify all belong to the workflow layer rather than the generated app runtime.
