Detect

This is the first step in LaunchDarkly's SDK onboarding workflow, designed to scan your repository and figure out what you're actually working with before attempting any installation. It walks through your project structure looking for telltale files like package.json, go.mod, or Cargo.toml to identify languages and frameworks, then detects package managers, checks for monorepo layouts, and finds application entrypoints. The detection is pretty thorough, covering everything from Next.js to Roku BrightScript. What I like is the confidence classification at the end: it won't forge ahead if it only finds weak evidence like a stray package.json with no actual app code. Instead, it stops and asks you to clarify, which beats the alternative of installing SDKs in the wrong place.
