Drive build systems and package managers, Maven, Gradle, npm, pnpm, yarn, and Cargo, through the devtools-mcp backends without drowning in output. Use to build/test a project, inspect its dependency tree and SUBDEPENDENCIES (versions, depth, conflicts), synchronize/resolve/install deps, run a security audit, find outdated packages, or list runnable tasks/scripts. One verb vocabulary across every language; output is a bounded summary + a queryable Polars frame.
