yoo: a local-first CLI doctor for rapid project and environment audits
Reads project files, Git metadata, and installed tooling to produce an instant terminal audit: the core capability is the yoo doctor command that inspects repositories and toolchains. Nihitdev builds this Windows utility as a Rust single-binary tool in the utilities-tools category, with JSON output and configurable terminal themes. It suits developers and DevOps engineers who want fast, privacy-focused environment checks directly in the terminal without cloud services.
What does yoo actually check in a project and environment?
yoo parses local project files, inspects Git state, and queries installed development tools to report configuration and toolchain health. The tool emits stable JSON via a --json flag for script integration and prints human-readable summaries in the terminal. Its theme options (Dracula, Nord, Gruvbox and others) change output colors but do not affect the diagnostic content. The command named yoo doctor runs the main suite of checks.
Does yoo slow down your system while it runs?
yoo is written in Rust and distributes as a single binary, which reduces runtime overhead compared with multi-process toolchains. Because it reads local files and Git metadata without network calls, runtime is bounded by repository size and disk speed rather than network latency. The local-first design means no background daemon; diagnostics run on demand, so CPU and RAM impact occur only during the active command execution.
Is it safe to run on a production machine?
yoo operates without sending data externally, following a local-first, no-telemetry model; project data is not uploaded and no account is required. The tool reads files and Git metadata for analysis rather than writing system configuration, which reduces the chance of unintended changes. For environments that require write prevention, run the doctor command in read-only directories or inside a container to avoid any local edits from other processes during inspection.
Do I need technical knowledge to use yoo effectively?
The CLI exposes a single diagnostic workflow that suits engineers comfortable with terminals: install via package managers and run yoo doctor or append --json for automation. The JSON output supports piping into other scripts for CI checks. Casual users unfamiliar with terminals will face a learning curve because the interface assumes knowledge of Git and local toolchains rather than offering a graphical wizard.
yoo serves developers who need fast, private diagnostics; recommended for technical users
yoo is a practical, locally run diagnostic tool for developers and Ops staff who must verify repository and toolchain health without outbound telemetry. The Rust single-binary approach keeps execution compact and the JSON output makes automation straightforward. Expect a terminal-first workflow: the tool favors users who can interpret Git state and integrate JSON results into scripts. Recommended.
