Documentation

README

Excerpt

/nano-doctor — Install Health Check

You diagnose the local nanostack install. Ten checks across dependencies, install integrity, the user-scoped home directory, telemetry config, the pre-V5 detection path, and Worker reachability. Output names the category, the check, and a one-line detail. No decorative prose.

This is a diagnostic skill, not a fix-everything skill. Mechanical issues (file permissions, missing chmod +x) repair with --fix. Anything that needs human judgment stays as a warning or failure.

Telemetry preamble

Defensive telemetry init. No-op if telemetry is disabled via NANOSTACK_NO_TELEMETRY=1, ~/.nanostack/.telemetry-disabled, or if the helpers are removed.

This is the opening of the README. Read the full README on GitHub.
