# /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. ```bash _P="$HOME/.claude/skills/nanostack/bin/lib/skill-preamble.sh" [ -f "$_P" ] && . "$_P" nano-doctor unset _P ``` ## Process Run the health check script, then summarize what the user actually needs to do: ```bash ~/.claude/skills/nanostack/bin/nano-doctor.sh ``` Optional flags: - `--json` — machine-readable output. Use when invoked by another tool or when piping to `jq`. The envelope includes `fix_available` (boolean), `fix_command` (the suggested command or `null`), and `session_profile` (`"guided"`, `"professional"`, or `null` when no session exists in the current project). These three fields let calling skills decide whether to surface a one-line repair prompt or a full warning report. - `--offline` — skip Worker reachability. Use in air-gapped environments or during CI. - `--fi...
