# Doctor A read-only health check for radin's own install under `~/.claude`. It confirms that every skill and lib file `install.sh` copies is present, checks that radin's own lib shell scripts have valid syntax, and reports which optional companion tools (rtk, code-review-graph, caveman, ponytail) are currently reachable. It never mutates anything, which mirrors `install.sh`'s own "advisory only" stance on companion tools. ## Step 1: Run it ```bash RADIN_CLI doctor ``` ## Step 2: Report it Print the full output to the user as-is. It already lists every checked item with its status. A non-zero exit means one or more expected files are missing or have invalid syntax. Tell the user to re-run `install.sh` (or `radin-update`) to fix it. A missing companion tool is advisory only, never a failure, so it does not need that remediation.
