doctor

From README

TinyFish Doctor tinyfish doctor (CLI 0.22+) owns the diagnosis. Your job is to run it, do the one check it structurally cannot do, and act on what comes back. Never hand-edit config files — every repair goes through the CLI, which carries backup and merge rigor. No shell? Sandboxed surfaces (Claude.ai, Desktop, Cowork) have no npx. If you cannot run commands, skip to step 2 — it is the more valuable check anyway — then give the user the command from step 1 to run themselves. Run doctor JSON on stdout: schemaversion, cliversion, okharnesses, okcli, checks[], harnesses[], repairs[]. Read schemaversion before the fields. This skill describes 3 (CLI 0.22+). The command pins @latest, so a newer CLI can hand you a shape you do not know: above 3, stop reading fields, show the user --pretty output instead, and rely on step 2 for the verdict. Below 3 a single ok replaces the two verdicts and checks[] carry no scope, so read only checks[] and the exit code there. Two verdicts, not one.
