description: Diagnose a plugin-installed AgentHub — Node, npm, disk, bootstrap, server, hooks, CLI, systemd, tmux, UI build
---

Run the diagnostic and report what it found. Do not fix anything unless the user
asks.

```bash
node "${CLAUDE_PLUGIN_ROOT}/scripts/plugin-doctor.js"
```

Print the output verbatim, then add at most three lines of guidance based on the
`FAIL` and `WARN` rows:

- `FAIL Node` → the installed Node is too old for `node:sqlite`; the server
  cannot start until Node is upgraded.
- `FAIL Hooks` → duplicate hook entries double every token and cost figure.
  Starting a new Claude Code session removes them automatically (the bootstrap
  backs the file up as `settings.json.agenthub-bak` first).
- `FAIL Server` → run `/agenthub-update`, then check
  `~/.claude/agenthub/runtime/bootstrap.log` and `server.log`.
- `FAIL Runtime deps` → the install is incomplete, not merely absent. Delete
  `~/.claude/agenthub/runtime/node_modules` before running `/agenthub-update`;
  reinstalling over the broken tree is what let it survive.
- `FAIL npm` or `FAIL Disk` → nothing else in the report can be trusted until
  these are fixed; both silently truncate installs.
- `WARN agenthub CLI` → print the exact `export PATH=...` line from the output.
- `WARN systemd` → when it says the unit names a **previous plugin version**,
  the dashboard is running now but will NOT come back after a reboot. Starting
  a new Claude Code session repairs it; print the `--force` command from the
  output as the immediate fix. "installed but not running" just needs
  `systemctl --user start agenthub`.
- `WARN tmux` → only the run console, `agenthub lanes shell` and the
  session-reload keystrokes are affected; monitoring, workspaces and the CLI are not.
  Print the install command from the output. If the row says `ok` but Start Run
  still fails, the server has a different PATH than this check — ask it directly
  with `curl -s localhost:4820/api/run/tmux`.
- `WARN Dashboard UI` → run `/agenthub-open` to build the bundle. When the row
  quotes a build error, report that error — it is the actual problem.

No preamble, no summary of things that passed.
