Diagnose and fix tabby when something about it isn't working — tab names or colors missing, /tab not responding, Tabby Island not showing or not listing sessions, no macOS permission prompt, tiling or the watermark doing nothing, "fix tabby", "tabby is broken". Runs `tabby doctor --json` and works through its fixes with the person.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fix tabby
1. Run the check (10-minute timeout on every Bash call):
```sh
sh "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/tabby/bin/tabby" doctor --json
```
If that file doesn't exist, setup never ran: use `sh "<this skill's base directory>/../../bin/tabby.sh" doctor --json` instead.
2. It returns `{ ok, next, reinstall, checks: [{ id, title, status, detail, fix }] }`. Work through each `fail`, then each `warn`, that has a `fix`:
- `fix.run`: run it (tabby's own commands; `sh "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/tabby/bin/tabby" …`).
- `fix.tell`: tell the person what to do, in your own words, and wait for them. Never accept tabby's terms for them: show the summary (`… tabby terms`) and ask first.
Run it again until nothing is `fail`, and tell them in a line or two what was wrong and what changed.
3. Outdated (the `update` check, or the island is older than tabby): `… tabby update` gets the newest plugin, refreshes setup and updates Tabby Island. Then open sessions need `/reload-plugins`.
…Read the whole file at its exact version.
How to install
mdr add 0xntive/tabby/doctor@sha256:7961b54222cf92cdThe line at the top of this page pins the label git:20261012.6239b11, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
