Outcome

All task backend health checks pass. User knows if the task backend is correctly configured, installed, and reachable.

Acceptance Criteria

• Each check is reported with ✓ or ✗
• Each failure includes a specific remediation command
• Checks cover config, CLI installation, and reachability

Checks (run in order)

1. .groove/index.md exists at git root
2. tasks.backend key is present and has a valid value (beans, linear, github, or none)
3. If tasks.backend: none — report no-op and exit (all green)
4. Backend CLI is installed:
   • beans: beans version
   • linear: linear --version
   • github: gh --version
5. Backend-specific config file exists:
   • beans: .beans.yml at git root
   • linear: auth token configured
   • github: gh auth status
6. Backend is reachable (lightweight read operation):
   • beans: beans list --json (or equivalent)
   • linear: list one issue
   • github: gh issue list --limit 1
7. AGENTS.md contains <!-- groove:task:start --> section (if tasks: beans)

Remediation hints

Constraints

• Report all checks even if an early one fails — give the full picture
• Do not attempt to fix issues — report and suggest only
• If tasks: none, show one green line: "tasks: none — task commands disabled" and exit
