directories, or alter agent/SSH settings. Unreleased v1.4.0 candidate (#358): `doctor --agent NAME` restricts checks and declared agent capabilities to the selected registered agent, including execution over SSH. It also skips the shared installed-skill inventory. `doctor --agent codex --selected-home-only --codex-home /absolute/home` checks only the selected Codex home and skips the inventory of other homes. These options do not enable reverse-route checks. Without them, existing all-agent and bounded multi-home diagnostics keep their behavior. +The candidate MCP wrapper supports only the following checks and effects: + +| Mode / agent | Checked facts | Process / connection effects | +| --- | --- | --- | +| Metadata | Policy and adapter declarations | None | +| Active Claude | Registry records, process identity metadata and filesystem inbox presence | No inbox connection | +| Active Codex | Executable presence, selected-home read-only SQLite queries and bounded writer scan | No native Codex execution or version query | +| Active Antigravity | Registered bridge metadata | No bridge or native RPC | +| Active SSH | Configured forward route, only after explicit probe permission | SSH configuration may execute commands; no reverse probe or automatic connection back to a return host | + +Representative allowlisted codes include `sessions_dir_missing`, `inbox_present`, `codex_executable_missing`, `state_db_readable`, `unsaved_writer_check_unavailable` and `adapter_failed`.

A complete `missing_home` result can have `ok=true`; read each agent's status separately. `diagnosticEvidence` is `point_in_time_only` for active results and `not_collected` in metadata mode. `readiness` remains `not_checked` because no per-target readiness is tested. A passing `state_db_readable` check means only that the read-only database query succeeded; it is not an effective-storage attestation or a return-route guarantee. + +The stages `tcpAccept`, `tls` and `peerAuthentication` remain `not_checked`. Here `peerAuthentication` refers to paired-device authentication, separate from forward SSH authentication. `sshFailure` reports only a sanitized forward SSH failure category, such as `authentication_failed` or `host_key_failed`.
