Spike result (probed claude 2.1.175 over stream-json): there is NO
set_effort/set_thinking_effort control subtype — both are rejected. The
lever is the `--effort <level>` spawn flag (low/medium/high/xhigh/max;
settings.json effortLevel is the persisted default). So changing effort
restarts the process: respawn-with-resume keeps the conversation and
carries the flag — the same continuity /clear and /resume already rely on.
- SpawnSpec.effort → orchestrator appends `--effort <level>`.
- claude_pane: /effort <level> validates and respawns (toast explains the
restart); bare /effort opens a picker; the pane re-applies its effort on
every later respawn. Invalid level → local notice listing levels.
- ModelPickerCard generalised minimally (title + isCurrent predicate) so
the effort picker reuses it; effort needs exact matching because `high`
is a substring of `xhigh` and alias-containment would mis-mark it.
- SessionStatus.effort + StreamJsonSession.noteEffort: the wire never
reports effort, so the spawner records what it set; status/sidebar read
it from the normal status stream.
- Routing: effort moves from the TUI-only catalog to kClideOwnedCommands.

Typed into the conversation view, /model was forwarded to the session's
stdin as message text — the CLI's interactive picker only exists in its
own TUI, so nothing happened. clide now owns it like /clear//resume//fork
(T-156).
/model <name> sends a set_model control_request (verified against
claude 2.1.175: subtype accepted alongside set_permission_mode;
"default" resets to the CLI's configured model) with an optimistic
status merge, rolled back with a toast if the CLI rejects the name.
Bare /model swaps a picker card into the interaction zone (D-78) —
numbers / arrows + Enter / Esc, mirroring the prompt card's shortcuts.
The model list comes from the `initialize` handshake response, which
the session now always sends — the spike verified it is side-effect-
free, and it previously went out only when MCP servers were hosted.
Until the response lands the picker falls back to the stable aliases.
