{"name":"\/effort","slug":"effort","family":"slash","title":"Slash commands","noun":"slash command","description":"Set the [effort level](\/docs\/en\/model-config#adjust-effort-level): `low` to `xhigh`, `max`, [`ultracode`](\/docs\/en\/workflows#let-claude-decide-with-ultracode), or `auto`; `status` prints it. `max` and `ultracode` are session-only; the [`ultracode`](\/docs\/en\/settings-reference#ultracode) key persists. Run it while Claude is responding and, once you confirm the [cache warning](\/docs\/en\/prompt-caching#changing-effort-level), if Claude Code shows one, Claude Code applies the new level to the next request in that turn. Before v2.1.242, Claude Code decided from a feature flag it fetched from Anthropic whether to run the command mid-turn or queue it until the turn finished, and always queued it in a session that doesn't [fetch feature flags](\/docs\/en\/env-vars#features-that-need-feature-flag-fetching), such as on a [third-party provider](\/docs\/en\/third-party-integrations).
