Slash commands

Slash commands run inside the TUI before a message is sent to the model.

Common commands:

/model chooses a model for the current session from saved choices.
/model <provider/model> selects an exact model directly, even if it is not in saved choices.
/model all [search] browses OpenRouter models, adds one to the global choices catalog, and selects it for the current session.
/connect connects a model provider.
/effort shows the current reasoning effort and accepted values.
/effort <none|minimal|low|medium|high|xhigh|max> sets a session override for the active model provider.
/effort clear or /effort default removes the session override so the configured effort or provider default applies.
/reasoning is an alias for /effort.
/new clears the terminal and starts a fresh project-local session.
/fork clones the current session into a new project-local session and switches to it.
/queue <prompt> queues a follow-up prompt, or starts it immediately when idle.
/q <prompt> is a short alias for /queue.
/steer <prompt> sends best-effort guidance to the active turn, falling back to a queued follow-up if it is not consumed.
/skills opens the Skills overlay.
/skills list prints available skills.
/skills inspect <name> shows one SKILL.md.
/skill <name> [instruction] activates a skill.
/kb status shows files that are not current in the knowledge base.
/kb sync processes non-clean files into L1 knowledge entries.
/kb sync --full processes all in-scope project files.
/kb init creates Topchester project knowledge folders.
/kb reset deletes the local knowledge base and cache.

The first slash in a direct model reference separates the provider from the full model ID. For example, /model openrouter/google/gemini-3.1-flash-lite selects provider openrouter and model google/gemini-3.1-flash-lite. Built-in OpenRouter and Codex references do not need saved provider config. Custom providers still do.

none is an explicit reasoning effort value. Use clear or default when you want to remove the session override instead. Model and effort overrides survive resume, restore, and fork; /new returns to JSONC defaults.

Type /effort or /reasoning with a trailing space to list all accepted effort values in the suggestion panel. Continue typing to narrow the list, then press Tab to complete the selected value.

/model, /connect, /effort, /reasoning, /new, /fork, /restore, /queue, /q, and /steer are TUI-only. In topchester run, Topchester prints a short message that says to use the interactive TUI.
