Tools

Create a detached session; names and path data are literalized before tmux expansion. Start a pane’s configured process; accepts no command payload.

Report liveness, tmux version, and the resolved socket when running. A daemon older than 3.3a is refused: upgrade tmux and restart the server, or stay on the previous libtmux release. Inspect tmux metadata; accepts no client-supplied executable input.

List stable session IDs, names, paths, and client counts. Inspect tmux metadata; accepts no client-supplied executable input.

Create a detached window; name and path data are literalized before tmux expansion. Start a pane’s configured process; accepts no command payload.

Return one session by stable ID or name. Inspect tmux metadata; accepts no client-supplied executable input.

Delete one session and every window it owns. Delete tmux state; accepts no command payload.

List windows through an exact owning session. Inspect tmux metadata; accepts no client-supplied executable input.

Replace one session name. Change tmux state; no client-supplied executable input.

Return one window by stable ID. Inspect tmux metadata; accepts no client-supplied executable input.

Delete one window and every pane it owns. Delete tmux state; accepts no command payload.

List every pane with stable pane, window, and session IDs. Inspect tmux metadata; accepts no client-supplied executable input.

Move a window to an exact index in its owning session. Change tmux state; no client-supplied executable input.

Replace one window name. Change tmux state; no client-supplied executable input.

Replace one window’s dimensions. Change tmux state; no client-supplied executable input.

Replace the pane layout of one window. Names and mirrored layouts follow the selected daemon version. Saved layouts accept v1 checksums and v2 JSON; v2 requires tmux 3.8-rc2 or newer. Change tmux state; no client-supplied executable input.

Make one window active. Change tmux state; no client-supplied executable input.

Create a configured-process pane; path data is literalized before tmux expansion. Start a pane’s configured process; accepts no command payload.

Return visible text, or retained history when requested. Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted.

Return bytes after a bounded client cursor and a replacement cursor. Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted.

Irreversibly discard retained scrollback for one pane. Delete tmux state; accepts no command payload.

Resolve coordinates using fixed tmux layout fields. Inspect tmux metadata; accepts no client-supplied executable input.

Return one pane by stable ID. Inspect tmux metadata; accepts no client-supplied executable input.

Delete one pane and its running process. Delete tmux state; accepts no command payload.

Require the target pane to be live and outside human-owned mode, then stage a private target-only buffer, optionally append Enter, paste it once, and verify cleanup. Empty text without Enter is a guarded buffer-free no-op. Send input to a pane’s program; a shell that receives it runs it with your user’s permissions.

Replace one or both pane dimensions. Change tmux state; no client-supplied executable input.

Restart only the pane’s configured process; no caller command is accepted. Start a pane’s configured process; accepts no command payload.

Require one live configured pane, outside human-owned mode and running a supported POSIX foreground shell, then send one command and return output after its private completion boundary. Run a shell command in a pane with your user’s permissions.

Search captured lines using a length-limited expression. Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted.

Make one pane active. Change tmux state; no client-supplied executable input.

Require every configured synchronized pane to be live and outside human-owned mode, then send one validated tmux key name. Send input to a pane’s program; a shell that receives it runs it with your user’s permissions.

Preflight each row’s configured synchronized pane cohort independently, requiring every pane to be live and outside human-owned mode before its text or key and optional Enter. Send input to a pane’s program; a shell that receives it runs it with your user’s permissions.

Replace one pane title. Change tmux state; no client-supplied executable input.

Set the inherited window synchronize-panes default; pane-level overrides determine effective synchronized input membership. Change tmux state; no client-supplied executable input.

Return pane metadata and visible terminal content from one call. Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted.

Exchange two pane positions without changing their IDs. Change tmux state; no client-supplied executable input.

Read configured hooks, optionally filtered by exact name. Read configured tmux commands; accepts no client-supplied executable input. Returned values may contain executable configuration.

Replace retained-history bounds with a non-negative integer. Change tmux state; no client-supplied executable input.

Replace the global mouse option with a typed boolean. Change tmux state; no client-supplied executable input.

Read global or session environment values. Read the tmux environment; accepts no client-supplied executable input. Returned values may contain secrets.

Read one exact option without accepting an option value. Read configured tmux commands; accepts no client-supplied executable input. Returned values may contain executable configuration.

Release or latch one named server-side channel. Change tmux state; no client-supplied executable input.

Wait for a named server-side channel with an optional deadline. Change tmux state; no client-supplied executable input.

Run up to sixteen declared inspect operations serially under this one call; inner operations receive no separate approval. Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted.

Expand only validated variable identifiers, never a caller format. Read configured tmux commands; accepts no client-supplied executable input. Returned values may contain executable configuration.

Discount this server’s pending input and recent submitted echoes; unmodelled keys stop tracking the current line. Wait for a new shell’s prompt before typing. matched_at_entry reports visible text at entry; a mode ending in -unconfirmed identifies input that was still unconfirmed at the deadline. Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted.
