> Start a pane's configured process; accepts no command payload. Only restarts a pane whose command has ALREADY EXITED. killExistingProcess overrides that and kills what is running first — an editor holding unsaved changes, a build part way through. It reruns the command the pane was created with rather than running something new.

Server behavior and tool contracts may change. Tool availability depends on the server configuration.

Start a pane’s configured process; accepts no command payload. Only restarts a pane whose command has ALREADY EXITED. killExistingProcess overrides that and kills what is running first — an editor holding unsaved changes, a build part way through. It reruns the command the pane was created with rather than running something new.
