wsp send

usage: wsp send <thread> [--model, --effort <value>] [--fast] [--file <path>]
       [--detach] "<message>"
  a message to the thread, on a named model or effort, fast or not, with files;
  the thread keeps its own access and a running turn its own picks; --detach
  prints the id and returns

  --model     the model the turn runs on, by the agent's own slug
              (claude-sonnet-5); the thread's own without it
  --effort    how hard the agent thinks, by its own word (low, medium, high,
              xhigh, max); absent on a new thread means the agent's default; on
              send, the thread's own
  --fast      run the turn in the agent's fast mode, on a model that offers one;
              refused naming the model otherwise
  --file      a file on this computer to send with the message: an image goes as
              an image, any other file lands in the thread's folder and the
              message names its path; repeats
  --detach    print the thread's id and return, leaving the reply to the
              thread's finished line
  --json      print the raw protocol values, one JSON object per line, with
              everything else on stderr
  --state     the state file the host serves
  --host      run the line against a host on your account, by the name wsp hosts
              lists it under; WSP_HOST names one for a whole shell
