Does acp supports background Bash/Task?

[femto]

recent claude code has background Bash/Task support,
using BashOutput to get background bash output,
using TaskOutput to get background task output(I believe).
Does acp supports background Bash/Task,
it seemed current acp only has foreground bash?

I'm not sure what you mean? I think this is mostly representing tool outputs no?

[femto]

Does the ACP spec define how run_in_background should be represented?
currently claude-agent-acp doesn't seem to use terminal/create,
and for task output, you mean just call TaskOutput tool(in claude code) to get result?
It seemed quite confusing.

Also, I check it for every 5 seconds,

It seemed pretty "claude code" heavy, since claude code give background task a hex id bc9m8elbq,
and and uses tail -f /private/tmp/claude-501
/ -Users-femtozheng-python-project-minion-code/tasks/bc9m8elbq.output
for checking, which is just confusing.
(I think currently claude-agent-acp converts foreground bash to terminal type of output:
in tools.ts:

if (supportsTerminalOutput) {
    return { content: [{ type: "terminal", terminalId }], _meta: {...} };
  }

I see yeah this seems more like an issue of claude agent adapter issue

[femto]

ok. currently claude code can press UP and DOWN to switch between background
tasks and see its output, what do you think about that?

You can find MPC/ACP workers which can help you to run bash scripts in ACP repos by default. I set optional file system tuning switch, and other elements logic to @stdiobus/workers-registry. It woks well.
