Features
Subagents and workflow runs
Muse Code can fan work out to parallel subagents and run multi step workflows. In a terminal that is interleaved text. Helicon renders it as structure, so you can see which agents are running, cancel a workflow run, and skip or retry individual agents without restarting the thread.

The terminal problem
Seven agents writing to one stream is not a log, it is noise. The information is all there and none of it is legible. A replayable event log deserves a renderer.
What Helicon does with it
- Shows each subagent separately rather than interleaved.
- Cancels a workflow run without killing the whole thread.
- Skips an agent, or retries one that failed.
- Sends a running tool call to the background, stops one, or stops them all.
Why it stays honest
Helicon renders the protocol events Muse Code emits. It does not summarise them into something tidier, because the point of watching an agent is seeing what it really did.
Every feature here ships in the free Muse Code desktop app for Windows, macOS and Linux. Try Helicon in your browser on sample data, or install Helicon and point it at your own muse login.
Frequently asked questions
Can I stop one subagent without stopping the thread?
Yes. Individual agents in a workflow run can be skipped or retried, and a workflow run can be cancelled on its own.
Do subagents cost extra?
They use your Muse Code subscription like any other turn. Helicon shows what the thread would have cost at published rates so the fan out is visible.
Can I start a workflow from Helicon?
Workflow support tracks what the protocol exposes. Where Muse Code surfaces a run, Helicon renders and controls it.
