**Muse Spark Code** puts Meta's Muse Spark model to work inside VS Code as a
coding agent: a chat panel that streams answers, reads and edits your files
with reviewable diffs, runs commands behind permission modes, delegates to
subagents you can watch and steer, remembers past conversations, and takes
dictation from your microphone. It runs on your Muse subscription through the
Muse Code CLI, or on a Meta Model API key, and never mixes the two.

## Highlights

- **Streaming chat with tools you can see.** Every read, edit, write and shell
  command is a row in the transcript: green when done, pulsing while running,
  red when refused. Edit rows show the diff, the path opens the file with the
  changed lines selected, **Click to expand** opens VS Code's diff editor, and
  any output opens in an editor tab with a click.
- **Permission modes, like Claude Code.** Manual, Edit automatically, Plan and
  Auto (Bypass behind a setting), switched from the mode button or
  `Shift+Tab`. Gated commands arrive as approval cards with the CLI's own
  choices; questions
