## models and pricing

Muse Code runs Meta’s Muse Spark model family, co-trained with the agent; other providers and local models are not supported. Subscriptions run from Everyday at $5/mo to Maximum at $200/mo, with usage multipliers at each tier, and pay-per-token billing through a Meta Model API key is also available.

## what it’s good at

Muse Code fans large jobs out to persistent sub-agents in isolated git worktrees, and its headless mode suits scripts and CI pipelines. A TypeScript SDK and cross-session messaging support building on top of it, and it runs on macOS, Linux, and Windows.

## Muse Code in crystl

Muse Code runs in a crystl shard with its own model selection and activity visibility, and a prompt can be handed to it at launch for one-shot worker runs. Crystl recognises the agent and tracks its activity, but the deeper surfaces are still unwired: its tool calls raise no approval cards, its sessions have no transcript crystl can read, and no resume command is documented for it.

A spawned Muse Code worker reports done when its process exits rather than on a turn-end hook.

The profile describes what crystl has tested; it never supplies a command, hook script, or launch setting. Those remain local to the Crystl installation.
