Area

packages/contracts or packages/shared

Problem or use case

Meta has released Muse Code, their own AI agent coding terminal harness alongside their newest Muse Spark 1.2 model. Currently T3 Code does not support Muse Code as a coding harness.

Proposed solution

Add Muse Code as a supported option for T3 Code.

Why this matters

If you pick the Muse Spark 1.2 contributor option where they can train on your data, this is the best value model available.

Smallest useful scope

Muse Code as a coding agent.
