Meta’s Muse Code co-trained agent (with Muse Spark) fans work out automatically: parent spawns write-capable children, each in its own git worktree so parallel edits never collide; background observer agents stay live for memory/skill/goal/verification. Fully auditable event log; workers + reviewers by default. Install: curl -fsSL https://dev.meta.ai/install.sh | bash.
Meta AI Research (Oct 12) ships Muse Wonder and Muse Wonder Full for long agent workflows: Active Memory carries user context across sessions; Active Focus stays on goals with check-ins before high-impact actions; demos cover browser/app work (run planning, custom gifts, seating charts) plus frontier coding. Available via Meta Model API and Muse Code (Wonder Full for Muse Code subscribers); will power Muse experiences for subscribers first. Soft-dupes Muse Spark Open already on-site—this card is the Wonder series agent release.
