TL;DR
- Muse Code uses an append-only event log to ensure replay-exact session recovery after crashes.
- Async background subagents remain active across tasks, avoiding redundant context collection.
- Default slash commands include /plan, /grill for stress-testing, and /goal for long-running targets.
Key facts
- Optimization Horizon
- 1,000+ tool calls (up to 24 hours)
- Target GPU Architecture
- NVIDIA Hopper (Triton KDA / MLA kernels)
- Installation Method
- curl -fsSL https://dev.meta.ai/install.sh | bash
Terminal-First Agentic Architecture
Muse Code operates as a CLI application powered by Meta's Muse Spark 1.2 model. The agent uses a local event log that records every model call, tool execution, edit, and user approval in an append-only format, ensuring replay-exact session restoration after interruptions.
Slash Commands and Workflow Orchestration
Built-in workflow triggers include:
/plan: Generates approval-gated task plans before code execution./grill: Stress-tests generated plans against edge cases and failure modes./goal: Directs persistent subagents toward targeted objective completion.
Autonomous Triton Kernel Optimization
During evaluations on NVIDIA Hopper GPUs, Muse Spark 1.2 continuously generated, compiled, and benchmarked Triton GPU kernels over 1,000+ tool iterations spanning up to 24 hours. The model implemented chunk-parallel preparation kernels and sequential inter-chunk scans for KDA and MLA algorithms without external library imports.

curl -fsSL https://dev.meta.ai/install.sh | bashWhen to use
- Running multi-step coding workflows across large repositories in the terminal.
- Iteratively writing and benchmarking low-level GPU kernels in Triton.
- Long-running tasks that require persistent subagent coordination and crash recovery.
When NOT to use
- Quick single-prompt edits that do not justify background agent execution.
- Environments requiring verification without Meta account setup.
What to do today
- Install Muse Code via dev.meta.ai install script.
- Test /plan and /grill commands on a sub-module before committing large context runs.
