Show HN: Multi-agent coding assistant with a sandboxed Rust execution engine (github.com) AI

Lula is an open-source, LangGraph-based multi-agent coding orchestrator that pairs a separate Rust “sandbox runner” for executing tool actions. The project emphasizes isolation and governance by running code in Firecracker MicroVMs or Linux namespaces (with a fallback mode) and requiring HMAC-signed approval gates at the tool-call level. It also includes features like a tripartite persistent memory model, checkpointing backends, and a VS Code extension/web UI for streaming run progress and reviewing diffs.
