Lightweight single-writer concurrency

Engine-agnostic multi-agent workflow orchestration with journaled replay/resume

A lightweight MQTT 3.1.1 broker implemented in MoonBit.

High-performance, pure MoonBit Immediate-Mode GUI library for WebAssembly, Canvas, and Games.

LLM Agent framework with hexagonal (ports-and-adapters) architecture. Defines 9 traits + Agent loop. Depends on moonbitlang/async.

Image / video labeling backend for the MoonbitLabeler app: 21 async ops over @fs/@json for folder browsing, image IO, label IO, schema normalization (parse/serialize round-trip), class management, and VOC/YOLO export. The op_handlers are pure async MoonBit functions and can be wired into any IPC layer (Proton/CEF, stdio JSON-RPC, HTTP, WASM, custom bridge). Includes a `dispatch_op(op, payload) -> Json raise` entry point in 0.2.0+ for embedding outside the CEF runtime.

A pluggable CSS preprocessor compile facade: a single function turns SCSS / LESS / CSS source (or file) into CSS, routing to swappable backend engines.

Deterministic repository change-policy evaluation and review planning for MoonBit

Portable weaving draft simulation, liftplan compilation and periodic float analysis

Conservative JSON syntax repair with replayable edits and explicit refusal boundaries.

Deterministic record-and-replay (cassette) for LLM interactions: write offline, reproducible, drift-detecting regression tests for LLM applications without API keys or network.

Numeric kernel of atools: FFT, STFT codec and phase reconstruction, compiled to WASM for direct browser use
