Cyrene Agent is an open-source Windows desktop assistant featuring a Live2D interface based on Cyrene from Honkai: Star Rail. Powered by an Electron and TypeScript stack, it combines roleplay interactions, multi-tier persistent memory, voice input/output, and sandboxed autonomous tool dispatch across four targeted operating modes.

Technical Overview of Cyrene Agent

Engineered on Electron 43 and Node.js 24 LTS, the application executes tasks through an autonomous Agent loop called CyreneHarness that manages tool calls, state checkpoints, and non-idempotent side effects. The software requires installation via an installer or source build, with key screen capture components compiled into native Rust binaries to avoid runtime overhead. Local semantic processing relies on an optional onnx-quantized BGE-M3 model, keeping embeddings on your own machine.

Core Features of Cyrene Agent

  • CyreneHarness loop manages execution safety through permission checks, crash-resilient checkpoints, mid-loop context compaction, and side-effect rollback protection.
  • Hierarchical memory tiers (L0/L1/L2) store persistent user profiles, recent contexts, and long-term notes locally via a DMAE lifecycle algorithm.
  • Integrated code workspace supports restricted directory execution, Git operations, and LSP queries across 13 programming languages.
  • Obsidian Vault integration links notes, learning materials, and practice schedules into an offline RAG pipeline.
  • Extensible plugin SDK lets users install audited community tools, window modules, and MCP servers without proprietary vendor lock-in.

System Compatibility & Updates

Cyrene Agent supports 64-bit Windows 10 and Windows 11 (x64), requiring Node.js 24 LTS and MSVC tools for compilation. Recent updates deployed DMAE v5.1 item lifecycle scheduling, alongside native OneBot 11/NapCat multi-platform channel support and AG-UI decoupling.

Why Choose Cyrene Agent?

Cyrene Agent gives users complete local ownership over their assistant's memory, tools, and code interactions without background surveillance or forced telemetry. Its MIT-licensed architecture provides verifiable task sandboxing, combining desktop companion visuals with production-grade task orchestration.
