Plugin插件 Native原生 ⭐ 496 NOASSERTION Sessions & Context会话与上下文

基本稳定可用 A context-compression plugin for small context windows (a 100K context is enough), token savings (5x fewer tokens), and month-long single sessions (billions of tokens).上下文压缩插件,兼顾小窗口(100k上下文足矣)省token(省5倍token)和超长会话(数月级别几十亿token单会话)。billion-context is all you need

Project Overview项目介绍

billion-context is a universal context compression proxy designed for long-lived AI coding agents. To install it globally on your system, you can run the single command npm install -g billion-context from any terminal with a supported version of Node.js installed. It works with any AI coding agent that supports setting a custom base URL for model APIs, including popular options like Claude Code, Codex, Cursor, Aider, and DSH. It requires no per-agent custom adapter code to get up and running, and supports both OpenAI and Anthropic request formats out of the box for most mainstream model endpoints.

This tool solves the common problem of context window overflow during long multi-day coding sessions, which can degrade model performance or end an active working session entirely. It uses model-driven incremental hierarchical compression to fold older conversation history into high-fidelity layered summaries, letting you run billions of cumulative tokens through a standard 200k-token context window without violations. It is built for developers who work on large long-term coding projects with AI agents, and want to reduce token costs while keeping uninterrupted sessions active over multiple days or even weeks.

billion-context is released under the permissive MIT open-source license, and its accompanying research paper is also hosted in the repository under the same license. It is currently marked as early-stage software, so users should expect minor rough edges and occasional unexpected behavior as active development continues. The project also hosts an open QQ group for community discussion, updates, and user support for all related compression tools. Windows users specifically need to add the default session storage directory to their antivirus exclusion list to prevent file locking errors that block session state saves.

billion-context 是一款通用的 AI 编码代理上下文压缩代理服务,可在任意支持自定义模型基础 URL 的编码代理与 OpenAI/Anthropic 格式的模型 API 之间工作,通过增量分层压缩技术压缩历史对话,支持 Claude Code、Codex、Cursor、DSH 等几乎所有主流 AI 编码代理,无需为每个代理编写专用适配代码。

用户只需将本地运行的代理地址填入编码代理的模型 base URL 配置即可启用,它会自动解析传入请求,运行压缩算法,注入上下文管理工具后转发请求到真实模型 API,适合需要进行长时间、多轮次编码开发,希望避免上下文窗口溢出、降低 token 成本的开发人员使用。

本项目采用 MIT 许可证开源,可通过 npm install -g billion-context 命令全局安装,目前处于早期开发阶段,存在部分粗糙边界问题,Windows 用户需要将会话存储目录加入杀毒软件排除列表,避免写入权限错误导致会话状态保存失败。

  • Conflicts with installed plugins: command names, skill / tool names, ports, duplicate MCP registration与已装插件是否冲突:命令名、skill / tool 重名、端口占用、重复 MCP 注册

Security安全性

  • Repo matches the facts registered here; archived or abandoned?仓库是否与页面登记一致,是否归档或长期停更
