Billion Context — Development skill for Claude Code

Development community

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.

A production-scale longitudinal study: 4.5 months, three hosts, 174,327 model calls, 18.76B cumulative input tokens (~24.7B across all hosts), zero window violations on 204,800-token models, marathon sessions of 8,584–12,049 calls.

npm install -g billion-context

`billion-context` sits between **any** agent and its model API, rewriting Anthropic/OpenAI streams with [acp-kernel](https://github.com/ranxianglei/acp-kernel) compression. The model decides **when** and **what** to compress into high-fidelity summaries — not a hard truncation limit.
