控制 what 你的 AI can see. LeanCTX (Lean Con 文本)是 the con 文本 intelligence layer 为 AI agents — one 本地 Rust binary decides what 它们 read, remembers what 它们 learn, guards what 它们 touch,、proves what 它们 save. 60–90% fewer 令牌 s asreceipt. 76 MCP 工具 s, 30+ agents, 本地优先.该项目在 GitHub 已获得 2,846 星标（278 分叉），代码活跃度高。主要编程语言为 Rust，采用 Apache-2.0 开源协议。主要标签：agentic-coding、ai、ai-agents、ai-coding、claude-code。
项目简介
控制 what 你的 AI can see. LeanCTX (Lean Con 文本)是 the con 文本 intelligence layer 为 AI agents — one 本地 Rust binary decides what 它们 read, remembers what 它们 learn, guards what 它们 touch,、proves what 它们 save. 60–90% fewer 令牌 s asreceipt. 76 MCP 工具 s, 30+ agents, 本地优先.
核心功能
- Longer useful coding sessions — less context waste = more room for actual code reasoning - Lower API costs — 60–90% fewer tokens on reads and shell output, cached re-reads cost ~13 tokens - No more "I already showed you this file" — session memory persists across chats - Works with your existing setup — one `lean-ctx setup` command, no config changes needed - Full visibility — see exactly where your context window budget goes
