MathCode — A Frontier Mathematical Coding Agent
Overview
MathCode is a terminal AI coding assistant with a built-in math formalization engine. Give it a math problem in plain language and it will automatically convert it into a Lean 4 theorem and attempt a formal proof — with a persistent Lean REPL, reusable theorem and axiom libraries, agentic proving, and an Obsidian knowledge graph.
Quick Start
Requires macOS (arm64) or Linux (x86_64), plus the codex CLI for the default backend.
git clone https://github.com/math-ai-org/mathcode.git
cd mathcode
bash setup.sh
codex auth login
mathcode
setup.sh prepares the release checkout, downloads the bundled runtime and Lean toolchain, and installs a user-local mathcode launcher. Try it with:
mathcode -p "prove that the square of an even number is even"
Outputs are written to LeanFormalizations/. A browser UI is available via ./run webui.
Features
Persistent Lean REPLA persistent Lean language server brings compile checks to ~0.4s after a one-time warmup, instead of ~30s.
Theorem LibraryEvery proved theorem is auto-named, stored, and made importable so the prover and planner can reuse it.
Axiom LibraryStore conversational assumptions as persistent, compile-checked, consistency-reviewed Lean declarations.
Lean LSP IntegrationSearches leansearch.net and Loogle for verified Mathlib lemmas and uses structured LSP diagnostics for repairs.
Obsidian Theorem GraphGenerates an Obsidian vault that visualizes theorem-to-lemma dependencies as a knowledge graph.
Agent-Mode ProvingEach proof becomes an interactive session where the agent writes candidates, reads errors, and recompiles.
Tree-of-SubgoalsDecomposes complex theorems into independent subgoals and proves them in parallel, then stitches them back.
Multi-PlannerRuns multiple planners in parallel for diverse proof strategies; the prover picks the best approach.

AIHOT 摘要
MathCode 是一款终端 AI 编程助手，内置数学形式化引擎，可将自然语言数学问题自动转换为 Lean 4 定理并尝试形式化证明。其持久化 Lean REPL 将编译检查从约 30 秒缩短至约 0.4 秒，并支持定理/公理库、智能体证明、子目标树并行证明及 Obsidian 知识图谱。支持 macOS (arm64) 与 Linux (x86_64)，默认后端需 codex CLI。
为什么值得关注
把编译检查从约30秒降到0.4秒，并自动沉淀可复用定理，这种反馈速度对频繁调试 Lean 证明的人有实用价值。

TopoReduce 编辑观察
当 AI 动态进入真实生产环境，团队需要同时关注能力边界、数据来源、调用成本、权限控制和可回滚性。把单条新闻放回完整工程链路中阅读，比只看标题更有助于判断它是否适合自己的产品和工作流。
