NERV-CODE is a NERV/MAGI-themed restoration of the Claude Code CLI (v2.1.88), reconstructed from the public npm package's sourcemap. The full TypeScript source has been extracted, themed with Neon Genesis Evangelion aesthetics, and can be compiled and run as a fully functional AI coding assistant.
This is a research & fan project — all functionality comes from the original Claude Code; we only added the NERV paint job.
In the spirit of open source community etiquette, we gratefully acknowledge:
This project stands on the shoulders of giants:
- zxdxjtu/claude-code-sourcemap — Original sourcemap extraction and source restoration methodology
- ChinaSiro/claude-code-sourcemap — Build system, documentation, and community contributions
- Claude Code source code is copyright Anthropic, PBC. This project is reconstructed from publicly available npm packages for research and educational purposes only. Not for commercial use.
- Neon Genesis Evangelion (新世紀エヴァンゲリオン) is created by Hideaki Anno / Studio Gainax / khara, Inc. All NERV/MAGI/EVA references in this project are a fan tribute for entertainment purposes only (新世纪福音战士致敬仅供娱乐). No affiliation with or endorsement by the rights holders.
- Node.js >= 18
- Bun >= 1.0 (build only)
- An Anthropic API key (for actual Claude conversations)
bash install.shThe script will install dependencies, restore internal SDKs, build the project, and create a nerv command in ~/.local/bin/.
# 1. Install dependencies (推荐 bun，项目构建脚本依赖 bun)
bun install
# 如果使用 npm，必须加 --legacy-peer-deps：
# npm install --legacy-peer-deps
# 原因：项目使用 react@19.3.0-canary，npm 的 semver 严格模式
# 认为 canary 预发布版本不满足 react-compiler-runtime 的
# peerDependency "^19"，会报依赖冲突。bun 无此问题。
# 2. Restore Anthropic internal SDKs (from sourcemap)
cp -r node_modules_sourcemap/@anthropic-ai/bedrock-sdk node_modules/@anthropic-ai/
cp -r node_modules_sourcemap/@anthropic-ai/vertex-sdk node_modules/@anthropic-ai/
cp -r node_modules_sourcemap/@anthropic-ai/foundry-sdk node_modules/@anthropic-ai/
# 3. Build
bun run build.ts# Version check
node dist/cli.js --version # → 2.1.88 (NERV CODE)
# Help
node dist/cli.js --help
# Interactive mode (must be in a real terminal — TTY required)
node dist/cli.js
# Pipe mode (requires API key)
ANTHROPIC_API_KEY=sk-ant-xxx node dist/cli.js -p 'hello'Note: Interactive mode requires a real terminal (Terminal.app, iTerm2, etc.). IDE integrated terminals may not work due to TTY detection. Set
CLAUDE_CODE_FORCE_INTERACTIVE=1to force interactive mode.
