Claude Code 2.1.88 Source Recovery

Skill by ara.so — Daily 2026 Skills collection.

This project contains the recovered TypeScript source code of @anthropic-ai/claude-code version 2.1.88, extracted from the accidentally published cli.js.map source map file (57MB). The restored codebase is ~700,000 lines of TypeScript organized into a clean directory structure.

How the Source Was Recovered

The cli.js.map file contained a sourcesContent field with all original source files. The recovery process:

// Conceptual recovery process
import * as fs from 'fs';

const sourceMap = JSON.parse(fs.readFileSync('cli.js.map', 'utf-8'));

// sourceMap.sources = array of original file paths
// sourceMap.sourcesContent = array of original file contents
