Restored Claude Code Source, Third-Party API Support

中文文档: README_CN.md

This repository is a restored Claude Code source tree reconstructed primarily from source maps and missing-module backfilling.

It is not the original upstream repository state. Some files were unrecoverable from source maps and have been replaced with compatibility shims or degraded implementations so the project can install and run again.

Third-Party LLM API Support

This fork has been modified to bypass Claude's preflight checks, enabling the use of third-party large language model APIs that are compatible with the Anthropic API format.

You can use any Anthropic-compatible API endpoint by setting the following environment variables:

ANTHROPIC_BASE_URL=https://api.minimaxi.com/anthropic \
ANTHROPIC_API_KEY=YOUR_API_KEY \
ANTHROPIC_MODEL=MiniMax-M2.7 \
bun run dev

Variable	Description
ANTHROPIC_BASE_URL	Base URL of the third-party Anthropic-compatible API
ANTHROPIC_API_KEY	Your API key for the third-party service
ANTHROPIC_MODEL	Model name to use (e.g. MiniMax-M2.7)

Note: The preflight authentication check that normally requires a valid Anthropic account has been removed. Any API key accepted by your chosen endpoint will work.

Current status

• The source tree is restorable and runnable in a local development workflow.
• bun install succeeds.
• bun run version succeeds.
• bun run dev now routes through the restored CLI bootstrap instead of the temporary dev-entry shim.
• bun run dev --help shows the full command tree from the restored CLI.
• A number of modules still contain restoration-time fallbacks, so behavior may differ from the original Claude Code implementation.

Restored so far

Recent restoration work has recovered several pieces beyond the initial source-map import:

• the default Bun scripts now start the real CLI bootstrap path
• bundled skill content for claude-api and verify has been rewritten from placeholder files into usable reference docs
• compatibility layers for Chrome MCP and Computer Use MCP now expose realistic tool catalogs and structured degraded-mode responses instead of empty stubs
• several explicit placeholder resources have been replaced with working fallback prompts for planning and permission-classifier flows

Remaining gaps are mostly private/native integrations where the original implementation was not recoverable from source maps, so those areas still rely on shims or reduced behavior.

Why this exists

Source maps do not contain a full original repository:

• type-only files are often missing
• build-time generated files may be absent
• private package wrappers and native bindings may not be recoverable
• dynamic imports and resource files are frequently incomplete

This repository fills those gaps enough to produce a usable, runnable restored workspace.

Run

Requirements:

• Bun 1.3.5 or newer
• Node.js 24 or newer

Install dependencies:

bun install

Run with a third-party API (recommended):

ANTHROPIC_BASE_URL=https://api.minimaxi.com/anthropic \
ANTHROPIC_API_KEY=YOUR_API_KEY \
ANTHROPIC_MODEL=MiniMax-M2.7 \
bun run dev

Or run the restored CLI directly:

bun run dev

Print the restored version:

bun run version
