What This Repository Is

my-claude-code is a personal fork of Anthropic's Claude Code CLI, maintained as a public build workspace.

This fork makes three practical changes over upstream:

• telemetry-related behavior is removed or stubbed where possible
• prompt-layer restrictions added by the CLI wrapper are reduced
• build-time experimental feature flags are exposed for local builds and testing

Quick Start

Option 1: Clone and build locally

git clone https://github.com/Icarus603/my-claude-code.git
cd my-claude-code
bun install
bun run build
./dist/cli.js

Option 2: One-line installer

curl -fsSL https://raw.githubusercontent.com/Icarus603/my-claude-code/main/install.sh | bash

The installer checks your system, installs Bun if needed, clones the repo, builds dist/cli.js, and symlinks my-claude-code into ~/.local/bin.

Uninstall

To completely remove my-claude-code from your system:

# Remove the binary symlink
rm ~/.local/bin/my-claude-code

# Remove the installation directory
rm -rf ~/my-claude-code

# Remove configuration and cache (optional)
rm -rf ~/.my-claude-code

Authentication and Providers

This repo supports multiple providers, but they do not all authenticate the same way.

Anthropic

Use Anthropic directly with either:

• ANTHROPIC_API_KEY
• /login for Anthropic OAuth

export ANTHROPIC_API_KEY="..."
./dist/cli.js

OpenAI Codex

Codex authenticates via OpenAI OAuth through the CLI:

./dist/cli.js

Inside the CLI, run /login and choose the Codex login flow.

After a successful Codex login, CLAUDE_CODE_USE_OPENAI=1 is persisted in your user config automatically, so new terminal sessions will continue using OpenAI Codex without a manual export.

Supported model examples:

AWS Bedrock

Bedrock does not use /login. It uses AWS credentials plus provider flags.

export CLAUDE_CODE_USE_BEDROCK=1
export AWS_REGION="us-east-1"
./dist/cli.js

Google Vertex AI

Vertex does not use /login. It uses Google Cloud credentials.

gcloud auth application-default login
export CLAUDE_CODE_USE_VERTEX=1
./dist/cli.js

Anthropic Foundry

Foundry does not use /login. It uses explicit environment configuration.

export CLAUDE_CODE_USE_FOUNDRY=1
export ANTHROPIC_FOUNDRY_API_KEY="..."
./dist/cli.js

Provider Summary

Build and Run

Requirements

• Bun >= 1.3.11
• macOS or Linux
• valid credentials for whichever provider you plan to use

Install Bun if needed:

curl -fsSL https://bun.sh/install | bash

Standard build

bun install
bun run build
./dist/cli.js

Build output

Common usage

# interactive mode
./dist/cli.js

# one-shot prompt
./dist/cli.js -p "what files are in this directory?"

# choose a model explicitly
./dist/cli.js --model claude-opus-4-6

# switch to Codex backend
CLAUDE_CODE_USE_OPENAI=1 ./dist/cli.js

Selected environment variables

Config isolation

This fork defaults CLAUDE_CONFIG_DIR to ~/.my-claude-code so its settings, auth tokens, teammate models, and MCP configs are fully separate from an official Claude Code installation in ~/.claude.

To share config with the official installation:

export CLAUDE_CONFIG_DIR="$HOME/.claude"
./dist/cli.js

Feature Flags and Supporting Docs

• FEATURES.md: technical audit of compile-time feature flags in this snapshot
• AGENTS.md: Codex-oriented repo guidance for coding agents
• CLAUDE.md: Claude-oriented repo guidance for coding agents
• ARCHITECTURE.md: deep-dive into codebase design and architecture

The default build already includes this repo's current working feature bundle:

bun run build
./dist/cli.js

To enable specific flags manually:

bun run ./scripts/build.ts --feature=ULTRAPLAN --feature=ULTRATHINK
