Apex Arc

Apex Arc is a terminal-native AI coding assistant. It can read and write code, run commands, manage Git, and use a persistent memory system to keep a deep understanding of your project across sessions while continuously improving itself.

Quick Start

For full Windows, macOS, and Linux setup instructions, see the Apex Arc Installation Guide.

# Install via npm
npm install -g @pyintel/arc

# Run
apex-arc

The global install links both commands:

apex-arc
arc

If you install without -g, npm installs Apex Arc into the current directory's node_modules and does not add the commands to your shell PATH. Run a local install with:

npx apex-arc

Older published versions may show an npm approve-scripts warning for the package postinstall script. Current releases do not require that script; if you see the warning on an older version, reinstall the latest global package:

npm install -g @pyintel/arc@latest

Verify the install:

arc --version
arc --help

The first launch guides you through configuration automatically. Supported options:

• Import from Claude Code — migrate existing authentication in one step
• Custom Provider — add any OpenAI-compatible API in the TUI

Core Features

• Multiple Agents — build (default), plan (read-only analysis), compose (specs-driven orchestration); press Tab to switch
• Persistent Memory — cross-session project knowledge, checkpoints, and task progress powered by SQLite FTS5
• Intelligent Context Management — automatic checkpoints, context reconstruction, and budgeted injection to stay within model limits
• Task Tracking — tree-shaped task system integrated with the checkpoint system
• Subagent System — parallel subagents with lifecycle tracking, cancellation, and background execution
• Goal / Stop Condition — judge model prevents premature stops during autonomous work
• Compose Mode — structured workflow for specs-driven development with built-in skills
• Dream & Distill — extract knowledge into memory (/dream) and discover reusable workflows (/distill)

For detailed documentation, configuration options, and troubleshooting, see the GitHub repository.
