Beta Features and Early Access

Claude Code continues to evolve rapidly with experimental features and beta programs. This guide explains how to access, test, and provide feedback on cutting-edge capabilities before they reach general availability.

Understanding Feature Stages

Alpha

Internal or limited testing with significant changes expected. May have bugs or incomplete functionality.

Beta

Feature-complete but gathering feedback. Available to specific user groups or plans.

Preview

Near-final implementation. Broadly available but may have minor adjustments.

GA

Generally Available. Stable, supported, and recommended for production use.

Current Beta Features

Agent Teams Research Preview

Multi-agent collaboration where Claude Code spawns and coordinates teammate agents:

# Enable agent teams (research preview)
export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1

Features:

• Spawn multiple agent teammates that work in parallel
• TeammateIdle and TaskCompleted hooks for coordination (v2.1.33)
• Agents can have persistent memory with user, project, or local scope
• Restrict sub-agents via Task(agent_type) syntax in agent tools frontmatter

Caution

Agent teams is a research preview and is token-intensive. Requires setting the environment variable above to enable. Available since v2.1.32.

Fast Mode New in v2.1.36

Fast mode uses the same Claude Opus 4.6 model with faster output — no model switch.

# Toggle fast mode inside a session
/fast

Note

Fast mode is available for Opus 4.6. Toggle with /fast during a session. Fixed in v2.1.37 to be immediately available after /extra-usage.

GitHub Actions Integration Beta

Claude Code GitHub Actions enables AI-powered automation in your GitHub workflow:

.github/workflows/claude-review.yml

name: Claude Code Review
on: [pull_request, issue_comment]

jobs:
  claude-action:
    runs-on: ubuntu-latest
    steps:
      - uses: anthropics/claude-code-action@beta
        with:
          github-token: ${{ secrets.GITHUB_TOKEN }}
          anthropic-api-key: ${{ secrets.ANTHROPIC_API_KEY }}

Features:

• Respond to @claude mentions in issues and PRs
• Automatic code review and implementation
• Follows repository’s CLAUDE.md guidelines
• Creates branches, commits, and PRs automatically

Note

GitHub Actions integration is built on the Claude Code SDK, allowing custom automation workflows beyond standard features.

Native Binary Installation Alpha

An experimental installation method that provides platform-native binaries:

Install

# From existing Claude Code installation
claude install

# Fresh install via script
curl -fsSL claude.ai/install.sh | bash

Platforms

• macOS: Universal binary (Intel + Apple Silicon)
• Linux: x64 and ARM64 support
• Windows: Via WSL (native support in development)

Benefits

• Faster startup times
• Smaller memory footprint
• Better system integration
• No Node.js dependency

Caution

Native binary installation is currently in Alpha, not Beta. Expect potential issues and breaking changes.

Figma Dev Mode MCP Server Beta

Design-to-code integration through Model Context Protocol:

# Enable in Figma Desktop App
# Preferences → Dev Mode → Enable MCP Server

# Add to Claude Code
claude mcp add --transport sse figma-dev-mode http://127.0.0.1:3845/sse

Capabilities:

• Generate code from Figma designs
• Extract design tokens and variables
• Access Code Connect mappings
• Screenshot design regions

Caution

Requires Figma Dev Mode seat on Professional, Organization, or Enterprise plans.

Experimental Flags and Features

Environment Variables

CLAUDE_CODE_SHELL

Override automatic shell detection (v2.0.65)

export CLAUDE_CODE_SHELL=/bin/zsh

CLAUDE_CODE_PROXY_RESOLVES_HOSTS

Enable proxy DNS resolution (opt-in since v2.0.55)

export CLAUDE_CODE_PROXY_RESOLVES_HOSTS=true

CLAUDE_BASH_MAINTAIN_PROJECT_WORKING_DIR

Lock Bash tool to project root directory

export CLAUDE_BASH_MAINTAIN_PROJECT_WORKING_DIR=1

MCP_TIMEOUT

Adjust MCP server startup timeout (milliseconds)

export MCP_TIMEOUT=30000

Note

Thinking mode configuration has moved to /config as of v2.0.67. The DISABLE_INTERLEAVED_THINKING environment variable is deprecated.

Model Context Protocol (MCP) Servers

The MCP ecosystem includes many production-ready servers:

Development Tools

• Playwright/Puppeteer: Browser automation and testing
• Git: Version control operations
• GitHub/GitLab: Repository management
• PostgreSQL/MySQL: Database operations

Documentation & Knowledge

• Context7: Up-to-date library documentation
• Wikipedia: Reference information
• Google Search: Web search capabilities

Productivity

• Linear/Jira: Task management
• Slack: Team communication
• Google Drive: Document access
• Notion: Knowledge base integration

Tip

MCP servers are not experimental - they’re a core feature of Claude Code. New servers are regularly added by the community.

Accessing Features

Subscription Access

As of version 2.0.58, Claude Code is available to:

1. Claude Pro Plan: Full access to Claude Code with Opus 4.6 model (latest as of Feb 2026)
2. Claude Max Plan: Enhanced limits and priority Opus 4.6 access
3. Enterprise Plans: Custom configurations and support

Tip

Latest: Claude Opus 4.6 is now available (v2.1.32+). Both Pro and Max plans have access to the same Claude Code features. The main difference is usage limits.
