computer-use input tools broken on macOS ARM (M3) - missing native module

Description

Computer-use MCP input tools (left_click, type, key, double_click, computer_batch, etc.) all fail on macOS ARM (Apple M3) with:

Cannot find module '/home/runner/code/tmp/claude-cli-external-build-2216/node_modules/@ant/computer-use-input/prebuilds/computer-use-input.node'

The screenshot tool works fine. Only input tools are affected.

Environment

• Claude Code version: 2.1.100 (also broken on 2.1.89)
• Platform: macOS Sequoia 15.7.4 (Darwin 24.6.0)
• Chip: Apple M3 Pro (ARM64)
• Install method: npm global (/opt/homebrew/lib/node_modules/@anthropic-ai/claude-code/)

Root Cause

The error path /home/runner/code/tmp/claude-cli-external-build-2216/ is a Linux CI build path, not a macOS path. The native prebuilt binary computer-use-input.node appears to only be compiled for Linux and is not included for darwin-arm64.

Steps to Reproduce

1. Install Claude Code on macOS ARM (M3/M4)
2. Use computer-use MCP: request_access, then screenshot (works), then left_click (fails)
3. All input tools fail with the same missing module error

Expected Behavior

Input tools should work on macOS ARM, same as screenshot does.

Workaround

Used Python's Quartz framework (CGEventCreateMouseEvent, CGEventCreateKeyboardEvent) to simulate mouse/keyboard input as a workaround, but this is very clunky.
