Homebrew Bridge

Expose Mac Homebrew tools like brew, gh, and other /opt/homebrew/bin CLIs on a Linux OpenClaw gateway by installing explicit same-LAN SSH wrappers with optional Wake-on-LAN and OpenClaw config auto-discovery.

Use this skill when the real value is giving a Linux OpenClaw gateway access to a Mac node's Homebrew toolchain.

This skill is for /opt/homebrew/bin/<tool> wrappers such as:

• brew
• gh
• other Homebrew-installed CLIs you want to expose from a Mac node

Use This Skill For

• Linux gateways that should run Homebrew-backed tools through a Mac node
• wrapper-backed skills that depend on brew, gh, or another Homebrew CLI
• same-LAN Mac nodes that already hold the real Homebrew installs
• optional host auto-discovery from OpenClaw config when only one Mac owner is known

Do Not Use This Skill For

• tools that are inherently Mac-owned apps or permissioned CLIs like imsg or remindctl
• Linux-native tools that should be installed on Linux directly
• WAN-routed Macs or generic remote shell access

Requirements

• Linux gateway and owning Mac share the same trusted local network or VLAN
• Linux gateway can SSH to the owning Mac
• the requested tool exists at /opt/homebrew/bin/<tool> on that Mac
• the Mac stays awake during work windows or supports Wake-on-LAN

Workflow

1. Render A Tool Ownership Map

Run:

scripts/render-tool-map.sh /home/node/.openclaw/openclaw.json

This prints the inferred or fallback Mac owner for Homebrew-backed tools.

2. Install The Homebrew Pack

Example:

scripts/install-homebrew-pack.sh \
  --target-dir /home/node/.openclaw/bin \
  --tool brew \
  --tool gh \
  --tool claude \
  --default-host [e-mail] \
  --wake-map mac-node.local=AA:BB:CC:DD:EE:FF \
  --wake-wait 20 \
  --wake-retries 2

Host resolution order:

• explicit --map tool=user@host
• --default-host user@host
• the single discovered remoteHost in the OpenClaw config, if there is exactly one
• no repeated host questions when the OpenClaw config already resolves the owner

3. Verify The Pack

Run:

scripts/verify-homebrew-pack.sh --target-dir /home/node/.openclaw/bin

Design Contract

• Linux owns the stable wrapper paths
• the Mac owns the real /opt/homebrew/bin binaries
• public skills depend on wrapper paths, not Mac paths
• wrapper names stay explicit per tool

Files

• scripts/install-wrapper.sh: create one SSH wrapper for a remote binary
• scripts/install-homebrew-pack.sh: install a batch of Homebrew-backed wrappers
• scripts/verify-homebrew-pack.sh: verify the installed wrappers
• scripts/render-tool-map.sh: print inferred or fallback tool-to-host maps
• references/skill-readiness.md: publishability rules for Homebrew-backed wrappers
