rpi-setup skill points to dead @codelayer/linear-cli; the real package is macOS-only

[tylerxia8]

The rpi-setup-humanlayer skill (Step 2 of the prerequisite checks) instructs:

npm install -g @codelayer/linear-cli

…but that package returns 404 on npm (so does @codelayer/cli).

The actual package is @humanlayer/linear-cli (v0.6.0) — but it ships only a macOS arm64 Mach-O binary as dist/linear, with no os/cpu guard and no postinstall step. So on Windows/Linux it "installs" fine but fails at runtime:

cannot execute binary file: Exec format error

and the skill's which linear check can never pass.

Impact

Non-Mac users can't complete the Linear prerequisite at all.

Suggested fixes

1. Update the skill's install command to @humanlayer/linear-cli.
2. Publish Windows/Linux binaries, or document Linear's official MCP server (https://mcp.linear.app/mcp) as the cross-platform path for the Linear integration.

Environment

Windows 11, Node 24, @humanlayer/linear-cli@0.6.0.
