Use the Liney CLI (`liney`) to inspect or control a running Liney terminal workspace and the agent sessions it hosts. Liney runs several coding agents in parallel, each in its own pane/tab/worktree, so reach for this whenever the user wants to act on a pane other than the current one — check on, coordinate, read from, or send text/keys to another pane, tab, worktree, or sibling agent. Covers framings that never say "liney": "what is the agent in my other window doing", "are my side-by-side agents still working or waiting?", "tell the agent in my left split to rerun the tests", "read the build pane's output", "which of my agents is blocked?". Not for ordinary editing or building inside the Liney source repo, and not for questions about Liney's settings or keybindings — only when the task is to actually drive panes in the live app.

Use this skill when the user wants to create, run, stop, clone, push/pull, SSH into, or otherwise manage VM4A virtual machines via the `vm4a` CLI. Triggers include any mention of VM4A + "VM", the commands `vm4a create`, `vm4a run`, `vm4a pull`, `vm4a ssh`, "linux VM on mac", "macOS VM via CLI", or requests to automate VM lifecycle (CI, scripting, batch clones). Both Linux and macOS guests are supported; macOS first-boot needs one manual Setup Assistant click-through per fresh IPSW (Apple doesn't expose a scriptable skip). Do NOT use this skill for: the SwiftUI app itself (open Xcode instead), non-VM4A VM tools (UTM/VirtualBuddy/tart have their own CLIs), or questions about the Virtualization.framework itself.
