Spawn

Looking at this one, the source file appears to be empty or minimal, so I'll tell you what I can infer from the name. This appears to handle process spawning, letting Claude spin up child processes to run system commands or external tools. You'd reach for this when you need to execute shell commands, run scripts, or interact with command-line utilities during a task. The name suggests it's probably a wrapper around something like Node's child_process.spawn or Python's subprocess, making it available as a reusable skill. Without seeing the implementation details, I can't tell you about error handling or specific options, but process spawning is straightforward enough that the basics are likely covered.
