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.

Files

/agenthub:spawn — Launch Parallel Agents

Spawn N subagents that work on the same task in parallel, each in an isolated git worktree.

Usage

/agenthub:spawn                                    # Spawn agents for the latest session
/agenthub:spawn 20260317-143022                    # Spawn agents for a specific session
/agenthub:spawn --template optimizer               # Use optimizer template for dispatch prompts
/agenthub:spawn --template refactorer              # Use refactorer template

Templates

When --template <name> is provided, use the dispatch prompt from ../agenthub/references/agent-templates.md instead of the default prompt below. Available templates:

Template	Pattern	Use Case
`optimizer`	Edit → eval → keep/discard → repeat x10	Performance, latency, size reduction
`refactorer`	Restructure → test → iterate until green	Code quality, tech debt
`test-writer`	Write tests → measure coverage → repeat	Test coverage gaps
`bug-fixer`	Reproduce → diagnose → fix → verify	Bug fix with competing approaches
