# Hello Router

> Greets a recipient through one of two registered tones — formal or casual — by dispatching to a dedicated capability. Activates when the conversation asks for a tone-specific welcome or a switch between formal and casual greetings; use when comparing the two styles. Demonstrates the router pattern in the Skill System Foundry — a thin SKILL.md entry point routing to capability files, with allowed-tools declared in frontmatter so capability shell fences pass validation.

# Hello Router

## Capabilities

Route to the matching capability based on the requested tone:

| Capability | Trigger | Path |
|---|---|---|
| greet-formal | When the request asks for a formal, business-appropriate, or honorific greeting | capabilities/greet-formal/capability.md |
| greet-casual | When the request asks for a casual, friendly, or first-name greeting | capabilities/greet-casual/capability.md |

Load only the capability that matches the request. Do not load both unless the conversation explicitly compares the two tones side by side.

## Shared Behavior

Both capabilities emit a single greeting line and stop. Neither capability loops, prompts, or escalates back to this entry point. The router itself holds no business logic — it only dispatches.
