cross-platform-demo

name	cross-platform-demo
description	Run the shortest visible demo path across VICE and C64U.

Intent

Use this skill for quick greetings, smoke tests, and visible confirmation that one or more backends are responding.

Inputs

• Target backends: vice, c64u, or both.
• Optional message template when the default greeting is not sufficient.

Execution

0. Grouped MCP tools always require op. Do not call c64_program without it.
1. Execute c64_program with op: "cross_platform_greeting".
2. Pass platforms only when the user wants a subset of the configured backends.
3. Pass messageTemplate only when the user explicitly wants custom text.
4. On local machines with a graphical session, assume VICE should render in a real visible emulator window by default. Only expect Xvfb or other headless behavior in CI or when no framebuffer/display session exists.

Validation

1. Trust the workflow's structured verification first.
2. Summarize the reported text match results and screenshot paths.
3. Fall back to .github/skills/basic-program/SKILL.md only when the user needs custom program flow beyond a simple greeting, not merely because they want to see VICE render live.

Safety

• Warn if a running session may be overwritten by the demo.
• Do not add manual reset steps unless the workflow fails and the user confirms recovery actions.
