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.
