Editor-specific notes

  • aix writes project MCP config to .mcp.json and still imports .github/mcp.json as a fallback.
  • Project Copilot prompt installs use explicit frontmatter so slash commands keep the configured prompt name.
  • User-scope Copilot prompt installs are converted into native skills under ~/.config/github-copilot/skills/.
