Agent Runtime Parity
Use this skill when managing capabilities across multiple AI runtimes to prevent divergence, or when a configuration change, rule update, MCP addition, or credential routing must propagate uniformly to all active AI surfaces.
This skill ensures that team AI tools stay synchronized and that operational changes made in one runtime surface automatically propagate to others—eliminating manual copy-paste sync and the drift that follows.
Core Model
Treat your canonical source repository (e.g., <REPO_ROOT>/skills/, <REPO_ROOT>/rules/) as the single source of truth for cross-agent capabilities.
Active AI Surfaces
Define your active AI surfaces explicitly. Common examples:
