# Runtime Compatibility

The `impeccable-*` references are portable design and review playbooks consolidated from the source package.

Do not assume the original Impeccable runtime is installed. In particular:

- do not execute references to `.impeccable`, vendor hooks, agent profiles, live-edit servers, or omitted `scripts/` paths;
- use `mcp-browser-automation` for browser inspection and validation;
- use repository-native patching and review workflows for code changes;
- treat platform-native references as design guidance unless the target is actually a native application;
- if a playbook depends on an unavailable capability, preserve its intent and use the nearest installed MCP skill.
