How do I replicate the 'Explanatory' mode now?

You can now install the 'explanatory-output-style' plugin from the marketplace or use SessionStart hooks to add educational context to your session.

How does this differ from using a CLAUDE.md file?

While CLAUDE.md provides project-specific context, Output Styles (now Plugins) allow for deeper modification of Claude's core behavioral logic and interaction style.

What happened to Claude Code Output Styles?

Output styles were deprecated on November 5, 2025, and have been automatically converted into the plugin system for better flexibility and power.

What is the best alternative for custom system prompts?

Plugins are the primary replacement, but you can also use Subagents for task-specific assistants or '--append-system-prompt' for session-specific instructions.
