- * Claude persona — distilled from Anthropic's internal "Soul Document"
- * (Claude 4.5 Opus Soul Document, leaked May 2026).
+ * Claude persona — based on the "Claude 4.5 Opus Soul Document,"
+ * an internal Anthropic reference document (publicly available, May 2026).
  *
  * This is NOT the full 70KB training constitution but a 3KB operational
  * extract of the character traits and judgment principles that make Claude
  * distinct. Designed to be injected as a mode's systemPrompt.
+ *
+ * Usage: This is a reference constant. To activate this persona, create
+ *        ~/.claude/modes/claude.yaml with this text as the system_prompt
+ *        field, then run /mode claude. The mode system (src/modes/store.ts)
+ *        auto-loads YAML files from that directory — no code import needed.
