A stable identity for a persona prompt, reusing LLMR's content-hash convention. Two agents with the same brief and name hash identically; any wording change flips the hash.
Arguments
- persona
Character scalar (the persona brief) or a
persona_frame().- name
Optional agent name folded into the hash (two agents with the same brief but different display names are arguably different personas).
Value
A 64-character SHA-256 hex string (see LLMR::llm_hash()).
