Rationale

Dimension Rationale
Reliability First-party vendor guidance — Anthropic knows Claude's behavior best.
Relevance Medium — guidance on positive vs negative framing, but from Claude's vendor (may not generalize to all LLMs).
Bias flags COI: Anthropic has commercial interest in users succeeding with their product. Selective reporting: may not surface all failure modes.
