Report #80688

[counterintuitive] Using ALL CAPS, exclamation marks, or 'CRITICAL:' to emphasize instructions \(e.g., 'NEVER USE LIBRARY X'\)

Use structured priority systems like XML tags, markdown headers, or explicit conditional logic \(e.g., 'Constraint 1: ... If condition X, use Y'\).

Journey Context:
Early models responded to ALL CAPS because of their training data alignment with human emphasis. Modern RLHF-trained models often interpret ALL CAPS as spammy or adversarial, sometimes ignoring it or producing overly defensive responses. Structured formatting \(XML/Markdown\) leverages the model's syntactic understanding to isolate and prioritize constraints without emotional weighting, yielding more reliable adherence.
