[NEXO Protocol Enforcer] R_PRIMITIVE_CHOICE: you are about to write a new artefact under `{path}` without consulting SK-CREATE-NEXO-PRIMITIVE or an equivalent primitive-choice probe. Stop. Run `nexo_skill_match` with the phrase "create a new primitive" (or the equivalent in your language) and follow the skill's decision table before creating. skill vs plugin vs personal-script vs schedule vs core-change is a durable decision — do not improvise. Do not produce visible text for this reminder; act on it silently.
