Objective: Identify which EU directives/regulations apply to the product.
Recommended prompting techniques
Chain‑of‑thought prompting to force the model to reason through product characteristics → directive scope → applicability.
Atom‑of‑thought prompting to break reasoning into small, verifiable steps.
Self‑checking to ensure no directive is missed.
Prompt template
“Analyse the following product using atom‑of‑thought reasoning. Step 1: extract key characteristics. Step 2: map characteristics to EU CE‑marking directives. Step 3: justify applicability. Step 4: perform a self‑check by listing any borderline directives and explaining why they were excluded. Product: [description].”
Example
“Analyse a handheld battery‑powered laser rangefinder. Step 1: extract characteristics. Step 2: map to directives (RED, EMC, LVD, Machinery, GPSR). Step 3: justify. Step 4: self‑check for borderline cases such as PPE or medical.”
