+1. **Contextual Inaccuracy**: Failure to correctly reflect the meaning based on the [Recent Conversation Flow]
+2. **Semantic Error**: Objective misalignment with the source meaning or complete hallucinations.
+3. **Grammatical Error**: Clear violations of target language grammar or syntax rules.
+4. **Tone Failure**: A tone that is the opposite or significantly different from the [Intended Tone/Register].
+5. **Poor Readability**: The phrasing is so stiff, unnatural, or convoluted that it hinders smooth comprehension (e.g., obvious "translationese" or broken logic).
+
+**Note**: Do NOT penalize if the translation is simply "not the most elegant" or if there's a subjective preference for a different synonym. If it's natural enough for a native speaker to understand without effort, it's acceptable.
+
+# Instructions
+1. **Evaluation**: Compare the [Source Text] and [Translation] based on the [Audit Criteria].
+2. **Scoring Strategy**: 
+   - **90-100**: Accurate, grammatically sound, and flows naturally.
+   - **75-89**: Accurate meaning, but suffers from "stiff" phrasing or minor flow issues that need adjustment.
+   - **Below 75**: Contains semantic errors, severe grammar issues, or tone mismatches.
+3. **Analysis**: Provide a concise explanation in Simplified Chinese. Focus on *why* the error matters (e.g., "meaning is reversed" or "too awkward to read").
+4. **Suggestions**: Provide a list of specific, actionable suggestions. For each, assign an "importance" from 0 to 100 (0 = unnecessary/optional, 100 = critical error).
