-2. Tone & Register: 
+2. Personalization & Tone: Ensure all grammatical agreements and self-referential terms reflect speaker's gender. Faithfully replicate the intended tone, maintaining the formality, emotional nuance, and unique style of the source text without neutralizing it.
-   - If translating for 'Me', strictly use the tone: {MY_TONE}.
-   - If translating for 'Partner', auto-detect and preserve their original tone/emotion.
 3. Natural Flow: Keep the translation concise and natural for a chat environment. Avoid "translationese".
 4. Strictly avoid over-translation: Do not add extra information not present in the source text.
 5. Output ONLY the translated text, no explanations.`;

-1. **Contextual Accuracy**: Do pronouns (it, that, etc.) correctly point to objects/topics mentioned in the [Conversation History]?
+- Speaker: {SENDER_NAME}
-2. **Relational Tone**: Does the translation match the [Target Tone]? (e.g., if set to 'Polite', is it too casual?)
+- Source Language: {FROM_LANG}
-3. **Consistency**: Are names, terms, or previously established facts handled consistently?
+- Target Language: {TO_LANG}
-4. **Naturalness**: Is it concise and fit for an IM (Instant Messaging) environment?
+- Intended Tone/Register: {TARGET_TONE}
+
+# Audit Criteria
+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. Analyze the [Source Text] and [Current Translation] against the history.
+1. **Evaluation**: Compare the [Source Text] and [Translation] based on the [Audit Criteria].
-2. Scoring: 0-100.
+2. **Scoring Strategy**: 
-3. Suggestions: Provide actionable improvements. 
+   - **90-100**: Accurate, grammatically sound, and flows naturally.
-4. **Severity Level**: For each suggestion, assign an "importance" score (0-100).
+   - **75-89**: Accurate meaning, but suffers from "stiff" phrasing or minor flow issues that need adjustment.
-   - **80-100 (Critical)**: Misunderstanding meaning, wrong pronoun reference, or offensive tone.
+   - **Below 75**: Contains semantic errors, severe grammar issues, or tone mismatches.
-   - **40-79 (Moderate)**: Unnatural phrasing, minor tone mismatch.
+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").
-   - **0-39 (Minor)**: Polishing, stylistic preferences.
+4. **Suggestions**: Provide a list of specific, actionable suggestions. For each, assign an "importance" from 0 to 100 (0 = unnecessary/optional, 100 = critical error).
