## Description

If you've ever launched a chatbot only to find it sounding like a different person every three turns, you know how frustrating that is. It's hard to maintain a specific brand voice when the underlying logic gets messy. This MCP handles the heavy lifting of auditing those scripts. Instead of manually reading thousands of lines of dialogue to see if the bot is being too wordy or repeating itself, you can let your agent do the work. It checks if the bot's personality stays consistent and if the mix of questions and statements feels natural. You can spot where the bot starts sounding like a broken record or where its error messages feel unhelpful. It's a huge time saver for anyone who needs to ensure their conversational AI doesn't lose its way. You'll find this in the Vinkius catalog, where it fits right into a professional QA workflow. It turns a tedious manual review into a targeted diagnostic check. This means you can move faster from script to production without worrying about a bot that feels disjointed or robotic. It gives you the confidence that your bot will sound like it was written by a human who actually knows your brand. You can identify specific turns where the bot loses its cool or gets stuck in a loop, allowing you to fix the underlying prompt or logic before a customer ever sees it. It's about making sure your bot actually feels like your brand, every single time.

## Tools

### evaluate_fallback_quality
Checks if your I don't understand messages are actually helpful to the user. It ensures your bot provides clear next steps when it gets stuck.

### analyze_persona_alignment
Scans dialogue to see if the bot is sticking to its assigned character and tone. This helps you catch moments where the bot sounds too formal or overly casual.

### detect_phrase_repetition
Finds specific substrings that the bot keeps repeating to the user. It identifies those annoying loops that make for a frustrating user experience.

### calculate_structural_ratio
Measures the balance between questions and statements in the bot's responses. This helps you see if the bot is being too pushy or just talking at the user.

### calculate_turn_variance
Shows how much your bot's response lengths vary across a conversation. It highlights erratic behavior where the bot might be giving too much or too little info.

## Prompt Examples

**Prompt:** 
```
Does this bot sound like a professional concierge? Turns: ['Hello!', 'I can help with your booking.', 'Please tell me your name.']
```

**Response:** 
```
### Persona Alignment Audit

| Metric | Score | Notes |
| :--- | :--- | :--- |
| **Persona Alignment** | 0.92 | High adherence to professional tone. |
| **Tone** | Professional | Consistent use of polite verbs. |
| **Structural Balance** | 1.5 | Good mix of statements and requests. |

**Verdict:** The bot maintains a helpful, professional demeanor throughout these turns.
```

**Prompt:** 
```
Check if these responses are too repetitive: ['Please wait a moment.', 'Wait just a second.', 'Hold on, I am checking.']
```

**Response:** 
```
### Repetition Detection

**Repetition Found:**
* "Wait" / "Wait a moment"

**Analysis:**
While the phrasing varies slightly, the intent is repeated three times in a row. This can lead to user frustration if the bot stays in this loop for more than a few seconds.
```

**Prompt:** 
```
Are the response lengths consistent here? ['Hi.', 'I am very sorry that I was unable to find your account in our system.', 'Let me know if you need anything else.']
```

**Response:** 
```
### Turn Variance Report

**Variance Score:** 1.85

**Observations:**
* **Turn 1:** Very short (1 word)
* **Turn 2:** Long, detailed error message
* **Turn 3:** Medium length

**Recommendation:** The variance is high. Consider standardizing the length of your initial greetings to match the depth of your error responses.
```
