Finding a typo in Fourth Wing using AI

<chapter_text>
{{ chapterText }}
</chapter_text>
You are an AI assistant specializing in narrative analysis and character linguistics. Your task is to analyze the <chapter_text> above to identify and extract all unique identifiers (appellations) that characters use to refer to one another. Follow these instructions carefully:
Your goal is to create a structured list of appellations in the format (Source, Appellation, Target). Analyze the <chapter_text> above and follow these steps:
1. Analyze the Text:
   - Read the chapter text thoroughly, paying close attention to dialogue, narration, and internal monologue.
   - Your goal is to find how one entity refers to another using a specific name or identifier.
   - Focus on identifiers such as:
     - Diminutives (e.g., "Sam" for Samuel)
     - Pet names or nicknames (e.g., "sis", "buddy", "love")
     - Formal titles used as unique identifiers (e.g., "the Captain", "Professor")
     - Epithets or descriptive names (e.g., "Wise One", "the tall stranger")
     - Any other name-like identifier that singles out a specific character (e.g., "Elara", "Mr. Blackwood").
2. Identify Appellations:
   For each unique identifier you find, identify the three key components:
   - Source: The character that _uses_ the identifier (the speaker or thinker). You will record their name as it appears in the text.
   - Target: The character that is _being referred to_ by the identifier. You will record their name as it appears in the text.
   - Appellation: The description of the identifier itself (see step 3).
3. Define the Appellation:
   The appellation consists of three parts: a phrase, a type, and a context.
   Phrase (`phrase`): The literal, exact string from the text that is used as the identifier (e.g., "Sam", "the Captain", "Wise One").
   Type (`type`): Choose the most fitting type that best describes the identifier. Use uppercase format. Here are the valid types:
   - DIMINUTIVE: A shortened or familiar form of a proper name (e.g., "Sam" for Samuel, "Liz" for Elizabeth).
   - PET_NAME: An informal, often affectionate, name not based on the proper name (e.g., "sis", "buddy", "darling").
   - FORMAL_TITLE: A rank, profession, or honorific used as an identifier (e.g., "the Captain", "Professor", "My Lord").
   - EPITHET: A descriptive phrase or adjective-based name (e.g., "the Wise One", "the tall stranger", "Man of Steel").
   - GIVEN_NAME: The character's standard first name, last name, or full name (e.g., "Elara", "Blackwood", "Marcus Blackwood").
   Context (`context`): Write a concise, one-sentence description of the usage. This should explain the nature of its use (e.g., "Used affectionately," "Used as a formal address," "Used when angry") and note its frequency if apparent.
4. Output Format:
   Your final output must be a single JSON object. Do not include any text or explanations outside of this block. For each unique appellation you identify, create an object following this exact structure:
```json
{
  "appellations": [
    {
      "sourceCharacterName": "[character name as it appears in the text]",
      "appellation": {
        "phrase": "[Literal phrase from text, e.g., 'Sam']",
        "type": "[APPELLATION_TYPE]",
        "context": "[Concise description of its usage, tone, and frequency.]"
      },
      "targetCharacterName": "[character name as it appears in the text]"
    }
  ]
}
```
Example:
```json
{
  "appellations": [
    {
      "sourceCharacterName": "Lena",
      "appellation": {
        "phrase": "Marcus",
        "type": "GIVEN_NAME",
        "context": "Used as a standard, familiar address during conversation."
      },
      "targetCharacterName": "Marcus"
    },
    {
      "sourceCharacterName": "Marcus",
      "appellation": {
        "phrase": "Lena",
        "type": "DIMINUTIVE",
        "context": "An affectionate diminutive used frequently in private, e.g., \"Lena, you can't mean it!\""
      },
      "targetCharacterName": "Lena"
    },
    {
      "sourceCharacterName": "Kaelen",
      "appellation": {
        "phrase": "the old man",
        "type": "EPITHET",
        "context": "Used in internal monologue to dismissively refer to the Elder."
      },
      "targetCharacterName": "Elder"
    },
    {
      "sourceCharacterName": "Guard",
      "appellation": {
        "phrase": "Captain",
        "type": "FORMAL_TITLE",
        "context": "Used as a formal, respectful address of rank."
      },
      "targetCharacterName": "Kaelen"
    }
  ]
}
```
Remember:
- The `phrase` value MUST be the literal, case-sensitive string found in the text.
- Aggregate multiple uses of the _exact same_ (Source name, Target name, Phrase) combination. Your `context` entry should summarize the overall usage, tone, and frequency (e.g., "Used regularly, always affectionately," or "A common, neutral identifier."). Do not create duplicate entries.
- Adhere strictly to the provided JSON format for your output.
Now, analyze the chapter text and produce your list of appellations following these instructions. Your final output should contain only the JSON object with appellations.

import { readFileSync } from "fs";
import { join } from "path";
import Anthropic from "@anthropic-ai/sdk";
import { Template } from "@huggingface/jinja";
const __dirname = new URL(".", import.meta.url).pathname;
const chapterText = readFileSync(join(__dirname, "chapter-content.txt"), "utf-8");
const templateSource = readFileSync(join(__dirname, "prompt-v1.jinja"), "utf-8");
const template = new Template(templateSource);
const prompt = template.render({ chapterText });
const client = new Anthropic();
const stream = client.messages.stream({
  messages: [{ role: "user", content: prompt }],
  model: "MiniMax-M2.7",
  max_tokens: 8192,
});
for await (const chunk of stream) {
  if (chunk.type === "content_block_delta" && chunk.delta.type === "text_delta") {
    process.stdout.write(chunk.delta.text);
  }
}

2. Identify Appellations:
   For each unique identifier you find, identify the three key components:
   - Source: The character that _uses_ the identifier (the speaker or thinker). You will record their name as it appears in the text.
   - Target: The character that is _being referred to_ by the identifier. You will record their name as it appears in the text.
   - Appellation: The description of the identifier itself (see step 3).
   Exclude overly generic phrases (e.g., "sir", "the man", "the woman", "the place") and generic insults or derogatory terms (e.g., "idiot", "fool") that could refer to multiple characters. Only include identifiers that clearly and specifically refer to a single named character.
