# Technical Document Extraction: Token Usage and Function Calls Analysis
## 1. Document Header
* **Title:** Token Usage and Function Calls in a Troubleshooting Copilot Dialog Session
* **Primary Language:** English
* **Secondary Language:** Italian (contained within function call parameters)
## 2. Chart Metadata and Structure
* **Chart Type:** Multi-series Line Graph with data labels and annotations.
* **X-Axis (Horizontal):** "Dialog Turn" (Scale: 1 to 8, integer increments).
* **Y-Axis (Vertical):** "Tokens Count" (Scale: 0 to 4000, increments of 500).
* **Legend Location:** Top-left corner.
* **Legend Categories:**
* **Prompt Tokens:** Yellow line with solid circle markers (●).
* **Completion Tokens:** Green line with open circle markers (○).
* **Total Tokens:** Red line with open triangle markers (△).
## 3. Data Series Analysis and Trends
### Series 1: Total Tokens (Red Line, △)
* **Trend:** Sharp upward slope from Turn 1 to 2, followed by a plateau at Turn 3. Another sharp increase occurs at Turn 4, followed by a steady, gradual upward slope through Turn 8.
* **Data Points:**
* Turn 1: 944
* Turn 2: 2471
* Turn 3: 2515
* Turn 4: 3123
* Turn 5: 3202
* Turn 6: 3289
* Turn 7: 3338
* Turn 8: 3434
### Series 2: Prompt Tokens (Yellow Line, ●)
* **Trend:** Closely mirrors the "Total Tokens" line, remaining just below it throughout the session. This indicates that the majority of the token volume is driven by the prompt/context.
### Series 3: Completion Tokens (Green Line, ○)
* **Trend:** Low and relatively stable near the bottom of the Y-axis (0-250 range). It shows minor fluctuations, with small peaks at Turn 4 and Turn 8.
## 4. Embedded Function Call Annotations
| Dialog Turn | Function Call Text | Language Note |
| :--- | :--- | :--- |
| **Turn 1** | `retrieve_troubleshooting_instructions({'query': 'C'è qualcosa che si è incastrato sotto il nastro.'})` | **Italian Translation:** "There is something stuck under the belt." |
| **Turn 4** | `retrieve_part_details({'device_code': 'CNV-NT2024-A'})` | English |
| **Turn 8** | `build_report({...})` | English |
| **Turn 8** | `handoff_report({})` | English |
## 5. Component Isolation & Logic Check
* **Logic Check:** Total Tokens (Red) = Prompt Tokens (Yellow) + Completion Tokens (Green).
* **Verification:** At Turn 1, Total is 944. Prompt is slightly below 1000, and Completion is near 0. At Turn 8, Total is 3434. Prompt is approx. 3200, and Completion is approx. 200. The math visually aligns across all points.
## 6. Summary of Findings
The graph illustrates a cumulative or context-heavy dialog session where the token count increases significantly as the conversation progresses. The most substantial jumps in token usage occur at Turn 2 and Turn 4. The "Total Tokens" are dominated by "Prompt Tokens," suggesting that the system is maintaining a growing conversation history or retrieving large amounts of context to process the troubleshooting request. Function calls are strategically placed at the start, middle, and end of the session to retrieve instructions, part details, and finally generate/handoff a report.
