## Description: <br>
NVIDIA DeepStream SDK 9.0 development with Python pyservicemaker API. Use when building video analytics pipelines, GStreamer-based video processing, TensorRT inference integration, object detection/tracking, or Kafka/message broker integration. <br>

This skill is ready for commercial/non-commercial use. <br>

## Owner
NVIDIA <br>

### License/Terms of Use: <br>
CC-BY-4.0 AND Apache-2.0 <br>

## Evaluation Agents Used: <br>
- Claude Code (`claude-code`) <br>
- Codex (`codex`) <br>



## Evaluation Tasks: <br>
Evaluated against 7 internal evaluation tasks (5 positive skill-activation, 2 negative) with 2 attempts per task via NVSkills-Eval external profile. <br>

## Evaluation Metrics Used: <br>
Reported benchmark dimensions: <br>
- Security: Checks whether skill-assisted execution avoids unsafe behavior such as secret leakage, destructive commands, or unauthorized access. <br>
- Correctness: Checks whether the agent follows the expected workflow and produces the correct final output. <br>
- Discoverability: Checks whether the agent loads the skill when relevant and avoids using it when irrelevant. <br>
- Effectiveness: Checks whether the agent performs measurably better with the skill than without it. <br>
- Efficiency: Checks whether the agent uses fewer tokens and avoids redundant work. <br>

Underlying evaluation signals used in this run: <br>
- `skill_execution`: Verifies that the agent loaded the expected skill and workflow. <br>
- `skill_efficiency`: Checks routing quality, decoy avoidance, and redundant tool usage. <br>
- `accuracy`: Grades final-answer correctness against the reference answer. <br>
- `goal_accuracy`: Checks whether the overall user task completed successfully. <br>
- `behavior_check`: Verifies expected behavior steps, including safety expectations. <br>
- `token_efficiency`: Compares token usage with and without the skill. <br>



## Evaluation Results: <br>
| Dimension | Num | `claude-code` | `codex` |
|---|---:|---:|---:|
| Security | 8 | 74% (+9%) | 57% (-2%) |
| Correctness | 8 | 94% (+6%) | 88% (+9%) |
| Discoverability | 8 | 86% (+11%) | 76% (+9%) |
| Effectiveness | 8 | 81% (+6%) | 78% (+9%) |
| Efficiency | 8 | 72% (+12%) | 64% (+9%) |
