GitHub Copilot CLI Challenge Submission

This is a submission for the GitHub Copilot CLI Challenge

What I Built

I built a Test-NetConnection interactive assistant that runs continuous network checks to a target host, logs results, and provides both statistical summaries and AI-powered observations. The assistant supports background monitoring tasks, listing active jobs, and on-demand log analysis. It’s designed for quick, repeatable troubleshooting of latency spikes and packet loss without leaving the terminal.

Key features:

/run <host> <minutes> <threshold_ms> starts a background monitoring task.
/list shows active or completed background tasks.
/analysis summarizes logs and uses GitHub Copilot to produce AI observations.
JSONL logging for both raw events and alerts.

Demo

Run the assistant:

python .\tnc_interactiveAssistant.py

Example session:

Start a monitor: /run 8.8.8.8 1 120
List tasks: /list
Analyze logs with AI observations: /analysis

My Experience with GitHub Copilot CLI

I used GitHub Copilot CLI to quickly iterate on command handling, background task orchestration, and the AI analysis flow. It helped me:

Draft the command parsing and task management scaffolding.
Refactor analysis logic into reusable prompt context builders.
Embed GitHub Copilot's agentic workflows to perform analysis (especially useful when you have large dataset)

It accelerated development while keeping the solution focused on a clean CLI experience.
