Why Optix?

Production issues are hard to debug — scattered telemetry, unfamiliar tools, and context switching between portals. Optix brings Azure Application Insights directly into your terminal, so you can go from symptom to root cause to fix without leaving your workflow.

• Find what's broken — surface slow requests, errors, and anomalies from Application Insights telemetry
• Understand why — drill into profiler hot paths, snapshot call stacks, and distributed traces at the method level
• Fix it faster — get actionable code-level recommendations, not just dashboards

What's Included

Skills

Skills are organized into three categories that form a natural workflow: Setup → Explore → Investigate.

🔧 Setup — "Am I ready?" (recommended)

These skills help ensure Azure monitoring tools are enabled and configured. They are recommended but not strictly required — other skills will guide you to enable them when needed.

🔍 Exploring — "What's wrong?"

Discover performance issues, anomalies, and optimization opportunities across your application.

🔬 Investigating — "Why is it wrong?"

Drill into specific issues — profiler traces, snapshots, and distributed operations.

Agent

• optix-optimizer — A performance optimization specialist agent that combines all skills

Prerequisites

• GitHub Copilot CLI installed and authenticated
• Azure CLI installed and logged in (az login)
• An Azure subscription with Application Insights configured

The following are recommended but not required — skills will prompt you to enable them when needed:

• Application Insights Profiler for performance analysis
• Snapshot Debugger for exception debugging

# Install GitHub Copilot CLI
winget install GitHub.CopilotCLI

# Install Azure CLI
winget install Microsoft.AzureCLI

# Authenticate
copilot auth login
az login

Installation

# Add the marketplace
copilot plugin marketplace add microsoft/code-optimizations-skills

# Install all skills + agent
copilot plugin install optix@microsoft-optix

copilot plugin install optix-explore@microsoft-optix       # Exploring skills + agent
copilot plugin install optix-investigate@microsoft-optix    # Investigating skills + agent
copilot plugin install optix-setup@microsoft-optix          # Setup skills + agent

Usage

Once installed, the skills are automatically available in Copilot CLI conversations:

# Investigate a slow endpoint
copilot "Help me find out why my API is slow"

# Analyze a profiler trace
copilot "Get the hot path from my latest profiler trace"

# Download a trace for offline analysis
copilot "Download a profiler trace from my App Insights resource"

# Enable the profiler on your app
copilot "Help me enable the Application Insights Profiler"

# Download a snapshot for offline debugging
copilot "Download a snapshot dump from my App Insights resource"

# Inspect exception details from a snapshot
copilot "Show me the exception, call stack and relevant variables from my latest snapshot"

# Enable the Snapshot Debugger on your app
copilot "Help me enable the Snapshot Debugger"

# Analyze AI agent performance
copilot "Analyze my AI agent telemetry for anomalies"

# Explore errors and failures
copilot "What errors are happening in my application?"

# Deep analysis of a distributed trace
copilot "Do a deep analysis of operation ID abc-123"
