Code-Defined Agent Skills Sample

This sample demonstrates how to define Agent Skills entirely in code using AgentInlineSkill.

What it demonstrates

  • Creating skills programmatically with AgentInlineSkill — no SKILL.md files needed
  • Static resources via AddResource with inline content
  • Dynamic resources via AddResource with a factory delegate (computed at runtime)
  • Code scripts via AddScript with a delegate handler
  • Using the AgentSkillsProvider constructor with inline skills

Skills Included

unit-converter (code-defined)

Converts between common units using multiplication factors. Defined entirely in C# code:

  • conversion-table — Static resource with factor table
  • conversion-policy — Dynamic resource with formatting rules (generated at runtime)
  • convert — Script that performs value × factor conversion

Running the Sample

Prerequisites

  • .NET 10.0 SDK
  • Azure OpenAI endpoint with a deployed model

Setup

export AZURE_OPENAI_ENDPOINT="https://your-endpoint.openai.azure.com/"
export AZURE_OPENAI_DEPLOYMENT_NAME="gpt-5.4-mini"

Run

dotnet run

Expected Output

Converting units with code-defined skills
------------------------------------------------------------
Agent: Here are your conversions:

1. **26.2 miles → 42.16 km** (a marathon distance)
2. **75 kg → 165.35 lbs**
