File-Based Agent Skills Sample

This sample demonstrates how to use file-based Agent Skills with a ChatClientAgent.

What it demonstrates

  • Discovering skills from SKILL.md files on disk via AgentFileSkillsSource
  • The progressive disclosure pattern: advertise → load → read resources → run scripts
  • Using the AgentSkillsProvider constructor with a skill directory path and script runner
  • Running file-based scripts (Python) via a subprocess-based executor

Skills Included

unit-converter

Converts between common units (miles↔km, pounds↔kg) using a multiplication factor.

  • references/conversion-table.md — Conversion factor table
  • scripts/convert.py — Python script that performs the conversion

Running the Sample

Prerequisites

  • .NET 10.0 SDK
  • Azure OpenAI endpoint with a deployed model
  • Python 3 installed and available as python3 on your PATH

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 file-based skills
------------------------------------------------------------
Agent: Here are your conversions:

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