Agent Skills Sample

This sample demonstrates how to use Agent Skills with a ChatClientAgent in the Microsoft Agent Framework.

What are Agent Skills?

Agent Skills are modular packages of instructions and resources that enable AI agents to perform specialized tasks. They follow the Agent Skills specification and implement the progressive disclosure pattern:

1. Advertise: Skills are advertised with name + description (~100 tokens per skill)
2. Load: Full instructions are loaded on-demand via load_skill tool
3. Resources: References and other files loaded via read_skill_resource tool

Skills Included

expense-report

Policy-based expense filing with spending limits, receipt requirements, and approval workflows.

• references/POLICY_FAQ.md — Detailed expense policy Q&A
• assets/expense-report-template.md — Submission template
