Meet Your Claw: A Harness in Three Lines of C#

One call to AsHarnessAgent gives us the whole agentic loop. From there we add the first three abilities: a custom get_stock_price tool, the built-in web search for market news, and planning with a todo list plus plan and execute modes.

That is enough to turn a vague request like “review my watchlist and suggest something to add” into a tracked, step-by-step plan. We wire the agent to a Microsoft Foundry chat client, run it in the shared harness console, and set up the companion repo so everyone starts on the same SDK version.
