My Agent Shipped 3 PRs in an Evening. 40% of My Messages Were Corrections.

Let It Break, Part 3

Last night an agent session I was running submitted three pull requests to pnp/sp-dev-fx-webparts — an MCP client web part, an Azure AI Agent chat, and an M365 Copilot Agent chat. All three passed automated validation. I didn't change a line of code.

On paper: a great session. Then I exported the transcript and counted my own messages.

710 messages total. Thirty were mine. Twelve of those thirty were me telling the agent it was doing the wrong thing.

That's a 40% steering rate. For a session that shipped everything.
