AI Engineering & Harnesses

Use agents to build and check software, or design the tools and rules that let a running agent do a job.

Start here

Use an agent to build software. Give a coding agent one small change, a concrete example of the expected result, and a check it can run. Review the diff and the check before accepting the change.
Design a system for an agent to operate. Write down one task, such as reading a report. The control plane is the part of the system that checks who is asking, what they can do, and what gets recorded.
