The harness as the context manager
Concept
12 Agentic Harness Patterns from Claude Code
The leaked source revealed how a production coding agent is actually assembled. Here are the design patterns behind it.

How Steering Hooks Achieved 100% Agent Accuracy Where Prompts and Workflows Failed
Steering hooks achieved a 100% accuracy pass rate across 600 evaluation runs, compared to 82.5% for simple prompt-based instructions and 80.8% for graph-based workflows.
Today I'm thrilled to open source what I've been working on...
