A curated collection of resources, patterns, and templates for building reliable scaffolding for agents. Harness engineering is the discipline of designing the systems surrounding an agent—such as context delivery, tool interfaces, planning artifacts, verification loops, memory systems, and sandboxes—that determine its success or failure on real tasks. This focus is on the harness rather than the model.
- Design primitives for loops, planning, and memory
- Reference implementations and tutorials
- Security, sandboxing, and permissions
- Evaluation, verification, and observability
- Task runners and orchestration
- Human-in-the-loop and production operations
