Forward Deployed, Episode 3: Context Engineering
Forward Deployed
Nano Banana and image-text workflows
Noah and Lance explore Nano Banana's text-on-image ability and new visual agentic workflows like schematics.
Welcome to episode three of Forward Deployed. Noah and Lance dive deep into context engineering—the art and science of filling context windows with just the right information for agents to take the next action.
Key Topics Covered
- Context engineering: Why Karpathy’s term matters more than prompt engineering for agents
- Three core techniques: Reducing context, isolating context, and offloading context to file systems
- Skills vs MCPs: Why progressive disclosure beats loading everything into context
- Claude Diary: Building agent memory through reflection and evolving CLAUDE.md
- Why subagents should isolate context, not anthropomorphize org charts
- Production patterns from Manus: Compaction, file system offloading, and sandbox architecture
- The convergence of agent primitives: Read, write, reduce, and recombine
- Why treating agents like humans works: Dual-use tools and new coworker onboarding
