Why Memory Ownership Is Becoming a Harness Decision
As harnesses absorb session management, context compaction, and persistent memory, the choice of harness is increasingly a choice about who owns your agent's memory.

The Self-Improving Harness: When Agent Infrastructure Learns to Optimize Itself
Agent harnesses are evolving from static scaffolding into self-modifying systems that mine their own failures, generate evals, and hill-climb their own performance — reshaping what it means to build and maintain agents in production.
April 11, 2026The Harness-Model Training Loop: Why the Boundary Between Agent Infrastructure and Model Weights Is Collapsing
Open models reaching agent parity, task-specific harness engineering, and trace-driven fine-tuning are merging what used to be separate concerns into a single iterative loop — with major implications for how teams build and operate agents.

How sequenced specialist agents with defined handoff contracts and backward feedback loops produce more reliable results than flat swarms or orchestrator/worker splits.
April 2, 2026When Evals Become Optimization Targets
Optimizing agent harnesses against a fixed eval suite triggers Goodhart's Law — the same dynamic that eroded search quality through SEO. How adversarial eval co-evolution can help.
March 28, 2026Strategic Forgetting in Agent Memory Systems
Production experience and neuroscience research both suggest that selective forgetting — not total recall — is a key architectural primitive for agent memory.
March 28, 2026When the Harness Becomes the Differentiator
