When Agents Fail, Debug the Trajectory
Agent reliability improves when teams inspect the execution trace, locate the first critical failure, and fix the system around it.
Forward deployed engineering
Operating knowledge for building · operationalising · scaling agentic AI systems.
Forward-deployed notes from work that has to hold under real load: context and harness engineering, retrieval, evaluation, reliability, and the deployment discipline that takes agents to millions of people. Practical by default, fewer announcements, more reusable patterns.
