Anthropic engineer: the longer your agent runs, the costlier its mistakes — build verification in
Roger_M_Taylor · x · 2026-09-18
An Anthropic engineer explains in a 28-minute breakdown how the Claude Code team runs agents that check their own work:
- Core idea: the longer an agent runs, the more expensive its mistakes get — so verification should be built into the artifact itself, not left to human review.
- The talk traces a workflow evolution: Prompting → Loops → Graphs → Self-Verifying Systems, arguing prompting was the old workflow and loop/graph engineering is the next one.
