Agentic Coding 16: The Expert Tells

Most operators learn to control the task — the best learn to control the system that does the task. This lesson reveals four rare, high-impact techniques drawn from 236 expert sessions: the anti-hallucination ground-truth check, economic pushback, confounder injection, and time-window regression. Master these tells and you'll catch the silent failures that trip up even strong agentic developers.

Where you'll use it

• Verifying an agent actually completed a background job before acting on results
• Forcing cost audits on elaborate AI-proposed architectures
• Preventing models from misinterpreting test results with missing context
• Debugging regressions by anchoring the model to recent code changes
• Distinguishing between a task being narrated as complete versus actually complete
