The Cheapest-Fix-First Diagnostic Sequence

Identify, diagnose, and resolve issues with underperforming prompts or poor outputs

SUBy Solomon UdohReviewed by Solomon UdohAI-assisted · human-reviewed
In short
The diagnostic sequence is an ordered checklist run before concluding a task is impossible: re-read the prompt for under-specification, check the conversation length for context overload, check the feature and model, check the configuration for drift, and only then question whether the task fits Claude at all. The order runs from the cheapest check to the most expensive conclusion, so the common, low-cost causes are ruled out before the rare, high-cost one is reached.
