A coding agent performs well in one repo and badly in another with similar languages. What would you investigate?

Instruction: Describe how you would investigate uneven coding-agent performance across repositories.

Context: Tests how the candidate diagnoses the problem, chooses the safest next step, and reasons through recovery. Describe how you would investigate uneven coding-agent performance across repositories.

I'd compare the conditions around the model before blaming the language or repository. Does the failing repo have current indexes, clear entry points, installed dependencies, runnable tests, and accessible requirements?...

3. Prepare for senior discussions

Explain failure boundaries, recovery, and production choices.
