Repeatability
High
KeyError debugging follows a consistent diagnostic pattern: inspect key access, validate column names, check CSV headers, and add guards. The structure is the same across instances even if the specific script differs.
Ambiguity Tolerance
High
Success is unambiguous — the corrected code runs without the KeyError. The agent can verify this logically by tracing the fix, and the user can confirm by running the script.
Data & Tool Availability
Medium
The agent needs the actual Python script and ideally a sample CSV file to diagnose accurately. If only a description is provided, the fix may be generic rather than precise, but even then it's often sufficient.
Error Cost
Low
The output is a code suggestion, not an executed action. The user reviews and applies the fix themselves, so a wrong answer is easily caught and costs nothing beyond wasted time.
Human Judgment Required
Low
KeyError root causes in CSV processing are a narrow, well-understood problem space. No taste, ethics, or relationship context is needed — just technical pattern recognition that AI does well.
