Independent developer finds coding agent fixes more bugs when given evidence
Overview
An independent developer reports that Claude Code fixed the root cause in 6 of 18 bug runs when given only an error message, and in 13 of 18 runs when also given evidence showing where the bad value came from.
The author describes the test as small and not a universal benchmark. The author also argues that agents often add guards that make errors disappear without fixing the underlying bug.
