The entire premise of this paper is false. They claim that the "hints_text" is used and leaks the answer in Section 2.1.1; however, the authors of SWE-Bench themselves state that this is not used anywhere (Issue #133 on the official SWE-Bench GitHub).

According to the paper:

> 1. Solution leak: represents instances where the solution to the issue is clearly outlined in the issue description or comments on GitHub. Since both the issue descriptions and comments (referred to as hints_text in the SWE-Bench study) are provided as input to the models, these LLM models can extract the solutions directly from this information instead of generating it independently.

And yet, the SWE-Bench authors themselves explicitly state:

> In short, for participating on the SWE-bench leaderboard, using hints_text in any manner is not allowed. Although we don't explicitly say this in the original paper, we also do not make any mention of using the hints_text anywhere.

So, it's a made up issue that would only occur if you deviated from the paper implementation and explicitly added a field called "hints" that isn't used anywhere.

Hmm. For the example they give of solution leakage, sympy issue 16669 aka sympy__sympy-16766[1], the solution actually appears in problem_statement, so it seems to be genuine leakage. But you're right that they claim that hints_text is used, so they may have improperly winnowed out other instances where the solution only appears in hints_text.

[1] Don't ask me why they cited the issue number, 16669, instead of the pull request number, 16766, when only the latter appears in the dataset. This confused me for a bit.
