Establish a baseline for interpreting agent library import rates

Establish a quantitative baseline for the expected frequency of library imports in agent-authored pull requests across TypeScript/JavaScript, Python, Go, and C#, to enable assessment of whether the observed import rates indicate overuse, underuse, or appropriate use.

Background

In analyzing import behavior, the authors report substantial variation across languages but note the absence of an established baseline for how often libraries should be reused by agents, which limits interpretation of whether agents are overusing or underusing libraries.

This lack of baseline leaves a methodological gap: without a reference rate, empirical findings on import frequency cannot be framed as preferable, excessive, or insufficient usage, motivating the need for a benchmark to contextualize agent behavior.

References

Although reusing libraries is a core skill for professional developers, there is no established baseline for how often this should occur, making it difficult to assess whether these rates indicate overuse, underuse, or neither.
