A Claude Code skill that recovers export-blocked Kindle highlights

A new Claude Code skill, published under the l3a0 namespace, successfully recovers export-blocked Kindle highlights. Tested on four books, it extracted 2,432 highlights, including 815 previously blocked (454 truncated, 361 hidden). All blocked highlights were recovered with high accuracy, demonstrating a median residual of 0–1 characters compared to the Kindle app. The skill's development and the reasons behind Kindle's export limits are detailed in "How to Take Back Your Kindle Highlights" on Substack.
