# System Evolution - Readwise EPUB import workflow Updated the shared Codex and Claude readwise skills after the Readwise EPUB upload problem. The skills now prefer Reader URL import through a temporary Google Drive link for Drive-backed EPUB/PDF files, then require explicit tag verification and removal of the temporary public permission. Changed files: - /Users/nickyoung/.codex/skills/readwise/SKILL.md - /Users/nickyoung/.claude/skills/readwise/SKILL.md Verification: the two files are identical and the cross-runtime skill sync checker reports OK.
