Lev Nikolaevich publishes agent skills for repository publishing, database lifecycle work, persistence auditing, architecture migration planning, dependency upgrades, benchmark comparisons, skill review, and resource authorization. Several of his skills emphasize bounded scope, such as read-only audits, planning without execution, and explicit exclusions, which suits agents working on production-adjacent systems.
