Add a maintainers script to safely promote high-confidence legacy risk labels from unknown to concrete values, cover it with tests, and regenerate the canonical skill artifacts and plugin copies. This reduces the legacy unknown backlog without forcing noisy classifications that still need manual review.
Import and normalize new skills from anthropics/skills, marketingskills, claude-seo, and obsidian-skills.
Align imported skills to repository validation rules, document provenance, and sync generated registry artifacts after the import.
