Agent Skills: docs-core

Generate or update the 5 core project knowledge **folders** (overview, architecture, domain, source-base, standards) in ./documents/. Each knowledge area is a folder with 00-index.md + numbered sub-files. Performs autonomous codebase scanning, gap analysis, and produces enterprise-grade documentation for rapid onboarding. Use when user says 'generate docs', 'update docs', 'create project documentation', 'docs-core', '/docs-core', 'onboarding docs', or wants to create/refresh the knowledge base.
