Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.

Docker and Docker Compose patterns for local development, container security, networking, volume strategies, and multi-service orchestration.

Use up-to-date library and framework docs via Context7 MCP instead of training data. Activates for setup questions, API references, code examples, or when the user names a framework.

Word DOCX create, read, edit, review. Triggers: Word doc, .docx, reports, memos, letters, templates.

Use this skill when the user wants to create an academic paper, research paper, white paper, technical report, policy brief, or any formally structured document with TOC, equations, footnotes, endnotes, or scholarly formatting. Trigger on: 'academic paper', 'research paper', 'white paper', 'technical report', 'policy brief', 'journal paper', 'scholarly document', 'paper with equations', 'paper with footnotes', 'paper with TOC', 'manuscript', 'conference paper'. Output is always a single .docx...
