Agent Skills: issue-md-writer

Create and draft markdown-based issue documents (bug reports, feature plans, RFCs, ADRs, tasks, retrospectives) in the top-level `.issues/` folder. Use this skill whenever you need to document software issues, feature proposals, architectural decisions, work items, or post-mortems. Includes templates, metadata indexing, and structured YAML frontmatter. Different from issue tracker systems — this is for archival, decision-making, and knowledge base documents.
