Show HN: KatmerCode – Claude Code in Obsidian with academic research skills

I built an Obsidian plugin for my wife (academic researcher). It embeds Claude Code as a sidebar chat using the Agent SDK, and ships with 7 slash-command skills: - /peer-review — 8-criteria manuscript evaluation with radar chart - /cite-verify — checks references against CrossRef, Semantic Scholar, OpenAlex - /research-gap — finds gaps in the literature with feasibility scoring - /journal-match — suggests target journals from your reference profile - /lit-search — parallel search across arXiv, PubMed, Semantic Scholar, OpenAlex - /citation-network — interactive citation graph - /abstract — generates abstracts in 5 formats Also has inline diff editing (word-level track changes in the editor) and MCP server support.
