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.
