• Wraps the official obsidian CLI instead of a 4-5k LOC Lua reimplementation
• Real Obsidian search index, backlinks, templates, and Bases via IPC
• 122 plenary tests across 12 spec files with CI integration
• blink.cmp wiki link completion and Snacks picker integration
• Plugin manager that installs Obsidian community plugins from Neovim

AI workflow analyzer with research-backed criteria and exportable build specs

Describe any business process — sajj decomposes it into steps, scores each against four boolean criteria (structured, deterministic, low-risk, no authority), and generates a full build spec you can paste into Claude Code or Cursor. Free, no signup, feeds graduate research on AI-human workflow boundaries at AIM.

• Four-criteria assessment model (green / yellow / red tiers derive directly from the booleans)
• Build Spec exporter generates a full context-engineering prompt for Claude Code or Cursor
• 208 workflow suggestions across 24 industries, 10-language UI
• 72 Playwright end-to-end tests covering landing, analysis, feedback, corrections
• Correction feedback loop feeds a Supabase research dataset on LLM decomposition accuracy

Dark Neovim colorscheme inspired by Citruszest and Ghostty terminal colors

Vibrant citrus accents on a true-dark ground. Treesitter and LSP semantic highlights, plugin support for Telescope, Snacks, Lazy, Which-key, Noice, GitSigns, Mini, and IndentBlankline. Terminal colors exported so your shell, editor, and terminal all agree.

• Treesitter + LSP semantic token coverage
• Terminal colors exported for shell + editor consistency
