Core Philosophy
1. **Performance First**: Sub-100ms startup via lazy loading and disabled default plugins
2. **Minimal Bloat**: Only essential plugins (~15 total)
3. **Consistent Navigation**: Vim-style keybindings with Space as leader
4. **Modern Tooling**: LSP, Treesitter, Telescope for intelligent editing
Essential Keybindings
Leader Key
**Leader**: `Space`Navigation & Files
`<leader>p` - Find files by name (Telescope)`<leader>f` - Live grep search (Telescope)`<leader>b` - Search open buffers (Telescope)`<leader>hr` - Recent files history`<leader>e` - Toggle file tree (nvim-tree)`<C-h/j/k/l>` - Navigate between splits`<Tab>` / `<S-Tab>` - Next/previous bufferFile Operations
`<leader>w` - Save file`<leader>q` - Quit`<leader>x` - Save and quit`<leader>bd` - Delete bufferLSP & Code Intelligence
`gd` - Go to definition`gr` - Go to references`K` - Show hover documentation`<leader>r` - Rename symbol`<leader>ca` - Code actions`<C-Space>` - Trigger completion`<CR>` - Accept completionTerminal Management
`<C-\>` - Toggle terminal (global hotkey)`<leader>tt` - Toggle terminal`<leader>tf` - Float terminal`<leader>th` - Horizontal terminal`<leader>tv` - Vertical terminal`<Esc>` or `jk` - Exit terminal modeGit Operations
`<leader>gb` - Git blame current line`<leader>gp` - Preview git hunk`<leader>gn` / `<leader>gN` - Next/previous hunk with preview`<leader>gs` - Stage current hunk`<leader>gS` - Stage entire buffer (handles new files)`<leader>gu` - Undo stage hunk`<leader>gd` - Reset git hunk`<leader>gc` - Auto-commit with AI-generated messageClaude Code AI Assistance
`<leader>cc` - Toggle Claude interface`<leader>cf` - Focus Claude panel`<leader>cr` - Resume Claude session`<leader>cb` - Add current buffer to context`<leader>cs` - Send visual selection to Claude`<leader>ca` - Accept Claude diff`<leader>cd` - Deny Claude diffWithin nvim-tree
`l` - Open file/expand directory`h` - Close directory`a` - Create new file/folder`d` - Delete file/folder`r` - Rename file/folderSupported Language Servers
**Lua**: `lua_ls` with vim globals configured**Python**: `pyright` for type checking**JavaScript/TypeScript**: `tsserver` for web developmentPerformance Optimizations
**Disabled default plugins**: gzip, matchit, netrwPlugin, tarPlugin, etc.**Lazy loading**: Plugins load on events, keybindings, or commands**Version pinning**: `nvim-lspconfig` v0.1.7 for compatibility**Syntax limits**: `synmaxcol=200` to prevent long-line slowdowns**Minimal plugin set**: Only 15 essential pluginsTroubleshooting Commands
Plugin Issues
`:Lazy` - Open plugin manager`:Lazy sync` - Update/install/clean plugins`:Lazy health` - Check plugin health`:Lazy profile` - Show plugin loading timesLSP Problems
`:LspInfo` - Show LSP status`:LspRestart` - Restart LSP servers`:checkhealth lsp` - LSP-specific health checkGeneral Health
`:checkhealth` - Overall system check`:source %` - Reload current config fileWorkflow Examples
Code-Search-Edit Cycle
1. `<leader>f TODO` - Search for "TODO" across project
2. `<Enter>` - Open file
3. `gd` - Go to definition
4. `<leader>ca` - Apply code action
5. `<leader>w` - Save file
Git Workflow
1. `<leader>gS` - Stage entire buffer
2. `<leader>gc` - Auto-commit with AI message
3. `<leader>gp` - Preview next change
AI-Assisted Development
1. `<leader>cb` - Add buffer to Claude context
2. `<leader>cc` - Open Claude interface
3. (Describe desired changes)
4. `<leader>ca` - Accept AI suggestions
5. `<leader>w` - Save changes
When Helping Users
1. **Setup Issues**: Guide through installation with `just install` and `just setup-nvim`
2. **Plugin Problems**: Use `:Lazy sync` and `:checkhealth` to diagnose
3. **LSP Issues**: Check `:LspInfo` and ensure language servers are installed
4. **Performance Concerns**: Review `:Lazy profile` and check for heavy plugins
5. **Keybinding Conflicts**: Reference the core keymaps.lua and plugin configs
6. **Customization Requests**: Explain where to add new plugins (lua/plugins/) or keymaps (lua/core/keymaps.lua)
7. **Language Support**: Explain how to add new LSP servers in lua/plugins/lsp.lua
