+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Architecture Overview
+
+This is a Neovim configuration written in Lua using Neovim's native package manager (`vim.pack.add`). The configuration is modular, with each feature organized into separate Lua files.
+
+### Core Structure
+- `init.lua` - Main entry point, loads all modules and handles host-specific theming
+- `lua/` - All Lua modules
+  - `options.lua` - Vim options, settings, and autocommands
+  - `plugins.lua` - Plugin definitions and basic setup using `vim.pack.add()`
+  - `keymaps.lua` - All key mappings including leader, Meta-X, Ctrl-X, and function key bindings
+  - `lsp.lua` - LSP configuration (lua_ls, gopls) with lsp_signature
+  - `completion.lua` - nvim-cmp completion setup
+  - `treesitter.lua` - Treesitter configuration
+  - `utils/` - Utility functions and overrides
+    - `t3_functions.lua` - Custom functions for file finding, note capture, and navigation
+    - `t3_overrides.lua` - Custom overrides
+    - `reload.lua` - Configuration reloading utilities
+
+### Key Features
+- **Multi-host theming**: Different TokyoNight themes based on hostname (xps13 uses "moon", Titan uses "storm")
+- **TTY compatibility**: Automatic fallback to console-friendly themes and no icons when running in Linux console
+- **Dual picker system**: Uses both FzfLua and Mini.pick for different workflows
+- **Comprehensive key bindings**: Leader-based, Meta-X (Emacs-style), Ctrl-X, and function keys
+- **Claude Code integration**: Built-in support with dedicated keymaps under `<leader>a`
+- **Note-taking workflow**: Custom functions for capturing notes and snippets
+
+### Plugin Management
+Uses Neovim's native package manager (`vim.pack.add`). No external package manager like lazy.nvim or packer.nvim is used.
+
+### Key Bindings Architecture
+- **Leader key**: Space (`<leader>` = `" "`)
+- **Leader mappings**: Organized by category (files, buffers, grep, git, tabs, AI)
+- **Meta-X mappings**: Emacs-style command palette using Telescope
+- **Ctrl-X mappings**: Additional workflows using Mini.pick
+- **Function keys**: Quick access to common operations
+
+### LSP Configuration
+- Enabled for Lua (`lua_ls`) and Go (`gopls`) with comprehensive settings
+- Uses lsp_signature for parameter hints
+- Glance plugin for references/definitions with custom keymaps (`gR`, `gD`, `gY`, `gM`)
+
+## Development Commands
+
+This configuration doesn't have traditional build/test commands as it's a Neovim config. Key operations:
+
+### Configuration Management
+- Reload config: Use the reload utilities in `lua/utils/reload.lua`
+- Test changes: Restart Neovim or use `:luafile %` for individual files
+
+### Plugin Management
+- Add plugins: Edit `lua/plugins.lua` and add to the `vim.pack.add()` table
+- Plugin updates: Restart Neovim (native package manager handles updates)
+
+### Custom Functions
+- `:NeorgCapture` - Capture notes using the custom note-taking workflow
+- `:CaptureSnip` - Capture code snippets for LuaSnip
+- Various `t3_*` functions for file navigation and workflows
+
+## Important Conventions
+
+### File Organization
+- All Lua code goes in `lua/` directory
+- Utilities and custom functions in `lua/utils/`
+- Each major feature gets its own file (lsp.lua, completion.lua, etc.)
+
+### Keymaps
+- Use descriptive `desc` fields for all keymaps (for which-key integration)
+- Organize leader keymaps by category with sub-prefixes
+- Function keys for frequently used operations
+
+### Host-Specific Behavior
+The config detects hostname and adjusts theming accordingly. When adding host-specific features, follow the pattern in `init.lua` lines 17-45.
+
+### TTY Compatibility
+The configuration automatically detects TTY environments and disables icons/complex UI elements. When adding new UI features, consider TTY fallbacks.
