+# AGENTS.md
+
+This is a personal Neovim configuration targeting **Neovim 0.12+**. It lives at `~/.config/nvim` and is **not** a traditional software project — there is no build system, test suite, or package manager outside Neovim itself.
+
+## Critical Architecture Notes
+
+- **Plugin manager**: Neovim 0.12+ built-in `vim.pack` (not lazy.nvim / packer). Plugins are declared in `lua/pack.lua` via `vim.pack.add({ urls }, { load = false })` and tracked in `nvim-pack-lock.json`.
+- **Custom lazy-loading**: `lua/lazy.lua` is a ~35-line custom framework (unrelated to lazy.nvim). It provides `load()`, `on_event()`, `on_keys()`, `on_cmd()` and tracks loaded modules in `M._loaded`.
+- **Mini.nvim monorepo**: Most UI/functionality comes from the single `mini.nvim` package. Its submodules (starter, pick, extra, files, icons, notify, cmdline, completion, snippets, diff, surround, ai, cursorword, pairs) are configured individually in `lua/pack.lua` or on-demand.
+
+## File Loading Order
+
+```
+init.lua      → disables ~20 built-in plugins, sets colorscheme, loads core modules
+options.lua   → global vim options, yank highlighting, fold settings
+keymaps.lua   → keymaps (leader = space)
+autocmds.lua  → cursor restore, comment continuation, fold setup
+usercmds.lua  → :PackAdd, :PackDel, :PackUpdate
+pack.lua      → plugin declarations + lazy-loading bindings
+```
+
+## Plugin Commands
+
+```vim
+:PackAdd user/repo       " add plugin
+:PackDel plugin-name     " delete plugin
+:PackUpdate [name]       " update all or specific plugin
+:ExColors!               " extract current colorscheme to optimized ex-colors
+```
+
+## Validation & Debugging
+
+```bash
+# Syntax check init.lua (run from repo root)
+nvim --headless -c 'lua dofile("init.lua")' -c 'qa!'
+
+# Check a specific module
+nvim --headless -c 'lua require("pack")' -c 'qa!'
+
+# Health check
+nvim --headless -c 'checkhealth' -c 'qa!'
+
+# Measure startup time
+nvim --startuptime /tmp/startup.log +q
+```
+
+There is no traditional lint, typecheck, or test command. The validation commands above are the only verification steps.
+
+## Lazy-Loading Strategy
+
+When adding new plugins that should load lazily, use the custom framework in `lua/lazy.lua` — do **not** use lazy.nvim patterns.
+
+| Trigger       | Plugins / Modules                    |
+|---------------|--------------------------------------|
+| `VimEnter`    | treesitter, lsp, icons               |
+| `InsertEnter` | completion, snippets, pairs          |
+| `BufReadPost` | diff, surround, ai, cursorword       |
+| `BufWritePre` | conform (format-on-save)             |
+| Key press     | pick, files, fugitive, grugfar       |
+| Command       | ex-colors (`:ExColors`)              |
+
+## LSP & Formatting
+
+- **LSP servers enabled**: html, cssls, gopls, vtsls, rust_analyzer, lua_ls, taplo, svelte, dartls, kotlin_lsp
+- **Lua LSP**: `vim` is declared as a global in `lua_ls` settings to suppress "Undefined global" diagnostics
+- **Formatters by filetype**:
+  - `lua` → stylua
+  - `go` → gofumpt, goimports
+  - `js/ts/json/css/html/md` → biome (if `biome.json` found) or prettier
+  - `toml` → taplo
+- **Toggle autoformat**: `vim.b[bufnr].autoformat = false` (buffer) or `vim.g.autoformat = false` (global)
+
+## Key Conventions
+
+- Startup performance is a priority. Heavy modules are deferred to `VimEnter` or later. Clipboard is set via `vim.schedule()` to avoid blocking.
+- The active colorscheme is `ex-catppuccin-mocha`, defined in `colors/ex-catppuccin-mocha.lua`.
+- Comments and UI strings are in **Chinese**.
