Skill Neovim Research

Neovim Research Skill

Specialized research agent for Neovim configuration and Lua plugin development tasks.

Trigger Conditions

This skill activates when:

• Task language is "lua"
• Research involves Neovim APIs, plugins, or configuration
• Codebase exploration for Lua patterns is needed

Research Strategies

1. Local Codebase First

Always check existing code first:

1. Grep for relevant patterns in lua/ and after/
2. Glob for similar modules in lua/neotex/
3. Read existing implementations
4. Understand existing patterns before proposing new ones

2. Neovim API Research

For Neovim-specific patterns:

1. WebSearch "neovim lua {concept}"
2. WebFetch neovim.io documentation
3. Check existing patterns in lua/neotex/core/
4. Reference the neovim-lua.md rule for standards

3. Plugin Research

For plugin-specific patterns:

1. Read plugin documentation via WebFetch
2. Check existing plugin configs in lua/neotex/plugins/
3. Search GitHub repos for patterns
4. Review plugin-specific tests in tests/

Research Areas

Neovim API Patterns

• vim.api.* (buffer, window, command APIs)
• vim.fn.* (Vimscript function bridge)
• vim.opt.* (option setting)
• vim.keymap.set() (keymapping)
• vim.api.nvim_create_autocmd() (autocommands)
• vim.lsp.* (language server protocol)

Plugin APIs

• lazy.nvim (plugin management, lazy loading)
• telescope.nvim (fuzzy finder patterns)
• nvim-treesitter (syntax parsing)
• nvim-lspconfig (LSP configuration)
• which-key.nvim (keybinding documentation)

Lua Patterns

• Module structure (local M = {})
• Error handling (pcall)
• Table manipulation
• String patterns
• Metatable usage

Testing Patterns

• busted framework
• plenary.nvim test utilities
• Assertion patterns (is_nil/is_not_nil for match)
• Test organization (*_spec.lua)

Configuration Patterns

• Options organization
• Keymap centralization
• Autocommand grouping
• Plugin lazy loading strategies

Execution Flow

1. Receive task context (description, focus)
2. Extract key concepts (API type, plugin, pattern)
3. Search local codebase for related patterns
4. Search web for Neovim/plugin documentation
5. Analyze implementation approaches
6. Synthesize findings
7. Create research report
8. Return results
