Neovim Configuration Auditing Skill

Neovim Configuration Auditing Skill

Systematic configuration analysis for identifying issues, optimizations, and deprecated API usage in Neovim setups.

Quick Validation Commands

Run these headless commands for rapid assessment:

# Get Neovim version
nvim --version | head -1

# Get config path
nvim --headless -c "lua print(vim.fn.stdpath('config'))" -c "qa" 2>&1

# Count Lua files in config
find ~/​.config/​nvim -name "*.lua" 2>/​dev/​null | wc -l

# Count plugins (lazy.nvim)
ls ~/​.local/​share/​nvim/​lazy 2>/​dev/​null | wc -l

# Check for deprecated vim.api.nvim_buf_set_option usage
grep -rn "nvim_buf_set_option\|nvim_win_set_option" ~/​.config/​nvim --include="*.lua" 2>/​dev/​null | head -10

# Check startup time
nvim --startuptime /​tmp/​nvim-startup.log +q && tail -5 /​tmp/​nvim-startup.log

# Validate Lua syntax in config
nvim --headless -c "lua dofile(vim.fn.stdpath('config')..'/​init.lua')" -c "qa" 2>&1

# Check for error on startup
nvim --headless -c "qa" 2>&1 | head -20

Scoring Criteria

Assign grades based on issue severity and count:

Issue Severity Definitions

Critical: Security risks, breaking deprecated APIs (removed in current version), runtime errors Warning: Performance issues, deprecated APIs (still working), code style violations Suggestion: Optional improvements, modern alternatives, organization tips

Audit Workflow

1. Gather Environment Info

   • Neovim version (determines which deprecated APIs apply)
   • Plugin manager type (lazy.nvim, packer.nvim, etc.)
   • Config structure (single file vs modular)

2. Run Category Audits

   • Follow audit-checklist.md categories in order
   • Use grep patterns to detect issues programmatically
   • Note severity for each finding

3. Check Version Compatibility

   • Reference deprecated-apis.md for user's Neovim version
   • Flag APIs deprecated OR removed in their version

4. Apply Best Practices

   • Compare against best-practices.md
   • Suggest optimizations where applicable

5. Calculate Grade

   • Count Critical/​Warning/​Suggestion issues
   • Apply scoring criteria above
   • Provide overall health assessment
