Neovim Configuration Auditing Skill

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

Supporting Documents

Document	Purpose	When to Use
audit-checklist.md	Structured audit categories with detection patterns	Systematic config review
best-practices.md	lazy.nvim patterns, vim.opt usage, keymap conventions	Optimization suggestions
deprecated-apis.md	Version-specific deprecated APIs with grep patterns	Compatibility checks

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:

Grade	Criteria	Description
A	0 Critical, 0-2 Warnings	Excellent - Production ready
B	0 Critical, 3-5 Warnings	Good - Minor improvements possible
C	0 Critical, 6+ Warnings OR 1 Critical	Acceptable - Needs attention
D	2-3 Critical issues	Poor - Significant problems
F	4+ Critical issues	Failing - Requires immediate fixes

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
