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
Gather Environment Info
- Neovim version (determines which deprecated APIs apply)
- Plugin manager type (lazy.nvim, packer.nvim, etc.)
- Config structure (single file vs modular)
Run Category Audits
- Follow audit-checklist.md categories in order
- Use grep patterns to detect issues programmatically
- Note severity for each finding
Check Version Compatibility
- Reference deprecated-apis.md for user's Neovim version
- Flag APIs deprecated OR removed in their version
Apply Best Practices
- Compare against best-practices.md
- Suggest optimizations where applicable
Calculate Grade
- Count Critical/Warning/Suggestion issues
- Apply scoring criteria above
- Provide overall health assessment
