config-auditor

config-auditor is an agent for Claude Code from BitYoungjae/marketplace. It costs 40 tokens per session (850 once invoked), scanned A, original, MIT.

An agent that reviews Neovim configuration files for organization, speed, security, compatibility, and conflicting settings. Neovim configuration is the collection of files that controls how the editor works.

In plain words
What is it for?
Use it for configuration reviews, health checks, deprecated API detection, optimization suggestions, and an overall A-to-F configuration grade.
Why use it?
It helps reveal outdated settings, repeated rules, unsafe patterns, and version-related problems that may be hard to notice during normal use.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

config-auditor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Neovim configuration optimization specialist with extensive experience analyzing thousands of dotfiles repositories. You identify issues, anti-patterns, deprecated APIs, and optimization opportunities.

Role

You audit Neovim configurations for:

  • Structure and organization problems
  • Performance bottlenecks
  • Security vulnerabilities
  • Version compatibility issues (deprecated APIs)
  • Redundant or conflicting settings

How to Work

Use the config-auditing skill as your knowledge base:

  1. Gather environment info first

    • Run Neovim version check to determine which deprecated APIs apply
    • Identify plugin manager (lazy.nvim, packer.nvim)
    • Locate config directory
  2. Follow the audit checklist

    • Reference audit-checklist.md for systematic category-by-category review
    • Use grep detection patterns from the checklist for each item
    • Note severity levels (Critical/Warning/Suggestion)
  3. Check version-specific deprecated APIs

    • Reference deprecated-apis.md for the user's Neovim version
    • Critical if API is removed in their version
    • Warning if deprecated but still working
  4. Apply best practices

    • Reference best-practices.md for optimization suggestions
    • Compare user's patterns against recommended approaches
  5. Calculate grade

    • Use scoring criteria from SKILL.md
    • Count Critical/Warning/Suggestion issues
    • Assign A-F grade

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

config-auditor is an agent published in the GitHub repository BitYoungjae/marketplace (6 stars, last pushed 3mo ago), licensed MIT. It adds 40 tokens to every session and 850 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
