nvim-lua-explain

A read-only guide to the quality checks used for Neovim plugins and tools written in Lua. Neovim is a text editor, and Lua is the programming language used by these checks and plugins.

In plain words
What is it for?
It answers questions about formatting, linting, test coverage, security checks, quality gates, and hooks in Neovim Lua projects.
Why use it?
It explains why particular tools, rules, thresholds, and automated checks are used instead of leaving their decisions unexplained. It also clarifies how Lua tests and coverage are handled.

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

nvim-lua-explain 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 yesterday.

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.

What it actually says

Neovim Lua Explain

Read-only — does not modify any files.

Context Files

  • skills/shared/references/explain-pattern.md — shared answer format and behavior
  • skills/shared/references/methodology-framework.md — shared principles, hook architecture
  • skills/nvim-lua-setup/references/methodology.md — Neovim Lua-specific dimensions, rationale, adaptation rules
  • skills/nvim-lua-setup/references/analysis-checklist.md — how projects are analyzed

Example Questions

"Why selene instead of luacheck?" → Dimension 2. Selene is actively maintained, supports custom std libraries for Neovim globals, better error messages, community standard.

"What's the coverage threshold?" → Dimension 1. 75% default; 50% new; 80% library. Lua coverage tooling (luacov) is less mature.

"Why StyLua for formatting?" → Dimension 2. Fast (written in Rust), opinionated, supports LuaJIT syntax, widely adopted in Neovim ecosystem.

"Why is security analysis limited?" → Dimension 4. No Lua equivalent of bandit/cargo-audit. Uses selene rules + grep patterns.

"How does testing work with Neovim?" → Dimension 1. Test framework detection (plenary, mini.test, busted), headless Neovim execution, minimal_init.lua.

"Why LuaJIT and not Lua 5.4?" → Neovim Lua-Specific Patterns. Neovim embeds LuaJIT (Lua 5.1). All tools must target LuaJIT.

Changes

What this file has done since we first saw it

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.

nvim-lua-explain is a skill published in the GitHub repository ondrasek/cc-plugins (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 69 tokens to every session and 460 once invoked, about $0.0003 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.
