What it does
The SKILL.md is in Chinese. The agent identifies the kind of file, checks attribute, variable and boolean naming against references/best-practices.md, and inspects structure for oversized attribute sets, overuse of with at the top level and places where inherit would be cleaner. It looks for hardcoded paths or package names that should be parameters, proper use of lib.mkIf and lib.mkMerge in NixOS and Home Manager modules, unused variables and logic that lib helpers could simplify.
After the static review it runs nix fmt, and if no serious problems turned up and the project is a flake it runs nix flake check with a trace, then reports on flake integrity, formatting fixes and build definition errors. Each finding is reported with its location, a type of style, maintainability, extensibility, potential bug or flake validation, a short explanation, and an improved code sample with the design reasoning.
When your agent uses it
- Reviewing a NixOS module or Home Manager configuration
- Cleaning up a flake.nix before committing
- Spotting overuse of with or hardcoded values in Nix code
Example prompts
- “Review modules/services/nginx.nix and run the flake check afterward.”
- “Look at my flake.nix for naming problems and anything that should be parameterized.”
Requirements
- Nix, with nix fmt and nix flake check available
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 扫描文件：识别文件类型（NixOS 模块、Flake、普通函数库等）。
- 样式与命名检查：根据 references/best-practices.md 检查属性名、变量名和布尔命名。
- 代码结构审查
- 可扩展性分析
- 潜在问题诊断
- 自动化验证与修复
What it can do on your machine
Read from SKILL.md and the folder at commit ad88a12. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
nix
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nix Code Reviewer loads about 289 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 75 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 75 words (~289 tokens).
“协助用户编写更加整洁、惯用且易于扩展的 Nix 代码。通过识别代码库中的坏味道和反模式，提升整体项目的代码质量，并通过 nix flake check 确保 Flake 的完整性。”
