What it does
Code Quality Standards is an agent skill from Goldziher/ai-rulez. Concrete code-quality thresholds and anti-patterns: 120-char lines, max 20 cyclomatic complexity, max 4 nesting levels, max 50 lines per function, no magic numbers, no global state, composition over inheritance, no bare except, rule-of-three before extracting an abstraction, delete dead code instead of commenting it out. Load when writing a new function or module, reviewing a diff for quality, refactoring a long or deeply nested function, or deciding whether to extract shared logic.
Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Code quality, State management and Refactoring. The repository describes itself as: One source of truth for AI assistant configs: 14 built-in presets (Claude, Cursor, Copilot, Codex, Gemini, Xum, …), full-parity custom presets, and distributable plugin bundles… The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit c269bcb. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Code Quality Standards loads about 486 tokens when it runs. Until then it costs about 128 tokens; SKILL.md has 200 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.

- code-quality-standards
- description
- Concrete code-quality thresholds and anti-patterns: 120-char lines, max 20 cyclomatic complexity, max 4 nesting levels, max 50 lines per function, no magic numbers, no global state, composition over inheritance, no bare except, rule-of-three before extracting an abstraction, delete dead code instead of commenting it out. Load when writing a new function or module, reviewing a diff for quality, refactoring a long or deeply nested function, or deciding whether to extract shared logic.
Readability
- Max 120 character line width.
- Prefer explicit code over clever tricks — if it needs a comment to explain what it does, rewrite it.
- No abbreviations in public API names (
contextnotctx,repositorynotrepo). - Keep functions short and focused on a single responsibility.
Complexity limits
Max 20 cyclomatic complexity per function, max 4 levels of nesting depth, max 50 lines per function. Use early returns to flatten conditionals. Break complex functions into well-named helpers that each do one thing.
Anti-patterns
- No magic numbers — use named constants.
- No global state — use dependency injection.
- No inheritance for code reuse — prefer composition.
- No bare exception handlers — catch specific types.
- No mocking internal services — use real objects for integration tests.
- No blocking I/O in async code paths — keep async paths fully async.
Duplication
Extract shared logic after the third repetition, not before. Three similar lines are better than a premature abstraction. When extracting, ensure the shared code has a single reason to change — if two callers would evolve the logic differently, keep them separate. Premature abstraction creates worse coupling than duplication.
Dead code
Remove dead code instead of commenting it out. Version control preserves history; commented-out code creates confusion and maintenance burden.

Can I use Code Quality Standards in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Goldziher/ai-rulez --skill code-quality-standards -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/code-quality-standards, .gemini/skills/code-quality-standards, .github/skills/code-quality-standards and .opencode/skills/code-quality-standards in your project.
What does Code Quality Standards need to run?
SKILL.md names no scripts, command-line tools or credentials: Code Quality Standards is instructions for the agent only.
Does Code Quality Standards access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
