clean-code-principles

clean-code-principles is a skill for Claude Code, Codex from AsyrafHussin/agent-skills. It costs 67 tokens per session (1,744 once invoked), scanned A, original, MIT.

A reference guide to common software design principles, including SOLID, avoiding repetition, keeping solutions simple, and using design patterns.

In plain words
What is it for?
Reviewing architecture, checking code quality, refactoring, and discussing how software should be organised.
Why use it?
It gives developers shared rules for making code easier to understand, maintain, and change.

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

clean-code-principles 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 6d 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.

Clean Code Principles

Fundamental software design principles, SOLID, design patterns, and clean code practices. Language-agnostic guidelines for writing maintainable, scalable software.

When to Apply

Reference these guidelines when:

  • Designing new features or systems
  • Reviewing code architecture
  • Refactoring existing code
  • Discussing design decisions
  • Improving code quality

Rule Categories by Priority

Priority Category Impact Prefix
1 SOLID Principles CRITICAL solid-
2 Core Principles CRITICAL core-
3 Design Patterns HIGH pattern-
4 Code Organization HIGH org-
5 Naming & Readability MEDIUM name-
6 Functions & Methods MEDIUM func-
7 Comments & Documentation LOW doc-

Quick Reference

1. SOLID Principles (CRITICAL)

  • solid-srp - Single Responsibility Principle
  • solid-ocp - Open/Closed Principle
  • solid-lsp - Liskov Substitution Principle
  • solid-isp - Interface Segregation Principle
  • solid-dip - Dependency Inversion Principle

2. Core Principles (CRITICAL)

  • core-dry - Don't Repeat Yourself
  • core-kiss - Keep It Simple, Stupid
  • core-yagni - You Aren't Gonna Need It
  • core-separation-of-concerns - Separate different responsibilities
  • core-composition-over-inheritance - Favor composition
  • core-law-of-demeter - Principle of least knowledge
  • core-fail-fast - Detect and report errors early
  • core-encapsulation - Hide implementation details

3. Design Patterns (HIGH)

  • pattern-factory - Factory pattern for object creation
  • pattern-strategy - Strategy pattern for algorithms
  • pattern-repository - Repository pattern for data access
  • pattern-decorator - Decorator pattern for behavior extension
  • pattern-observer - Observer pattern for event handling
  • pattern-adapter - Adapter pattern for interface conversion
  • pattern-facade - Facade pattern for simplified interfaces
  • pattern-dependency-injection - DI for loose coupling

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.

clean-code-principles is a skill published in the GitHub repository AsyrafHussin/agent-skills (72 stars, last pushed 9d ago), licensed MIT. It adds 67 tokens to every session and 1,744 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 2026-08-30.
