code-smells-expert

code-smells-expert is a skill for Claude Code, Codex from jggomez/expert-ai-developer-skills. It costs 92 tokens per session (1,060 once invoked), scanned A, original, Apache-2.0.

Analyzes source code to identify, classify, and diagnose architectural design flaws known as "Code Smells" and technical debt. Use this skill when requested to perform a technical audit, evaluate code quality, look for SOLID violations (especially SRP and OCP), or identify reasons why code is difficult to maintain or…

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

code-smells-expert 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 today.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/detect_smells.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Code Smells Expert Skill

Overview

This skill performs structured technical debt audits to identify, classify, and diagnose design flaws known as "Code Smells". It acts as a Senior Software Architect and Technical Debt Diagnostician, grounding assessments in the Fowler/Beck taxonomy. Its primary mission is pure diagnosis and impact analysis, explaining why structural flaws impede maintainability, extensibility, and testability before any refactoring begins.

When to Use

Trigger Scenarios

  • Conducting architectural code reviews and technical audits.
  • Identifying violations of SOLID principles (especially Single Responsibility and Open/Closed).
  • Preparing for refactoring by cataloging structural friction points and antipatterns.
  • Explaining why a component is difficult to test, understand, or extend.

When NOT to Use

  • Applying code changes or executing refactoring: Route to refactoring-code-expert.
  • Security and vulnerability scanning: Route to security-audit.
  • CPU and memory performance profiling: Route to performance-scalability.
  • Writing new unit or integration tests: Route to test-driven-development.

Process

Phase 1: Automated Static Analysis

Execute the AST-based smell detection script on specific files or target directories:

python3 ./skills/code-smells-expert/scripts/detect_smells.py [optional_path_to_file_or_directory]

The tool flags threshold violations for method length (>30 lines), class size (>300 lines), parameter count (>4), and nested conditional depth.

Phase 2: Structural Review via Fowler/Beck Taxonomy

Review classes, methods, and dependencies against the five major smell categories:

  1. Bloaters: Long Method, Large Class, Primitive Obsession, Long Parameter List, Data Clumps.
  2. Object-Oriented Abusers: Switch Statements / Type checks violating OCP, Refused Bequest, Alternative Classes with Different Interfaces.
  3. Change Preventers: Divergent Change (one class modified for multiple unrelated reasons), Shotgun Surgery (single change requires modifying many classes).
  4. Dispensables: Comments explaining what rather than why, Duplicate Code, Dead Code, Speculative Generality.
  5. Couplers: Feature Envy (method accesses another class's data more than its own), Inappropriate Intimacy, Message Chains.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
