Over-Engineering Detector

VerifiedSafe

Scans codebases for unnecessary complexity, speculative generality, and over-engineered patterns. Useful for spotting premature abstractions, excessive indirection, and unused flexibility, then offers actionable simplifications to reduce technical debt.

Automated summary

Analyzes code to detect unnecessary complexity, speculative generality, and over-engineered solutions.

Strengths

  • Identifies premature abstractions and excessive layers
  • Categorizes issues by severity (critical, warning, info)
  • Provides concrete simplification suggestions with effort estimates

Limitations

  • May produce false positives if business context is not understood
  • Does not replace human review of architectural trade-offs
  • Depends on pattern detection quality (may miss subtle cases)
When to use it

During code review or quality audits to simplify a complex codebase.

When not to use it

When complexity is justified by known future requirements or during rapid prototyping.

Security analysis

Safe
Quality score88/100

The skill only uses read-only tools (Read, Glob, Grep, Task) to analyze code for complexity patterns. It does not execute any code, modify files, or exfiltrate data.

How this analysis is made

Examples

Analyze entire codebase
Analyze the entire codebase for over-engineering, speculative generality, and unnecessary complexity.
Analyze specific directory
detect over-engineering in src/services/
Analyze a file pattern
detect over-engineering in **/*.cs

name: detect-over-engineering description: Detect unnecessary complexity, speculative generality, and over-engineered solutions in code allowed-tools: Read, Glob, Grep, Task argument-hint: "[path-or-pattern]"

Detect Over-Engineering Command

Analyze code to identify unnecessary complexity, speculative generality, and over-engineered solutions.

Usage

/enterprise-architecture:detect-over-engineering [path-or-pattern]

Arguments

  • path-or-pattern (optional): Path to analyze
    • If provided: Analyze the specified path or pattern
    • If omitted: Analyze the entire codebase

Examples

/enterprise-architecture:detect-over-engineering
/enterprise-architecture:detect-over-engineering src/services/
/enterprise-architecture:detect-over-engineering **/*.cs

Workflow

  1. Scan for Complexity Indicators

    • Search for patterns indicating over-engineering
    • Identify abstraction layers
    • Find unused flexibility points
  2. Spawn Over-Engineering Detector Agent Use the over-engineering-detector agent to analyze. The agent detects:

    • Speculative Generality - Abstractions without multiple implementations
    • Premature Abstraction - Complexity before demonstrated need
    • Gold Plating - Features beyond requirements
    • Astronaut Architecture - Excessive layers and indirection
  3. Present Findings Display findings organized by:

    • Critical - Significant complexity with no benefit
    • Warning - Potential over-engineering
    • Info - Minor simplification opportunities

Detection Categories

Speculative Generality

  • Abstract classes with single implementation
  • Interfaces with only one implementer
  • Generic type parameters never varied
  • Configuration options never used
  • Plugin architectures with no plugins

Premature Abstraction

  • Factory patterns for single object creation
  • Strategy patterns with one strategy
  • Excessive dependency injection
  • Over-normalized data structures

Gold Plating

  • Features beyond documented requirements
  • Configurability that's never configured
  • Extensibility points never extended

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/over-engineering-detector-mm8o5243/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/over-engineering-detector-mm8o5243' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/over-engineering-detector-mm8o5243/download' --output '.skill-downloads/over-engineering-detector-mm8o5243/SKILL.md.part' && mv '.skill-downloads/over-engineering-detector-mm8o5243/SKILL.md.part' '.skill-downloads/over-engineering-detector-mm8o5243/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

Tools declared by the author (check availability in your agent): Read, Glob, Grep, Task

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/over-engineering-detector-mm8o5243/SKILL.md' && test -s '.skill-downloads/over-engineering-detector-mm8o5243/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/detect-over-engineering' && cp -R '.skill-downloads/over-engineering-detector-mm8o5243' '.claude/skills/detect-over-engineering'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/over-engineering-detector-mm8o5243'

openskills read 'over-engineering-detector-mm8o5243'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/over-engineering-detector-mm8o5243/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
