code-simplification

code-simplification is a skill for Claude Code, Codex from vignesh2027/AI-AGENT-SKILLS. It costs 17 tokens per session (613 once invoked), scanned A, original, MIT.

A guide for making code easier to understand and change while keeping its behavior the same. It distinguishes unnecessary complexity from complexity required by the problem.

In plain words
What is it for?
Use it during code reviews, when functions are hard to test, when adding features requires too much context, or in a simplify workflow.
Why use it?
It reduces dead code, needless abstractions, and overly complicated functions without removing code whose purpose has not been understood. The approach first checks why existing code is there.

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-simplification 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 4d 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.

Overview

Every line of code is a liability. Complexity that serves no purpose makes systems harder to understand, harder to test, and harder to change. This skill removes accidental complexity while preserving intentional complexity and essential behavior.

When to Use

  • When a PR review reveals unnecessarily complex code
  • When a function is hard to test because it does too many things
  • When adding a feature to existing code requires understanding too much context
  • As part of the /simplify workflow

Process

Step 1: Understand before you remove (Chesterton's Fence)

Before removing any code that seems unnecessary: understand why it was written. If you don't know why a fence exists, don't remove it. Find out first.

Step 2: Identify the complexity types

  • Accidental complexity: complexity from poor implementation choices
  • Essential complexity: complexity inherent to the problem domain

Only remove accidental complexity. Essential complexity cannot be removed — only managed.

Step 3: Look for these simplification opportunities

Dead code: Code that is never executed. Remove it (git remembers it).

Premature abstraction: Abstractions that are more complex than the thing they abstract. Inline them.

Unnecessary indirection: Function A calls function B which calls function C and each is 5 lines. Collapse them.

Redundant comments: Comments that say what the code already says. Delete them. Keep comments that explain WHY.

Magic numbers: Replace if (retries > 3) with if (retries > MAX_RETRIES).

Over-engineered error handling: 10 levels of nested try/catch for a case that can't happen. Simplify.

Duplicate logic: The same logic in 3 places. Extract to one place.

Step 4: Simplify in small steps

One simplification at a time. Run tests after each step.

Step 5: Verify behavior is unchanged

The test suite must pass. If there are no tests, write tests for the behavior you're simplifying before you simplify 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.

code-simplification is a skill published in the GitHub repository vignesh2027/AI-AGENT-SKILLS (2 stars, last pushed 6d ago), licensed MIT. It adds 17 tokens to every session and 613 once invoked, about $0.0001 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 2026-08-31.
