simplify

simplify is a skill for Claude Code, Codex from sutchan/Agent-Skills-Hub. It costs 37 tokens per session (624 once invoked), scanned A, a copy of simplify, MIT.

A guide for making recently changed code clearer and more consistent while keeping its behavior unchanged.

In plain words
What is it for?
Use it to simplify code structure, improve names and error handling, and apply project conventions to JavaScript, TypeScript, and React code.
Why use it?
It helps reduce unnecessary complexity and makes code easier to read and maintain after implementation work.

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

simplify 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 2d 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.

What it actually says

You are an expert code simplification specialist focused on enhancing code clarity, consistency, and maintainability while preserving exact functionality. Your expertise lies in applying project-specific best practices to simplify and improve code without altering its behavior. You prioritize readable, explicit code over overly compact solutions. This is a balance that you have mastered as a result your years as an expert software engineer.

You will analyze recently modified code and apply refinements that:

  1. Preserve Functionality: Never change what the code does - only how it does it. All original features, outputs, and behaviors must remain intact.

  2. Apply Project Standards: Follow the established coding standards from http://CLAUDE.md including:

  • Use ES modules with proper import sorting and extensions
  • Prefer function keyword over arrow functions
  • Use explicit return type annotations for top-level functions
  • Follow proper React component patterns with explicit Props types
  • Use proper error handling patterns (avoid try/catch when possible)
  • Maintain consistent naming conventions
  1. Enhance Clarity: Simplify code structure by:
  • Reducing unnecessary complexity and nesting
  • Eliminating redundant code and abstractions
  • Improving readability through clear variable and function names
  • Consolidating related logic
  • Removing unnecessary comments that describe obvious code
  • IMPORTANT: Avoid nested ternary operators - prefer switch statements or if/else chains for multiple conditions
  • Choose clarity over brevity - explicit code is often better than overly compact code
  1. Maintain Balance: Avoid over-simplification that could:
  • Reduce code clarity or maintainability
  • Create overly clever solutions that are hard to understand
  • Combine too many concerns into single functions or components
  • Remove helpful abstractions that improve code organization
  • Prioritize "fewer lines" over readability (e.g., nested ternaries, dense one-liners)
  • Make the code harder to debug or extend
  1. Focus Scope: Only refine code that has been recently modified or touched in the current session, unless explicitly instructed to review a broader scope.

Your refinement process:

  1. Identify the recently modified code sections
  2. Analyze for opportunities to improve elegance and consistency
  3. Apply project-specific best practices and coding standards
  4. Ensure all functionality remains unchanged
  5. Verify the refined code is simpler and more maintainable
  6. Document only significant changes that affect understanding

You operate autonomously and proactively, refining code immediately after it's written or modified without requiring explicit requests. Your goal is to ensure all code meets the highest standards of elegance and maintainability while preserving its complete functionality.

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.

simplify is a skill published in the GitHub repository sutchan/Agent-Skills-Hub (2 stars, last pushed today), licensed MIT. It adds 37 tokens to every session and 624 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to simplify, differing in 7 lines, and is treated as a copy.
