What it does

Code Simplifier is an agent skill from mobazha/mobazha-unified. Simplify and refine recently written code for clarity, consistency, and maintainability while preserving all functionality. Use after completing a coding task, fixing a bug, or when the user asks to "simplify", "clean up", "refine", "简化代码", "清理代码", "优化代码", "精简", "重构".

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code simplification. The repository describes itself as: Open-source commerce frontend for storefronts, marketplaces, checkout, and seller management. The licence is MPL-2.0.

When your agent uses it

Asks to simplify
Tasks that involve Code simplification

Example prompts

“simplify”
“clean up”
“refine”
“/code-simplifier”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Identify recently modified code sections (via git diff or user specification)
Analyze for simplification opportunities
Apply project conventions from .cursor/rules/
Verify all functionality remains unchanged
Run pnpm validate:quick to confirm no regressions

What it can do on your machine

Read from SKILL.md and the folder at commit 156c699. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
- pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Code Simplifier loads about 601 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 173 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~71
When it runs · the whole SKILL.md, loaded when a task matches: ~601

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

name: code-simplifier
description: Simplify and refine recently written code for clarity, consistency, and maintainability while preserving all functionality. Use after completing a coding task, fixing a bug, or when the user asks to "simplify", "clean up", "refine", "简化代码", "清理代码", "优化代码", "精简", "重构".

Code Simplifier

对最近修改的代码进行精简优化，提升清晰度和可维护性，不改变行为。

适用场景

实现新功能后
修复 bug 后（特别是添加了多层条件判断时）
重构或性能优化后
用户要求"简化"、"清理"、"优化"代码时

Simplification Rules

DO

Reduce unnecessary complexity and nesting
Eliminate redundant code and abstractions
Improve variable and function names for clarity
Consolidate related logic
Remove obvious comments that describe what code does
Use early returns to reduce nesting
Extract repeated patterns into shared utilities

DON'T

Change what the code does — only how it does it
Use nested ternary operators — prefer if/else or switch
Prioritize fewer lines over readability
Create overly clever solutions hard to understand
Combine too many concerns into single functions
Remove helpful abstractions that improve organization

Process

Identify recently modified code sections (via git diff or user specification)
Analyze for simplification opportunities
Apply project conventions from .cursor/rules/
Verify all functionality remains unchanged
Run pnpm validate:quick to confirm no regressions

Architecture Check

After simplifying, verify code still follows project architecture:

Types in @mobazha/core/types/, not in apps/
Transform functions in @mobazha/core/utils/, not duplicated
Components use hooks for data, not direct API calls
No duplicate business logic across files

Example

typescript

// ❌ Before: nested, hard to follow
function getStatus(order) {
  if (order) {
    if (order.state === 'PENDING') {
      if (order.funded) {
        return 'funded';
      } else {
        return 'awaiting_payment';
      }
    } else if (order.state === 'FULFILLED') {
      return 'shipped';
    } else {
      return 'unknown';
    }
  }
  return 'not_found';
}

// ✅ After: early returns, flat structure
function getStatus(order) {
  if (!order) return 'not_found';

  switch (order.state) {
    case 'PENDING':
      return order.funded ? 'funded' : 'awaiting_payment';
    case 'FULFILLED':
      return 'shipped';
    default:
      return 'unknown';
  }
}
