code-simplifier

code-simplifier is a command for Claude Code from CloudAI-X/claude-workflow-v2. It costs 19 tokens per session (727 once invoked), scanned A, original, MIT.

A post-implementation code review that looks for simpler ways to organize recently changed code without changing what it does. It checks for duplication, dead code, unnecessary abstractions, and overly complex logic.

In plain words
What is it for?
Use it after implementation to inspect recent changes, remove unused code, simplify conditionals, reduce unnecessary wrappers, and split overly long functions when appropriate.
Why use it?
It helps reduce maintenance effort and make code easier to understand after a feature or fix has been added. The review keeps behavior unchanged while identifying structure that can be reduced or clarified.

About the project

Project Starter is a workflow plugin that equips coding agents with specialized subagents, reusable skills, commands, hooks, and output styles for software projects. It is for developers who want structured assistance with tasks such as planning, debugging, code review, security, and automation across several coding-agent platforms. Catalogue add-ons are components of its own workflow.

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-simplifier 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 27d 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.

Code Simplifier

Simplify code after implementation. Find ways to make code cleaner and simpler without changing behavior.

Philosophy

  • Simpler is better
  • Less code = fewer bugs
  • Clarity over cleverness
  • Don't change behavior, only structure
  • Delete code when possible

Phase 1: Identify Recent Changes

git diff HEAD~1 --name-only
git log -1 --stat
git diff HEAD~1

Phase 2: Analyze for Simplification

Look for these patterns:

1. Duplicate Code

  • Repeated logic that can be extracted
  • Similar functions that can be merged
  • Copy-pasted code with minor variations

2. Over-Engineering

  • Abstractions used only once
  • Unnecessary wrapper functions
  • Over-parameterized functions (too many options)
  • Premature generalization

3. Dead Code

  • Unused variables
  • Unreachable branches
  • Commented-out code
  • Unused imports/dependencies

4. Complex Conditionals

  • Nested if-else chains (flatten with early returns)
  • Complex boolean expressions (extract to named variables)
  • Guard clauses that can be simplified

5. Long Functions

  • Functions > 20 lines (consider splitting)
  • Multiple responsibilities (single responsibility)
  • Too many parameters (use objects)

6. Unnecessary Complexity

  • Try-catch around code that can't fail
  • Null checks on values that can't be null
  • Defensive code for impossible cases

Phase 3: Propose Simplifications

For each finding, present:

### Simplification: [Short description]

**Location**: `file:line`
**Type**: [Duplicate/Over-engineering/Dead code/etc.]

**Current** (X lines):
```[lang]
[code block]
```

**Simplified** (Y lines):
```[lang]
[code block]
```

**Benefit**: [Why this is better]
**Risk**: Low - behavior unchanged

Phase 4: Apply Simplifications

After user approval:

  1. Make one change at a time
  2. Run tests after each change
  3. Commit with clear message: refactor: simplify [description]
  4. Move to next simplification

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.

code-simplifier is a command published in the GitHub repository CloudAI-X/claude-workflow-v2 (1,420 stars, last pushed 23d ago), licensed MIT. It adds 19 tokens to every session and 727 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
