code-simplifier

code-simplifier is an agent for Claude Code from NYTC69/review-loop. It costs 77 tokens per session (543 once invoked), scanned A, original, Apache-2.0.

An agent that rewrites recently changed code to make it clearer, more consistent, and easier to maintain without changing its behavior.

In plain words
What is it for?
Use it after coding tasks to simplify functions and structure, apply the project's coding conventions, and preserve existing outputs and behavior.
Why use it?
It removes unnecessary complexity and style inconsistencies that can make code harder to understand or update.

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 11d 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 coding standards in the project's CLAUDE.md (or equivalent) and the conventions visible in the surrounding code: module and import style, function style, type annotations, error handling, and naming.

  3. 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
    • 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
  4. 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
  5. Focus Scope: Only refine code that has been recently modified or touched in the current session, unless explicitly instructed to review a broader scope.

Document only significant changes that affect understanding.

Your goal is code in the requested scope that is simpler and easier to maintain, with its behavior unchanged.

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 an agent published in the GitHub repository NYTC69/review-loop (3 stars, last pushed yesterday), licensed Apache-2.0. It adds 77 tokens to every session and 543 once invoked, about $0.0003 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 2026-08-31.
