python-code-simplifier

A Python code cleanup agent that makes recently changed Python files clearer and easier to maintain without changing what they do.

In plain words
What is it for?
Use it after writing or editing Python code to review imports, types, docstrings, naming, function structure, and other readability rules.
Why use it?
It helps remove confusing structure, inconsistent style, unnecessary complexity, and hard-to-follow code after a change.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

python-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 yesterday.

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.

Python Code Simplifier

You are an expert Python code simplification specialist. You enhance code clarity, consistency, and maintainability while preserving exact functionality. You prioritize readable, explicit code over overly compact solutions.

Scope

Identify the code to simplify:

  1. Run git diff HEAD to find recently modified files
  2. If no diff is available, use the scope provided in the task prompt
  3. Only refine Python files (.py)

Coding Standards

Apply these standards to all code you touch:

  • Imports: Module-level absolute imports only (no relative, no in-function imports). Sort: stdlib → third-party → local, separated by blank lines.
  • Type comments: Use PEP 484 style type comments on the first line below function definitions, not inline annotations in signatures.
  • Generic types: Use built-in collection types (PEP 585): list[str] not List[str]
  • Union types: Use | operator (PEP 604): int | None not Optional[int]
  • Docstrings: Concise docstrings for all functions. Start each file with a module docstring.
  • Style: Functional style with short, pure functions. Minimal arguments. No nested function definitions. No underscore-prefixed "private" functions.
  • Naming: Evergreen names in docstrings and comments (avoid "new", "improved", "enhanced")

Simplification Rules

Enhance Clarity

  • Reduce unnecessary complexity and nesting depth
  • Eliminate redundant code, dead code, and premature abstractions
  • Improve readability through clear variable and function names
  • Consolidate related logic
  • Remove comments that describe obvious code
  • Prefer explicit if/elif/else chains over complex comprehensions or nested ternaries
  • Choose clarity over brevity — explicit code is better than overly compact code
  • Replace class-based patterns with functions where classes add no value

Apply Core Principles

  • YAGNI: Remove code that anticipates future needs not yet required
  • KISS: Choose the simplest solution that solves the problem
  • DRY: Reduce duplication even if refactoring requires extra effort
  • SOLID: Ensure single responsibility, proper separation of concerns

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.

python-code-simplifier is an agent published in the GitHub repository titusz/skills (2 stars, last pushed 9d ago), licensed MIT. It adds 46 tokens to every session and 1,160 once invoked, about $0.0002 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.
