UnityCodeMCPServer: Skill for Claude Code

.agents/skills/creating-python-scripts/SKILL.md

creating-python-scripts is a skill for Claude Code, Codex from Signal-Loop/UnityCodeMCPServer. It costs 42 tokens per session (1,036 once invoked), scanned A, original, MIT.

Guidance for creating or editing one standalone Python script, with its package requirements recorded inside the file when needed. UV is the Python tool used to run such scripts and manage those inline requirements.

In plain words
What is it for?
Use it for a single-file Python utility, command-line helper, prototype, or small automation.
Why use it?
It keeps small utilities and one-off automations easy to run and avoids turning them into unnecessary multi-file projects.

This is Signal-Loop/UnityCodeMCPServer's own configuration. It tells Claude Code and Codex how to work on UnityCodeMCPServer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything UnityCodeMCPServer configures →

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

creating-python-scripts scanned grade A with 1 finding 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 2mo 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.

Creating Single-File UV Python Scripts

Overview

Use this skill to keep Python script work script-shaped.

The default outcome is one .py file that can be run with uv. If third-party packages are needed, declare them inside the script with inline metadata instead of creating separate dependency files.

When To Use

Use this skill when the user asks for:

  • a Python script
  • a small Python utility
  • a one-off automation
  • a standalone CLI helper
  • a quick prototype that does not need to become a package

Do not use this skill when the user explicitly asks for:

  • a multi-file Python project
  • a package or library
  • a framework app
  • a repository scaffold with pyproject.toml

If the user asks for a script but the requested architecture clearly requires multiple files, say that the single-file constraint conflicts with the requested design and ask whether to keep the script constraint or expand to a project.

Core Rules

  1. Produce a single .py file.
  2. Do not create helper modules, packages, requirements.txt, or pyproject.toml for script tasks.
  3. Use uv commands when showing how to run the script.
  4. If the script needs third-party packages, use inline metadata in the script.
  5. If the script only uses the standard library, omit the dependency metadata block.
  6. If you are asked to execute, test, or verify the script, do it with uv run rather than raw python.

Required Workflow

1. Confirm the work is really script-sized

Prefer a single-file script when the task is automation, data processing, API calls, file transformation, or a small CLI.

If the request starts drifting toward a package, service, or app structure, stop and surface the tradeoff instead of quietly creating extra files.

2. Keep everything in one file

Put imports, configuration constants, helper functions, CLI parsing, and the main entry point in the same file.

Avoid splitting code into separate modules unless the user explicitly relaxes the single-file requirement.

creating-python-scripts is a skill published in the GitHub repository Signal-Loop/UnityCodeMCPServer (20 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 1,036 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
