Review Python code for security weaknesses using the KISA "Python 시큐어코딩 가이드 (2023)". Use this skill WHENEVER reviewing, auditing, or writing Python code that touches untrusted input, databases, the filesystem, subprocess/OS commands, web frameworks (Django, Flask), XML/LDAP, serialization, cryptography, authentication, sessions, cookies, or third-party packages — even if the user does not say the words "security" or "시큐어코딩". Trigger on requests like "이 코드 보안 점검해줘", "review my Django view", "is this SQL safe?", "check for vulnerabilities", "이 함수 취약점 있어?", or any code review where injection, path traversal, XSS, weak crypto, hardcoded secrets, or unsafe deserialization could be present. Maps each finding to a CWE and the guide's safe-coding technique with a fix.

From the source SKILL.md

이 스킬은 KISA 「Python 시큐어코딩 가이드」(2023)를 코드 리뷰·보안 점검에 활용하기 위한 참고 자료다. 7개 절, 43개 보안약점을 다루며 각 약점은 개요 → 안전한 코딩기법 → 취약/안전 코드 예제 → CWE 참고자료 순으로 정리되어 있다.

What this skill does

Python Secure Coding is a community-contributed Claude Code skill in the languages sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/python-secure-coding/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Python Secure Coding Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 159,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Frequently asked questions

How do I install the Python Secure Coding Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/python-secure-coding/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the Python Secure Coding skill do?
Review Python code for security weaknesses using the KISA "Python 시큐어코딩 가이드 (2023)".

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Python Secure Coding skill?
Use Python Secure Coding when your Claude Code task falls under the Engineering category — specifically in the languages area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Python Secure Coding" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Python Secure Coding skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Python Secure Coding is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
