tsq-security

tsq-security is a skill for Claude Code from sonature-lab/timsquad. It costs 67 tokens per session (655 once invoked), scanned A, original, MIT.

A set of software security review guidelines based on the OWASP Top 10, a commonly used list of major web-application risks. It covers areas such as unsafe input, exposed secrets, weak access controls, and cross-site scripting.

In plain words
What is it for?
Use it when reviewing authentication, permissions, APIs, user input, dependencies, shell scripts, and code that may contain secret keys.
Why use it?
It helps identify and prevent common security mistakes before they expose data or let attackers misuse the application.

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

tsq-security 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check-secrets.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Security Guidelines (OWASP Top 10)

보안 취약점을 사전에 방지하고 체계적으로 검토한다.

Philosophy

  • 모든 외부 입력은 검증한다 (Trust Nothing)
  • 시크릿은 코드에 절대 포함하지 않는다
  • 보안은 사후 점검이 아닌 설계 단계부터 고려한다

Contract

  • Trigger: 보안 관련 코드 변경 (인증, 권한, 입력 처리, API)
  • Input: 변경 코드 + 보안 컨텍스트
  • Output: OWASP 준수 코드 + 시크릿 미노출
  • Error: 취약점 발견 시 즉시 수정 + 보안 로그
  • Dependencies: 없음

Protocol

  1. 위협 모델링: 공격 표면 식별
  2. 구현: OWASP 가이드 준수 코딩
  3. OWASP 체크: Top 10 항목별 검증
  4. 시크릿 스캔: 하드코딩 시크릿 탐색

Verification

Check Command Pass Criteria
셸 스크립트 shellcheck *.sh exit code 0
의존성 취약점 npm audit critical 0건
시크릿 스캔 bash scripts/check-secrets.sh 0건
입력 검증 수동 검증 모든 외부 입력 Zod 검증

Resources

Priority Type Resource Description
CRITICAL rule owasp-examples 취약점별 Bad/Good 코드 예시
HIGH script check-secrets 하드코딩 시크릿 자동 스캔

Quick Rules

OWASP Top 10 핵심

# 취약점 방어
1 Injection Parameterized Query, ORM
2 Broken Auth bcrypt(12+), 강력한 패스워드
3 Data Exposure DTO로 민감 정보 제외
5 Access Control authenticate + authorize
7 XSS textContent, innerHTML 금지

시크릿 관리

  • 금지: 하드코딩 (const apiKey = 'sk-...')
  • 필수: 환경변수 (process.env.API_KEY)
Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
