asvs-requirements

asvs-requirements is a skill for Claude Code, Codex from Zate/cc-plugins. It costs 38 tokens per session (4,330 once invoked), scanned A, original, MIT.

A reference guide to the OWASP Application Security Verification Standard (ASVS) 5.0, a checklist for checking whether web applications are built securely. It organizes security requirements into 17 areas and three levels of audit depth.

In plain words
What is it for?
Planning audit scope, choosing a verification level, defining checks for security-auditing agents, and linking findings to specific ASVS requirements in reports.
Why use it?
It gives security audits a consistent set of requirements instead of leaving auditors to decide what to check from scratch.

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

asvs-requirements 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 4d 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.

ASVS 5.0 Requirements

Structured access to OWASP Application Security Verification Standard (ASVS) 5.0 requirements for security auditing.

When to Use This Skill

  • Planning security audits - To understand which chapters apply to the project
  • Scoping audit depth - To select appropriate verification level (L1/L2/L3)
  • Building auditor agents - To define specific checks for each domain
  • Mapping findings - To reference ASVS requirements in audit reports

When NOT to Use This Skill

  • Quick vulnerability checks - Use vulnerability-patterns skill instead
  • Remediation guidance - Use remediation-library skill instead
  • Non-ASVS audits - Use industry compliance auditors directly

ASVS Verification Levels

Level Name Applicability Depth
L1 Opportunistic All applications Minimum baseline
L2 Standard Most applications Recommended
L3 Advanced High-value/critical apps Maximum rigor

Mapping to Audit Modes:

  • Quick Scan → L1 requirements only
  • Standard Audit → L1 + L2 requirements
  • Comprehensive Audit → L1 + L2 + L3 requirements

Chapter Overview

Chapter Name Requirements Primary Focus
V1 Encoding & Sanitization 28 Injection prevention
V2 Validation & Business Logic 15 Input validation
V3 Web Frontend Security 32 Browser security
V4 API & Web Service 17 API security
V5 File Handling 14 File security
V6 Authentication 44 Identity verification
V7 Session Management 18 Session security
V8 Authorization 11 Access control

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.
