claude-security-audit: Instructions file for Claude Code

CLAUDE.md

claude-security-audit CLAUDE.md is an instructions file for Claude Code from afiqiqmal/claude-security-audit. It costs 828 tokens per session, scanned A, original, MIT.

A set of instructions for a Claude Code security-audit command that examines code and reports findings using security standards such as OWASP and CWE.

In plain words
What is it for?
Use it for full, quick, gray-box or focused audits of authentication, APIs or configuration, including file paths, line numbers, vulnerable code and standards mappings.
Why use it?
It gives audits a fixed structure, severity labels and evidence requirements, making findings easier to review and compare. It also separates reporting from code changes unless a fix option is requested.

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is afiqiqmal/claude-security-audit's own configuration. It tells Claude Code how to work on claude-security-audit 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 claude-security-audit 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

claude-security-audit CLAUDE.md 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.

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.

CLAUDE.md

Project

Claude Code slash command for white-box and gray-box security auditing. Maps findings to OWASP Top 10:2025, CWE, NIST CSF 2.0, SANS/CWE Top 25, OWASP ASVS 5.0, PCI DSS 4.0.1, MITRE ATT&CK, SOC 2 and ISO 27001:2022. Includes security hotspots, code smells and framework-specific checks.

Conventions

  • No em-dashes. Use - (space-hyphen-space) instead
  • No comma before "and" (no Oxford comma)
  • No AI jargon: avoid "leverage", "utilize", "cutting-edge"
  • Every finding must have OWASP, CWE ID and NIST CSF 2.0 mapping (other compliance frameworks where applicable, skip extras with --lite)
  • Every finding must include exact file path, line number and vulnerable code
  • Code fixes are only included when user passes --fix flag
  • Severity indicators: 🔴 CRITICAL, 🟠 HIGH, 🟡 MEDIUM, 🟢 LOW, 🔵 INFO
  • Reports save to ./security-audit-report.md (and .pdf if a converter is installed)

Modes

  • full (default) - All phases (1-5)
  • quick - CRITICAL and HIGH only (phases 1-2)
  • gray - Gray-box testing only (phases 1, 3)
  • focus:auth / focus:api / focus:config - Deep dives (phases 1, 2, 4)
  • diff / diff:BRANCH - Git-changed files only (phases 0, 1, 2, 4)
  • recheck:PATH - Re-audit specific files/directories (phases 1, 2, 4)
  • triage - Interactive triage of existing report
  • phase:1 through phase:5 - Single phase execution
  • --fix - Include remediation code blocks
  • --lite - OWASP + CWE + NIST only (reduces token usage)
  • --fail-on critical|high|medium - CI gating with exit summary
  • --format sarif|json - Structured output (SARIF v2.1.0 or JSON)
  • --update-baseline - Write finding fingerprints for future comparison
  • --diff-report path - Compare with previous report
  • --pack name - Load compliance packs (hipaa, gdpr, fintech, saas-multi-tenant, soc2, education)

Structure

  • .claude/commands/security-audit.md - The slash command (entry point)
  • references/attack-vectors.md - Detailed checklists per attack category
  • references/nist-csf-mapping.md - NIST CSF 2.0 mapping tables
  • references/compliance-mapping.md - CWE, SANS Top 25, ASVS, PCI DSS, ATT&CK, SOC 2, ISO 27001 mapping
  • references/custom-template.md - Template for custom security checks
  • references/frameworks/ - Framework-specific checklists (Laravel, Next.js, FastAPI, Express, Django, Rails, Spring Boot, ASP.NET Core, Go, Flask, Nuxt.js, SvelteKit)
  • references/features-extended.md - Baseline, SARIF/JSON, report diff and triage specs
  • references/packs/ - Compliance packs (HIPAA, GDPR, fintech, SaaS multi-tenant, SOC 2, Education)
  • security-audit-guidelines.md - Severity ratings, modes and conventions
  • install.sh - Installs command and references to ~/.claude/

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.
