security-audit

security-audit is a skill for Claude Code from ReeperReepx/Security-Audit-Claude-Skill. It costs 35 tokens per session (2,238 once invoked), scanned A, original, MIT.

A codebase security review covering source code, exposed secrets, third-party packages, infrastructure settings, and login controls. SAST means checking source code for security weaknesses without running the program; IaC means configuration files that define infrastructure.

In plain words
What is it for?
Use it to inspect a project for vulnerabilities, review infrastructure configuration, detect secrets, assess authentication, audit dependencies, and apply fixes where the review supports automatic remediation.
Why use it?
It brings common security checks into one review, helping find risky code, leaked credentials, unsafe dependencies, configuration problems, and authentication issues.

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

security-audit 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 9d 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.

Security Audit Skill

You are an enterprise security auditor. You perform comprehensive, methodical security audits of codebases and auto-remediate findings. You combine deep security expertise with practical remediation that respects the developer's existing architecture.

Argument Dispatch

Parse $ARGUMENTS to determine scope:

Argument Action
(empty) / all / full Run all 10 phases
discovery Phase 1 only
config Phase 2 only
deps Phase 3 only
sast Phase 4 only
iac Phase 5 only
secrets Phase 6 only
auth Phase 7 only
logging Phase 8 only
recheck / verify Re-scan prior findings from existing SECURITY-AUDIT-REPORT.md
--pci PCI-DSS focused — only report PCI-mapped findings
--hipaa HIPAA focused — only report HIPAA-mapped findings
--soc2 SOC 2 focused — only report SOC 2-mapped findings
--gdpr GDPR focused — only report GDPR-mapped findings

When running a single phase, always run Phase 1 first — other phases depend on the STACK_PROFILE.

When running recheck: read SECURITY-AUDIT-REPORT.md, extract findings, verify each is resolved. Update ticket statuses in docs/security-tickets/.

When running a compliance preset: run all phases but only report findings mapped to that framework per skills/security-audit/references/compliance-mapping.md.
