code-security-audit

code-security-audit is a skill for Claude Code, Codex from Azzygoatcoder/agent-useful-skills. It costs 95 tokens per session (2,001 once invoked), scanned A, original, MIT.

A codebase security audit that checks software for vulnerabilities and produces a structured report with severity levels and suggested fixes.

In plain words
What is it for?
Auditing a repository, scanning quickly for risks, reviewing security changes, and checking fixes after an earlier audit.
Why use it?
It helps find security problems systematically instead of relying on one broad review or guesswork. It can also verify whether reported issues were fixed.

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

code-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 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.

Code Security Audit

Overview

Systematic security audit of any codebase using parallel domain exploration. Launch independent review agents across three security domains simultaneously, then synthesize findings into a structured audit report with severity ratings and concrete remediation steps.

Core principle: Coverage through parallelization. Three focused agents catch more than one broad agent — each domain has different grep patterns, different mental models, and different blind spots.

场景判定(先定深度,再走流程)

场景 触发 深度 产出 流程
快速风险扫描 "/audit quick" / "快扫一眼" L1 一页风险概览(不看全文) Phase 1 单 agent + 摘要,跳过 Self-Check
全面审计(默认) "audit this repo" / "安全审计" / "/audit" L2-L3 完整 SECURITY_AUDIT.md Phase 1-3 全流程
增量重审 "/reaudit" / "检查修复" 变更文件 重审段 + 状态更新 Phase 4
单 PR / 单文件 "review this PR" / "看下这个改动" 代码评审 委托 code-review,不进安全审计
快速修复 "/security-fix" / "修漏洞" 按 P1-P4 批量修复 security-fix-skill

默认是全面审计。用户要求"快扫/quick"才降级 L1;"修漏洞/再审计"分别走 security-fix / reaudit。场景不清时按全面审计走,深度宁高勿低。

Slash Commands

Command Action
/audit Full security audit — explore → verify → report (Phase 1–3)
/reaudit Verify previous audit fixes were applied (Phase 4)
/reaudit mark-fixed <ID> Lightweight: mark a finding as fixed (update status annotation only, no file read)
/reaudit mark-deferred <ID> Mark a finding as structurally deferred
/reaudit status Show current fix progress (count by status from annotations)
/code-security-audit Same as /audit (canonical name)

When to Use

Trigger when the user asks to:

  • Audit a repository or codebase for security issues
  • Perform a security review or vulnerability assessment
  • Check if security fixes were properly applied (re-audit)
  • Find vulnerabilities before a release or deployment

Do NOT use for:

  • Reviewing a single PR diff (use /security-review or manual review)
  • Checking one specific function for bugs (use systematic-debugging)
  • General code review for style/architecture (use /code-review)

Files

What ships with it

3 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.

code-security-audit is a skill published in the GitHub repository Azzygoatcoder/agent-useful-skills (4 stars, last pushed 6d ago), licensed MIT. It adds 95 tokens to every session and 2,001 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
