A security-audit workflow for source code, dependencies, configuration files, and infrastructure.

In plain words
What is it for?
Use it to scan projects for issues such as SQL injection, cross-site scripting, command injection, path traversal, hardcoded credentials, and known CVEs.
Why use it?
It helps find common vulnerabilities, exposed secrets, unsafe authentication or authorization, and dependencies with known security problems.

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

skill-security-auditor scanned grade A with 1 finding 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/scan_project.py, scripts/scan_secrets.py), 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.

Security Auditor Guide

Overview

This guide covers security auditing workflows for source code, dependencies, and configurations. For detailed vulnerability patterns and detection rules, see references/vulnerability-patterns.md. For secrets detection patterns, see references/secrets-patterns.md.

Quick Start

Run the bundled scan script against a project directory:

python scripts/scan_project.py /path/to/project

This performs a lightweight scan for common issues: hardcoded secrets, dangerous function calls, and insecure patterns. For deeper analysis, follow the workflows below.

Testing the scripts

python scripts/scan_project.py /path/to/some/project --format text
python scripts/scan_secrets.py /path/to/some/project --format text

Audit Workflow

1. Reconnaissance

Before auditing, understand the project:

# Identify languages, frameworks, and entry points
find . -type f -name "*.py" -o -name "*.js" -o -name "*.ts" -o -name "*.go" -o -name "*.java" | head -20
cat package.json pyproject.toml requirements.txt go.mod pom.xml 2>/dev/null

Key questions:

  • What frameworks are used? (Express, Django, Flask, Spring, etc.)
  • Where are the entry points? (routes, controllers, API handlers)
  • How is authentication handled?
  • What external services are called?
  • Is user input accepted? Where?

2. Secrets Detection

Scan for hardcoded credentials, API keys, and tokens. See references/secrets-patterns.md for the full pattern list.

python scripts/scan_secrets.py /path/to/project

Common patterns to check:

  • API keys and tokens in source files
  • Database connection strings with embedded passwords
  • Private keys or certificates committed to the repo
  • .env files or config files with plaintext secrets
  • Secrets in CI/CD configuration files

3. Vulnerability Scanning

A05 Security Misconfiguration Debug mode, default credentials, verbose errors
A06 Vulnerable Components Outdated dependencies with known CVEs
A07 Auth Failures Weak passwords, missing MFA, session issues
A08 Data Integrity Failures Insecure deserialization, unsigned updates

What ships with it

5 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.

skill-security-auditor is a skill published in the GitHub repository eigent-ai/eigent (15,622 stars, last pushed today), licensed Apache-2.0. It adds 114 tokens to every session and 1,652 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
