Security Audit

What Is Security Audit?

The Security Audit skill is a comprehensive security analysis tool designed for modern software development workflows. It integrates seamlessly into the buildwithclaude suite, leveraging the Centinela (QA) agent to systematically review codebases for vulnerabilities and security misconfigurations. Security Audit automates deep inspections across the OWASP Top 10, authentication and authorization logic, data protection mechanisms, dependency vulnerabilities, and hardcoded secrets, providing an actionable report to strengthen application security posture.

By invoking the Security Audit skill, development teams can ensure critical areas of their codebase are regularly scrutinized for common and emerging threats. The skill is flexible, supporting both full-project and scoped audits, making it suitable for continuous integration pipelines as well as targeted security assessments.

Why Use Security Audit?

Security vulnerabilities can have dire consequences, from data breaches to system compromise and regulatory penalties. Manual code reviews, while valuable, are often time-consuming and susceptible to human error, especially under tight release deadlines or in large, fast-moving projects. The Security Audit skill addresses these challenges by:

• Automating Complex Security Checks: Covering a broad spectrum of risks, including those identified in the OWASP Top 10, and scanning for secrets and dependency vulnerabilities.
• Enforcing Security Best Practices: Ensuring that authentication, authorization, and data handling logic are robust and up-to-date with industry standards.
• Delivering Actionable Reports: Outputting clear, organized findings that map vulnerabilities to specific code locations, along with recommendations for remediation.
• Enabling Continuous Security: Supporting frequent, repeatable audits as part of standard development workflows or DevOps pipelines.

With Security Audit, teams can shift security left, identifying and resolving issues early in the development lifecycle, ultimately reducing the cost and impact of security defects.

How to Get Started

To start using the Security Audit skill, ensure you have access to the buildwithclaude agent ecosystem. The skill is invoked via a simple command interface, allowing for both full and selective codebase audits.

Basic Usage

To run a security audit across your entire codebase, simply execute:

/security-audit

This triggers a comprehensive review of all application components.

Scoped Audit

To target specific directories or modules, specify the relevant paths:

/security-audit src/auth/ src/api/

This approach is ideal after changes concentrated in a particular subsystem, such as authentication or API endpoints.

Upon completion, Security Audit generates a detailed markdown report in the docs/reviews/ directory, named according to the audit date (e.g., security-audit-2026-02-23.md).

Key Features

Security Audit offers a robust set of automated checks and reporting capabilities:

1. OWASP Top 10 Systematic

Check

The skill systematically analyzes code for vulnerabilities corresponding to the latest OWASP Top 10 risks, such as:

• A01: Broken Access Control
• A02: Cryptographic Failures
• A03: Injection
• A05: Security Misconfiguration
• A07: Identification and Authentication Failures

For example, if an endpoint lacks proper authorization checks:

@app.route('/admin/delete_user', methods=['POST'])
def delete_user():
    # Missing authentication/authorization check
    user_id = request.form['user_id']
    db.delete_user(user_id)
    return "User deleted"

Security Audit will flag this as a potential A01 (Broken Access Control) issue.

2. Secrets and Credential

Scanning

The skill scans for hardcoded secrets, API keys, tokens, and connection strings within the codebase. For example:

const apiKey = "sk_test_4eC39HqLyjWDarjtT1zdp7dc"; // Hardcoded secret

This line would be surfaced in the audit report under secrets scan results.

3. Dependency

Vulnerabilities

It reviews project dependencies for known vulnerabilities (CVEs) by cross-referencing package manifests (package.json, requirements.txt, etc.) against security advisory databases.

4. Smart Contract

Checks

If Solidity files are detected, Security Audit applies checks for smart contract-specific issues such as reentrancy, integer overflows/underflows, and access control lapses.

5. Structured Reports and

Handoffs

The skill outputs findings categorized by severity, includes a summary verdict (APPROVED or CHANGES REQUIRED), and prepares a handoff for remediation or further review by the development agent.

Best Practices

• Integrate Early and Often: Run Security Audit before releases, after major code changes, or when adding new dependencies.
• Act on Findings Promptly: Address issues flagged in the report, especially those categorized as high or critical severity.
• Scope Audits for Efficiency: Use scoped audits to focus security reviews on high-impact areas or recent changes.
• Maintain Dependency Hygiene: Regularly update dependencies and re-audit to minimize exposure to new vulnerabilities.
• Review and Remove Secrets: Ensure that no secrets or credentials are committed to the codebase.

Important Notes

• Security Audit automates many critical checks but should complement, not replace, manual code reviews and penetration testing.
• The accuracy of findings depends on codebase accessibility and the completeness of the scanned areas.
• For audits involving sensitive or proprietary code, ensure that the buildwithclaude suite and the Centinela agent are properly secured and comply with organizational policies.
• Reports are written to the docs/reviews/ directory; ensure this location is monitored and access-controlled.
• For optimal results, follow up on the audit’s recommendations and re-run the audit after implementing changes.
