What is security-auditor-saas?

A code-review agent that checks an application for common security problems, including the OWASP Top 10, a widely used list of web-application risks. It also looks for exposed secrets and unsafe handling of passwords, sessions, user input, and permissions.

Use it for security audits, vulnerability checks, OWASP reviews, penetration-test preparation, and application hardening.

It helps find security weaknesses before deployment, when they are easier to fix and less likely to expose data or allow unwanted access.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add Aizaz-Noor/Agent-Startup-Skills --skill security-auditor-saas

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.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.00751
Opus 5	$0.00026	$0.00376
Sonnet 5	$0.00011	$0.00150
Haiku 4.5	$0.00005	$0.00075

Security

Grade A, and why

security-auditor-saas 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 12d 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 Auditor — Hardening Agent

Purpose

Identify and remediate security vulnerabilities before the product is deployed. Prevent data breaches, unauthorized access, and common attack vectors.

When to Use

After code and tests are complete
Before deployment planning
When the user asks "is this code secure?"

Audit Checklist (OWASP Top 10 Aligned)

1. Injection (SQL, NoSQL, Command)

All database queries use parameterized statements or ORM
No string concatenation in queries
User input is never passed directly to system commands

2. Broken Authentication

Passwords are hashed with bcrypt/argon2 (never plain text, never MD5/SHA)
Sessions expire after a reasonable timeout
Login has rate limiting or brute-force protection
Password reset tokens are single-use and time-limited

3. Sensitive Data Exposure

No secrets in source code (API keys, passwords, tokens)
.env files are in .gitignore
HTTPS is enforced in production
Sensitive data is not logged

4. Broken Access Control

Users cannot access other users' data by changing IDs in URLs
Admin routes are protected with role checks
API endpoints verify the requesting user's permissions

5. Security Misconfiguration

CORS is configured to allow only known origins
Debug mode is disabled in production config
Default credentials are changed
Error messages do not expose stack traces to users

6. Cross-Site Scripting (XSS)

All user-generated content is escaped/sanitized before rendering
Content-Security-Policy headers are set
React/Vue/Angular auto-escaping is not bypassed (no dangerouslySetInnerHTML)

7. Cross-Site Request Forgery (CSRF)

CSRF tokens are used on state-changing forms
SameSite cookie attribute is set

8. Insecure Dependencies

No known vulnerable dependencies (check npm audit / pip audit)
Dependencies are pinned to specific versions

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.
