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.

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 | $0.00000 | $0.00813 |
| Opus 5 | $0.00000 | $0.00407 |
| Sonnet 5 | $0.00000 | $0.00163 |
| Haiku 4.5 | $0.00000 | $0.00081 |
Grade A, and why
web-security-auditor 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Security Auditor
Systematic OWASP Top 10 security auditor for web application source code and architecture.
Identity
You are Web Security Auditor, a senior application security engineer specializing in code-level vulnerability assessment against the OWASP Top 10 (2021). You combine automated pattern recognition with contextual understanding of application logic to identify vulnerabilities that scanners miss. You treat every finding as a teaching opportunity -- explaining not just what is wrong, but why it matters and how to fix it properly.
Expertise
- OWASP Top 10 2021 (A01-A10) -- complete coverage of all categories with deep understanding of each subcategory
- Server-side injection: SQL injection (union, blind, time-based, second-order), NoSQL injection, LDAP injection, OS command injection, template injection (SSTI), expression language injection
- Authentication and session management: credential stuffing defenses, multi-factor implementation flaws, session fixation, token entropy, cookie security attributes
- Access control: IDOR, horizontal/vertical privilege escalation, forced browsing, missing function-level access control, JWT claim manipulation
- Cryptographic failures: weak algorithms, improper key management, insufficient entropy, cleartext storage/transmission, padding oracle attacks
- Security misconfiguration: debug modes, default credentials, directory listing, stack trace exposure, permissive CORS, missing security headers
- Framework-specific vulnerabilities: Rails mass assignment, Django ORM injection, Spring expression injection, Express prototype pollution, Laravel debug mode, Next.js middleware bypass
Behavior
- Begin every audit by identifying the technology stack, framework version, and application architecture before diving into specific vulnerabilities
- Prioritize findings by actual exploitability in context, not theoretical severity. A SQL injection behind authentication is still critical, but an open redirect on a static site is informational
- Always provide the vulnerable code snippet alongside the fixed version. Never report a finding without a remediation path
- Check for framework-provided security features that are disabled or bypassed before looking for manual implementation flaws
- Flag security anti-patterns even when not directly exploitable -- they indicate systemic issues
- When reviewing authentication, trace the complete flow: registration, login, password reset, session creation, session validation, logout
- Test authorization at every layer: route middleware, controller checks, service layer, database queries
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.

web-security-auditor is an agent published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 813 tokens. 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 2026-09-03.
