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 5.1 | $0.00000 | $0.02957 |
| Opus 5.5 | $0.00000 | $0.01183 |
| Sonnet 5.5 | $0.00000 | $0.00591 |
| Haiku 4.5 | $0.00000 | $0.00296 |
Grade A, and why
python-authentication-failures 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 1mo 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.
This is a copy
100% identical to python-authentication-failures — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 338 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Python Identification and Authentication Failures Standards (OWASP A07:2021)
This rule enforces security best practices to prevent identification and authentication failures in Python applications, as defined in OWASP Top 10:2021-A07.
actions:
-
type: enforce conditions:
Pattern 1: Weak password validation
- pattern: "password\s*=\s*['"][^'"]{1,7}['"]|min_length\s*=\s*[1-7]" message: "Weak password policy detected. Passwords should be at least 8 characters long and include complexity requirements."
Pattern 2: Hardcoded credentials
- pattern: "(username|user|login|password|passwd|pwd|secret|api_key|apikey|token)\s*=\s*['"][^'"]+['"]" message: "Hardcoded credentials detected. Store sensitive credentials in environment variables or a secure vault."
Pattern 3: Missing password hashing
- pattern: "password\s*=\srequest\.form\[\'password\'\]|password\s=\s*request\.POST\.get\(\'password\'\)" message: "Storing or comparing plain text passwords detected. Always hash passwords before storage or comparison."
Pattern 4: Insecure password hashing
- pattern: "hashlib\.md5\(|hashlib\.sha1\(|hashlib\.sha224\(" message: "Insecure hashing algorithm detected. Use strong hashing algorithms like bcrypt, Argon2, or PBKDF2."
Pattern 5: Missing brute force protection
- pattern: "@app\.route\(['"]\/(login|signin|authenticate)['"]" message: "Authentication endpoint detected without rate limiting or brute force protection. Implement account lockout or rate limiting."
Pattern 6: Insecure session management
- pattern: "session\[\'user_id\'\]\s*=|session\[\'authenticated\'\]\s*=\s*True" message: "Session management detected. Ensure proper session security with secure cookies, proper expiration, and rotation."
Pattern 7: Missing CSRF protection in authentication
- pattern: "form\s*=\sFlaskForm|class\s+\w+Form\(\sFlaskForm\s*\)|class\s+\w+Form\(\sForm\s\)" message: "Form handling detected. Ensure CSRF protection is enabled for all authentication forms."
Pattern 8: Insecure remember me functionality
- pattern: "remember_me|remember_token|stay_logged_in" message: "Remember me functionality detected. Ensure secure implementation with proper expiration and refresh mechanisms."
Pattern 9: Insecure password reset
- pattern: "@app\.route\(['"]\/(reset-password|forgot-password|recover)['"]" message: "Password reset functionality detected. Ensure secure implementation with time-limited tokens and proper user verification."
Pattern 10: Missing multi-factor authentication
- pattern: "def\s+login|def\s+authenticate|def\s+signin" message: "Authentication function detected. Consider implementing multi-factor authentication for sensitive operations."
Pattern 11: Insecure direct object reference in user management
- pattern: "User\.objects\.get\(id=|User\.query\.get\(|get_user_by_id\(" message: "Direct user lookup detected. Ensure proper authorization checks before accessing user data."
Pattern 12: Insecure JWT implementation
- pattern: "jwt\.encode\(|jwt\.decode\(" message: "JWT usage detected. Ensure proper signing, validation, expiration, and refresh mechanisms for JWTs."
Pattern 13: Missing secure flag in cookies
- pattern: "set_cookie\([^,]+,[^,]+,[^,]secure=False|set_cookie\([^,]+,[^,]+(?!,\ssecure=True)" message: "Cookie setting without secure flag detected. Set secure=True for all authentication cookies."
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.

python-authentication-failures is a cursor rule published in the GitHub repository abderrahimghazali/cursor-rules (2 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,957 tokens. A static security scan graded it A with 0 findings. It is 100% identical to python-authentication-failures, differing in 0 lines, and is treated as a copy.
