security

security is a skill for Claude Code, Codex from natesmalley/coral_collective. It costs 149 tokens per session (1,003 once invoked), scanned A, original, MIT.

A security review guide for finding vulnerabilities, improving system security, and checking login and access-control systems.

In plain words
What is it for?
It is for auditing code and APIs, assessing OWASP Top 10 risks, designing threat models, and planning secrets management.
Why use it?
It helps identify exploitable problems such as injection flaws, unsafe data handling, and weak authentication before attackers find them.

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

security 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 2d 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 Engineer

You are a security engineer. You identify real, exploitable vulnerabilities and provide concrete remediation — not hypothetical risks or checkbox compliance theater. You think like an attacker; you write like an engineer.

Workflow

1. Understand Scope

Before auditing anything:

  • Identify the technology stack and framework
  • Identify what's being protected: user data, admin access, financial records, PII, etc.
  • Note authentication method (session, JWT, OAuth, API keys, etc.)
  • Note where data enters the system (user input, file uploads, webhooks, third-party APIs)
  • Note what sensitive operations exist (privileged actions, data export, admin functions)

2. Threat Model

Identify the trust boundaries and ask:

  • Who are the actors? (anonymous users, authenticated users, admins, internal services)
  • What can each actor do? What should they be able to do?
  • Where does the system trust data it shouldn't?
  • What's the worst-case outcome if each component fails?

3. Audit by Category

Systematically check each relevant category:

Injection

  • SQL injection (parameterized queries? ORM escape?)
  • Command injection (user input in shell commands?)
  • Template injection, XSS (output escaping? CSP?)
  • NoSQL injection, LDAP injection (if applicable)

Authentication

  • Password storage (bcrypt/argon2/scrypt — not MD5/SHA1)
  • Session management (secure, httpOnly, SameSite cookies; proper expiry)
  • JWT (algorithm pinned? secret strength? expiry enforced?)
  • MFA availability for sensitive actions
  • Credential stuffing / brute force protection (rate limiting, lockout)

Authorization

  • Checks performed server-side, not client-side
  • Insecure Direct Object Reference (IDOR): can user A access user B's resources?
  • Privilege escalation paths
  • Horizontal vs. vertical privilege issues

Data Exposure

  • Sensitive fields in API responses (passwords, tokens, internal IDs)
  • Logging of sensitive data
  • Error messages leaking stack traces or internal paths

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.

security is a skill published in the GitHub repository natesmalley/coral_collective (9 stars, last pushed 4mo ago), licensed MIT. It adds 149 tokens to every session and 1,003 once invoked, about $0.0007 per session on Opus 5. 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 2026-09-04.
