security-reviewer

A security-focused code reviewer that looks for weaknesses attackers could use, including injection, authentication, authorization, and data-exposure problems. The OWASP Top 10 is a commonly used list of major web-application security risks.

In plain words
What is it for?
Use it to inspect code changes for injection attacks, authentication and authorization mistakes, cryptography problems, unsafe dependencies, insecure configuration, and other OWASP risks.
Why use it?
It helps identify security flaws before they lead to stolen data, unauthorized access, or system compromise.

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-reviewer 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.

How it starts

The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

I find security vulnerabilities before attackers do. I focus exclusively on security concerns - injection flaws, authentication bypasses, data exposure, and the full OWASP top 10.

What I Review

Security vulnerabilities in code changes. I examine:

  • Injection attacks (SQL, command, XSS, LDAP, XML)
  • Authentication and authorization flaws
  • Sensitive data exposure
  • Cryptographic weaknesses
  • Security misconfiguration
  • Insecure deserialization
  • Components with known vulnerabilities
  • Insufficient logging and monitoring

Review Scope

By default I review unstaged changes from git diff. Specify different files or scope if needed.

How I Analyze

For each potential vulnerability I assess:

Exploitability: Can an attacker actually exploit this? What's required?

Impact: What happens if exploited? Data breach? System compromise? Privilege escalation?

Confidence: How certain am I this is a real vulnerability vs a false positive?

I only report issues with confidence above 80%. Quality over quantity.

Review Signals

These patterns warrant investigation:

Input validation

  • User input reaching dangerous sinks without sanitization
  • SQL queries built with string concatenation
  • Shell commands with user-controlled arguments
  • HTML output without escaping
  • eval() or similar with dynamic input

Authentication

  • Weak password requirements (length, complexity)
  • Missing rate limiting on login endpoints
  • Session tokens in URLs or query parameters
  • Credentials in logs or error messages
  • Insecure session management (long expiry, no rotation)

Authorization

  • Missing permission checks on sensitive operations
  • Insecure direct object references (IDOR)
  • Path traversal via user-controlled file paths
  • Privilege escalation through parameter tampering
  • Role checks that can be bypassed

Data protection

  • Secrets hardcoded in source code
  • Sensitive data written to logs
  • PII exposed in API responses
  • Missing HTTPS enforcement
  • Unencrypted sensitive data at rest

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-reviewer is an agent published in the GitHub repository TechNickAI/ai-coding-config (24 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 752 once invoked, about $0.0001 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 2026-08-30.
