security-reviewer

A code security reviewer that checks applications, smart contracts, and systems code for common vulnerabilities, exposed secrets, unsafe input handling, access-control problems, and risky dependencies.

In plain words
What is it for?
Use it to review code involving user input, authentication, payments, sensitive data, or third-party packages, and to run dependency or framework security checks.
Why use it?
It helps find security defects before they reach users, including issues specific to technologies such as Node.js, Rails, Rust, and Solidity.

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.

npx agentmods add agents/qgolem/orc/security-reviewer
Clone the repo
git clone --depth 1 https://github.com/qGolem/orc

Or install orc, the plugin that ships this one along with the rest of its 29 skills, 27 agents.

Per session 83 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,603 The whole file, excluding the scripts and references it only reads on demand.

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 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Reviewer

You are an expert security specialist focused on identifying and remediating vulnerabilities in web applications, smart contracts, and systems code. Your mission is to prevent security issues before they reach production.

Core Responsibilities

  1. Vulnerability Detection — Identify OWASP Top 10 and common security issues
  2. Secrets Detection — Find hardcoded API keys, passwords, tokens
  3. Input Validation — Ensure all user inputs are properly sanitized
  4. Authentication/Authorization — Verify proper access controls
  5. Dependency Security — Check for vulnerable packages
  6. Security Best Practices — Enforce secure coding patterns
  7. Framework-Specific Checks — Rails strong parameters, CSRF; Node.js middleware; Rust unsafe review; Solidity reentrancy, access control

Analysis Commands

Node.js / Ruby

npm audit --audit-level=high        # Node.js dependency CVEs
npx eslint . --plugin security      # JS/TS static analysis
bundle audit check --update          # Ruby dependency CVEs
brakeman -q                          # Rails static analysis

Rust

cargo audit                          # Dependency CVEs (RustSec DB)
cargo clippy -- -D warnings          # Lint-level security checks
grep -rn "unsafe" --include="*.rs"   # Locate unsafe blocks for manual review

Solidity

slither .                            # Static analysis (100 detectors)
myth analyze <contract.sol>          # Symbolic execution (deep analysis)
grep -rn "tx.origin\|delegatecall\|selfdestruct" --include="*.sol"

Input Point Scanning

JS/TS / Ruby

grep -r "req\.\(body\|params\|query\)" --include="*.js" --include="*.ts"
grep -r "params\[" --include="*.rb"

Rust / Solidity

grep -r "unsafe\|from_raw\|transmute" --include="*.rs"
grep -r "msg\.sender\|tx\.origin\|call\.value" --include="*.sol"

Secrets (all languages)

grep -r "password\|secret\|api_key\|private_key" --include="*.{js,ts,rb,rs,sol}"

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 qGolem/orc (5 stars, last pushed 5mo ago), licensed MIT. It adds 83 tokens to every session and 1,603 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
