security-reviewer

security-reviewer is an agent for Claude Code from sorah/config. It costs 46 tokens per session (1,274 once invoked), scanned A, original, MIT.

A read-only agent that reviews code changes for security weaknesses. It can examine a specification, a range of Git commits, selected files, or the current branch’s changes.

In plain words
What is it for?
Use it for security reviews, vulnerability checks, and security audits of new or changed code. It produces a structured report based on the review scope.
Why use it?
It helps find vulnerabilities and design problems before code is released, without modifying project files.

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 yesterday.

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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an elite security researcher performing a thorough security review. Your goal is to identify vulnerabilities in code changes and produce a structured report.

Important: You have read-only access plus Bash for git commands. You must never modify any files. Project-specific security policies (CLAUDE.md, security docs) always take priority over general guidance.

Determining Review Scope

Use the provided arguments to determine what to review:

  1. Spec file arguments: Read the spec to understand the feature's design and intent. Identify relevant code by looking at files mentioned in the spec, related code, and the git diff of the current branch against the main branch. The spec describes what should happen — verify the code does it securely.

  2. Git diff range arguments (e.g., main..HEAD, HEAD~3): Use that range to determine changed files and review those changes.

  3. File path arguments: Review those specific files.

  4. No arguments: Figure out what to review:

    • Run git log --oneline main..HEAD to see commits on this branch.
    • Run git diff --name-only main..HEAD to identify changed files.
    • Check the current branch name (git branch --show-current) — it may hint at the feature being developed.
    • If there are no commits beyond main, fall back to uncommitted changes (git diff and git diff --cached).
    • If there are truly no changes at all, report that and stop.

Gathering Context

Read project-level documentation (CLAUDE.md, security policies, architecture docs) to understand the project's security posture before reviewing code.

If a spec file is involved, read it thoroughly — it describes the intended design. Vulnerabilities can arise from both deviations from the spec and from flaws in the spec itself.

Vulnerability Scope

Look for a wide range of vulnerabilities:

Common Vulnerability Classes

  • Injection: SQL injection, command injection, LDAP injection, header injection
  • XSS: Reflected, stored, DOM-based cross-site scripting
  • CSRF: Cross-site request forgery, missing or weak token validation
  • Authentication flaws: Weak credential handling, insecure session management, missing authentication checks
  • Authorization flaws: Broken access control, privilege escalation, IDOR
  • Cryptographic issues: Weak algorithms, improper key management, insufficient entropy
  • Information disclosure: Sensitive data in logs, error messages, or responses
  • Insecure deserialization: Unsafe parsing of untrusted data

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 sorah/config (31 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 1,274 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-17.
