security-review

security-review is a command for Claude Code from CrashBytes/claude-role-skills. It costs 8 tokens per session (529 once invoked), scanned A, original, Apache-2.0.

A security-focused review of a file or code changes. It checks common application risks, including unsafe input handling, weak authentication, exposed sensitive data, access-control errors, insecure settings, and vulnerable dependencies.

In plain words
What is it for?
Use it to review a file, a Git change set, staged changes, or recent changes for vulnerabilities and missing security controls.
Why use it?
It helps find security problems before code is merged or released. It focuses review attention on risks that ordinary code review may miss, such as secret exposure, injection, and unauthorized access.

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-review 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 2mo 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.

Arguments

Target to review: $ARGUMENTS

Context

Recent changes: !git diff --stat HEAD~1 2>/dev/null || echo "No git context"

Workflow

  1. Identify review scope

    • If a file path is provided, read it
    • If a git ref is provided, get the diff
    • If no argument, review staged or recent changes

  2. Check OWASP Top 10

    • Injection: SQL, NoSQL, OS command, LDAP injection via unsanitized inputs
    • Broken Auth: Hardcoded credentials, weak session management, missing MFA hooks
    • Sensitive Data: Secrets in code, unencrypted PII, excessive logging of sensitive data
    • XXE / Deserialization: Unsafe XML parsing, insecure deserialization
    • Broken Access Control: Missing authorization checks, IDOR vulnerabilities, path traversal
    • Misconfig: Debug mode enabled, default credentials, verbose error messages in production
    • XSS: Unescaped user input in HTML output, innerHTML usage, dangerouslySetInnerHTML
    • Insecure Dependencies: Known CVEs in dependencies (check package.json/requirements.txt)
    • Insufficient Logging: Missing audit trails for auth events and data access
    • SSRF: Unvalidated URLs in server-side requests

  3. Check secure coding patterns

    • Input validation at trust boundaries
    • Output encoding for the correct context (HTML, URL, JS, CSS)
    • Parameterized queries (no string concatenation in SQL)
    • Proper error handling (no stack traces to users)
    • Secure defaults (deny by default, least privilege)
    • Secrets management (env vars or vault, not hardcoded)

  4. Check dependency security

    • If package.json exists: npm audit findings
    • If requirements.txt exists: known vulnerabilities
    • Flag any pinned versions with known CVEs

  5. Output

    • Issues grouped by severity: Critical / High / Medium / Low / Info
    • Each issue: file, line, vulnerability type, code snippet, fix recommendation
    • Summary: total issues by severity, overall risk assessment

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.
