security-review

security-review is a skill for Claude Code from bostonaholic/rpikit. It costs 41 tokens per session (1,376 once invoked), scanned A, original, MIT.

A method for reviewing code changes for security risks, such as unsafe input handling, database access problems, or weak authentication.

In plain words
What is it for?
Use it to review implementation diffs, new dependencies, APIs, configuration, file operations, and other high-risk changes.
Why use it?
It focuses attention on newly changed code, where vulnerabilities can be introduced before a change is committed.

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 12d 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 Review Methodology

Review implementation changes for security vulnerabilities and risks.

Purpose

This skill provides methodology for reviewing code changes introduced during implementation. Unlike full codebase audits, this focuses on the delta - what was added or modified - to catch security issues before they're committed.

Review Scope

Determine Changed Files

Identify what was modified during implementation:

  • Files created or modified in the current session
  • Changes visible in git diff (staged and unstaged)
  • New dependencies added

Categorize by Risk Level

High-Risk Changes (require thorough review):

  • Authentication/authorization logic
  • Input handling and validation
  • Database queries and data access
  • API endpoints and route handlers
  • Cryptographic operations
  • File system operations
  • External service integrations
  • Configuration changes

Medium-Risk Changes:

  • Business logic with data transformations
  • Error handling and logging
  • Session management
  • Form processing

Low-Risk Changes:

  • UI/styling changes
  • Documentation
  • Test files (unless testing security features)

Security Checklist

Input Validation

  • All user inputs validated before use
  • Validation happens server-side (not just client)
  • Input length limits enforced
  • Type checking performed
  • Allowlists preferred over denylists

Injection Prevention

  • SQL queries use parameterized statements
  • No string concatenation in queries
  • Shell commands avoid user input (or properly escaped)
  • No eval() or dynamic code execution with user data
  • Template rendering escapes output by default

Authentication & Authorization

  • Authentication required for protected routes
  • Authorization checks at each access point
  • No hardcoded credentials
  • Secrets loaded from environment/config (not code)
  • Session tokens properly validated

Data Protection

  • Sensitive data not logged
  • PII handled according to requirements
  • Passwords hashed with strong algorithms (bcrypt, argon2)
  • Encryption used for sensitive data at rest
  • HTTPS enforced for data in transit

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-review is a skill published in the GitHub repository bostonaholic/rpikit (20 stars, last pushed 5d ago), licensed MIT. It adds 41 tokens to every session and 1,376 once invoked, about $0.0002 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.
