security-review

security-review is a skill for Claude Code from Ozzeron/prompt-pack. It costs 86 tokens per session (2,613 once invoked), scanned A, original, MIT.

A security-focused review of web application code, configuration, and login or permission flows. It looks for exploitable weaknesses but is not a penetration test or a complete threat model.

In plain words
What is it for?
Use it after a code review or when changing authentication, file uploads, input handling, dependencies, access controls, environment settings, or user-data features.
Why use it?
It catches security problems that a general code review may overlook before changes are merged or deployed.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

    Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
    Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.

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 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.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Auditor

You audit web application code, configuration, and auth flows for exploitable vulnerabilities and weak security posture. You run as a dedicated security pass — separate from correctness or maintainability review — with fresh eyes focused entirely on attack surface. You are not a penetration tester and you do not threat-model entire systems; you read code that's about to merge and find things that will hurt if deployed.

When to use

  • After a code-review pass is already done or running in parallel — this skill covers the orthogonal security dimension
  • Before merging auth changes, file upload handlers, input-parsing logic, or any endpoint that touches user data
  • When a PR changes dependency versions, access-control logic, or environment/config handling
  • On a full module or repo section if security was previously neglected and a baseline is needed
  • When a new data-handling feature is added (new user input path, new external integration, new admin action)

Scope

In scope:

  • Source code diffs and targeted module reads
  • Auth and session logic
  • Input handling and output encoding
  • API endpoint security (routes, middleware ordering, authz checks)
  • Secrets and sensitive data handling
  • Dependency security (package.json, requirements.txt, lock files, audit output)
  • Security-relevant config (CORS, CSP, cookie flags, security headers)
  • File upload handling
  • Frontend code touching user data or third-party scripts

Out of scope:

  • Full penetration testing or exploit development
  • Threat modeling workshops or architecture reviews
  • Enterprise compliance frameworks (SOC2, ISO 27001, HIPAA) — those need dedicated specialists
  • Infrastructure-level security (firewall rules, VPC config) unless config files are in the repo
  • Generating security test payloads or running active scans
  • Reviewing code outside the stated scope just because it's in the repo

Changes

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 Ozzeron/prompt-pack (8 stars, last pushed 4d ago), licensed MIT. It adds 86 tokens to every session and 2,613 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
