security-review

security-review is a skill for Claude Code, Codex from airvalona/antigravity-like-claude-code. It costs 54 tokens per session (409 once invoked), scanned A, original, MIT.

A security-focused code scanner for a Git diff, selected code, or an entire codebase. It checks for risks such as injection, exposed credentials, broken access controls, unsafe input handling, and insecure configuration.

In plain words
What is it for?
Use it to audit changed files, a folder, or a whole repository. It reports each finding with a severity, location, risk explanation, and suggested fix.
Why use it?
It focuses the review on vulnerabilities instead of general code quality. It helps identify security problems before they reach production.

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 9d 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.

What it actually says

/security-review — Vulnerability Scan

Port of Claude Code's /security-review. Security-only, unlike code-review which is general-purpose.

Arguments

  • /security-review — scan the current uncommitted diff.
  • /security-review <target> — scan a specific file, folder, or the whole repo.

Checklist

  1. Injection: SQL injection, command injection, path traversal, template injection, unsafe eval/exec
  2. Secrets: hardcoded API keys, tokens, passwords, credentials committed to the diff or already present in tracked files
  3. Auth & access control: missing auth checks on new endpoints/handlers, broken object-level authorization, privilege escalation paths
  4. Input handling: unvalidated/unsanitized user input reaching sensitive sinks (file system, network, shell, DB)
  5. Dependencies: newly added packages with known CVEs or from untrusted sources (flag for the user to verify — don't fabricate CVE numbers)
  6. Config: overly permissive CORS, disabled TLS verification, debug mode left on, insecure default credentials

Reporting

For each finding: severity (Critical / High / Medium / Low), file:line, the specific risk, and a concrete fix — not just "sanitize this input" but the actual sanitization approach for that language/framework.

Do not attempt to actually exploit anything found — report only. Do not write or suggest working exploit code, even for demonstration purposes.

Notes

If nothing significant is found, say so plainly rather than manufacturing low-value nits to seem thorough.

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.
