security-scan

security-scan is a skill for Claude Code, Codex from drvoss/everything-copilot-cli. It costs 38 tokens per session (3,145 once invoked), scanned A, original, MIT.

A code and dependency security checker that looks for common application vulnerabilities, including patterns from the OWASP Top 10, and audits packages your project uses.

In plain words
What is it for?
Use it for release checks, dependency audits, periodic reviews, incident follow-ups, and targeted fixes to high-impact findings.
Why use it?
It helps find security problems before they reach production, especially after adding dependencies or when you are new to a codebase.

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-scan scanned grade A with 2 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- wrapper-prefixed commands such as `env ...`, `sudo ...`, `watch ...`, `ionice ...`, and

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 319 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Scan

When to Use

  • Before releasing a new version or deploying to production
  • After adding new dependencies
  • During periodic security reviews
  • When onboarding to an unfamiliar codebase
  • After a security incident to check for similar vulnerabilities

When NOT to Use

Instead of security-scan Use
PR-diff-only security review pr-security-review
Agent / MCP / LLM risk review agent-owasp-check
Strategic threat-model audit security-audit or threat-model-analyst

Prerequisites

  • Access to the project source code and dependency manifests
  • Package manager CLI available (npm, pip, go, etc.)
  • Understanding of the application's architecture (web, API, CLI, etc.)

Workflow

0. Choose the operating mode

This skill can run in three distinct modes without becoming a separate skill:

  1. Secure-by-default implementation — when writing new code or refactoring risky paths, identify the stack first, load any matching security references, and keep safe defaults in mind while implementing.
  2. Passive detection during the current task — while you are already reading or editing files, call out only high-impact violations of the loaded guidance. This is not a background watcher; it applies only to the files you are actively handling.
  3. Explicit security report — when the user asks for a review or report, produce a prioritized findings list with IDs, severity, and concrete file:line references.

0a. Load stack-specific security references

Before scanning deeply, identify the language and primary framework in scope. If the shared ../../../references/security-scan/ directory contains a matching file, read it first and pair it with the shared repository checklist at ../../../references/security-checklist.md.

Suggested lookup order:

  1. framework-specific reference such as ../../../references/security-scan/javascript-typescript-general-security.md when the codebase is JS/TS-heavy
  2. ../../../references/security-scan/python-general-security.md when the codebase is Python-heavy
  3. ../../../references/security-scan/rust.md when the codebase is Rust-heavy
  4. the shared repository checklist when no stack-specific note exists

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-scan is a skill published in the GitHub repository drvoss/everything-copilot-cli (45 stars, last pushed 8d ago), licensed MIT. It adds 38 tokens to every session and 3,145 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
