agent-security-scanning

agent-security-scanning is a skill for Claude Code from itallstartedwithaidea/agent-skills. It costs 20 tokens per session (1,716 once invoked), scanned C, original, MIT.

A security scanner for code produced by AI agents. It checks the code, its dependencies, and agent-specific risks such as prompt injection and unsafe tool use.

In plain words
What is it for?
It helps review generated code for issues such as injection, cross-site scripting, server-side request forgery, known dependency CVEs, prompt injection, tool misuse, and possible data exfiltration.
Why use it?
It helps catch vulnerabilities that normal functional tests may miss, including injection flaws, risky dependencies, and unsafe patterns such as dynamic SQL, eval, or unchecked deserialization.

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 C, and why

agent-security-scanning scanned grade C with 3 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 7d 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.

Agent Security Scanning

Part of Agent Skills™ by googleadsagent.ai™

Description

Agent Security Scanning detects vulnerabilities in AI-generated code before it reaches production. The agent applies OWASP Top 10 for LLM Applications, scans for known CVEs in dependencies, identifies prompt injection vectors, and flags insecure patterns specific to agent-generated code—such as unsanitized dynamic SQL, eval() usage, and unvalidated deserialization.

AI code generators produce code that "works" but frequently contains security vulnerabilities invisible to functional testing. Studies show that AI-generated code contains exploitable vulnerabilities at higher rates than human-written code, particularly in input validation, authentication, and cryptographic operations. This skill applies security analysis specifically calibrated for the patterns that AI agents produce.

The scanning pipeline covers three layers: static analysis of generated code (injection, XSS, SSRF), dependency vulnerability scanning (CVE database matching), and agent-specific threat modeling (prompt injection, tool misuse, data exfiltration through tool calls). Each finding includes a severity rating, CWE classification, and a concrete remediation with code example.

Use When

  • Reviewing AI-generated code before committing or deploying
  • Scanning dependencies for known CVEs after npm install or pip install
  • Auditing agent tool call patterns for potential misuse
  • Implementing security gates in CI/CD pipelines
  • The user requests security review, vulnerability scan, or penetration testing
  • Building applications that handle user input, authentication, or payments

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.

agent-security-scanning is a skill published in the GitHub repository itallstartedwithaidea/agent-skills (37 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 1,716 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 3 findings (downloads and executes remote code, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
