detecting-security-vulnerabilities

detecting-security-vulnerabilities is a skill for Claude Code, Codex from WesleySmits/agent-skills. It costs 47 tokens per session (2,195 once invoked), scanned A, original, no licence file.

A code-security review that looks for vulnerabilities and unsafe patterns, including common web threats and exposed secrets.

In plain words
What is it for?
Use it to audit code for issues such as cross-site scripting, SQL injection, leaked credentials, and other OWASP-related risks.
Why use it?
It helps identify security problems before they reach production or become harder to fix.

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

detecting-security-vulnerabilities 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 2mo 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.

Expected in a hook, worth knowing in a rule or an instructions file.

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.
