fire-vuln-scan

fire-vuln-scan is a command for Claude Code from ThierryN/fire-flow. It costs 18 tokens per session (4,119 once invoked), scanned A, original, MIT.

An application security scanner that uses AI reasoning to look for common weaknesses in a codebase, including injection flaws, cross-site scripting, and broken authentication. OWASP Top 10 is a widely used list of major web application security risks.

In plain words
What is it for?
Use it to scan a file or project, inspect findings, request suggested fix code, and save a security report.
Why use it?
It can identify security problems that simple pattern-matching scanners may overlook and can focus on server-side or selected vulnerability areas.

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

fire-vuln-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 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.

/fire-vuln-scan

AI-powered application vulnerability scanner — find what regex-based tools miss


Purpose

Scan application codebases for OWASP Top 10 vulnerabilities using Claude's code reasoning — not pattern matching. Inspired by Anthropic's Claude Code Security (launched 2026-02-20), which found 500+ bugs that humans missed for decades.

What this is: Application security scanner (finds SQL injection, XSS, broken auth in YOUR code) What this is NOT: Agent security scanner (that's /fire-security-scan — protects Claude from prompt injection)

fire-vuln-scan is a command published in the GitHub repository ThierryN/fire-flow (77 stars, last pushed 28d ago), licensed MIT. It adds 18 tokens to every session and 4,119 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
