webscan

A command that scans websites for security weaknesses using Nuclei, Nikto, and an AI assessment tool. Nuclei checks known vulnerability patterns, while Nikto checks common server misconfigurations and files.

In plain words
What is it for?
Use it to scan a web target for template-matched vulnerabilities, server problems, vulnerable paths, and technology-specific issues.
Why use it?
It brings several kinds of web checks together and combines duplicate results into a severity-sorted set of findings.

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

webscan 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 2d 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.

Storage Policy: ALL output files MUST be saved in the project directory. NEVER write to /tmp/ or any system temporary directory.

Web Vulnerability Scan

Target: $ARGUMENTS

Execute multi-engine web vulnerability scanning using Hexstrike MCP tools.

Step 1: Load Tools

Use ToolSearch to load:

  • nuclei_scan — template-based vulnerability scanning
  • nikto_scan — web server misconfiguration scanning
  • ai_vulnerability_assessment — AI-powered vulnerability assessment

Step 2: Nuclei Scan

Run nuclei_scan against the target with:

  • Severity filter: critical, high, medium
  • Rate limiting appropriate for the target (lower for WAF-protected targets)
  • Include technology-specific templates if tech stack is known

Step 3: Nikto Scan

Run nikto_scan for server misconfiguration, default files, and known vulnerable paths.

Step 4: AI Vulnerability Assessment

Run ai_vulnerability_assessment on the target for intelligent vulnerability detection that adapts to the target's technology stack and responses.

Step 5: Results

Consolidate findings from all three engines, deduplicate, and present sorted by severity:

  • CRITICAL: Immediate exploitation possible
  • HIGH: Significant impact, likely exploitable
  • MEDIUM: Moderate impact or requires specific conditions
  • LOW/INFO: Informational findings

Save consolidated report to webscan-{target}.md in the project directory. Flag any findings that warrant immediate manual investigation.

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.

webscan is a command published in the GitHub repository ogrodev/fsociety (20 stars, last pushed 5mo ago), licensed MIT. It adds 17 tokens to every session and 371 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
