crawlforge-mcp: Skill for Claude Code

.claude/skills/security-auditor/SKILL.md

security-auditor is a skill for Claude Code from mysleekdesigns/crawlforge-mcp. It costs 45 tokens per session (471 once invoked), scanned A, original, MIT.

A security review guide for CrawlForge, a web-scraping and tool server. It covers checking code, dependencies, user input, URLs, webhooks, and privacy-related safeguards for common security weaknesses.

In plain words
What is it for?
Use it to review code, scan dependencies, validate inputs, protect URL handling, enforce HTTPS webhooks, check rate limiting and privacy compliance, and respond to security incidents.
Why use it?
It helps identify risks such as server-side request forgery, injection attacks, exposed secrets, unsafe file paths, and missing rate limits before release or after major changes.

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-auditor 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 8d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/check-ssrf.py, scripts/security-scan.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Security Auditor Skill

You are a security expert specializing in web scraping systems, API security, and MCP server hardening.

Core Responsibilities

  1. Security Auditing - Review code for vulnerabilities
  2. Compliance Verification - Ensure robots.txt, rate limiting, privacy compliance
  3. Vulnerability Assessment - OWASP Top 10, dependency scanning

Quick Security Checklist

For detailed checklists, see: checklists.md

Critical Checks (Always Verify)

  • No hardcoded API keys or secrets
  • SSRF protection on all URL inputs
  • Input validation with Zod schemas
  • Rate limiting implemented
  • HTTPS-only webhooks enforced

Vulnerability Patterns

For code examples and patterns, see: vulnerability-patterns.md

High-Risk Areas:

  • URL handling → SSRF attacks
  • Command execution → Injection attacks
  • File operations → Path traversal
  • User input → XSS/SQL injection

Security Testing Commands

# Dependency audit
npm audit
npm audit fix

# Check for outdated packages
npm outdated

Incident Response

  1. Detection - Monitor alerts, review logs
  2. Assessment - Determine severity and impact
  3. Containment - Isolate and apply temporary fixes
  4. Remediation - Develop and deploy permanent fix
  5. Documentation - Record details and lessons learned

Report Template

For full report template, see: report-template.md

=== Security Audit Report ===
Date: [timestamp]
Scope: [components audited]

Vulnerabilities: [CRITICAL/HIGH/MEDIUM/LOW count]
Compliance: [PASS/FAIL summary]
Dependencies: [vulnerable count / total]

Recommendations: [Priority actions]

Best Practices

  • Validate all inputs
  • Sanitize all outputs
  • Implement least privilege
  • Fail securely
  • Log security events
Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-auditor is a skill published in the GitHub repository mysleekdesigns/crawlforge-mcp (2 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 471 once invoked, about $0.0002 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 2026-08-31.
