Scanning Tools

Security Scanning Tools

Overview

This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/scanning-tools from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

Security Scanning Tools

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Purpose, Prerequisites, Outputs and Deliverables, Constraints and Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: Master essential security scanning tools for network discovery, vulnerability assessment, web application testing, wireless security, and compliance validation. This skill covers tool selection, configuration, and....
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Comprehensive CVE detection
2. Compliance checks (PCI-DSS, HIPAA, CIS)
3. Custom scan templates
4. Credentialed scanning for deeper analysis
5. Regular plugin updates
6. Set browser proxy to 127.0.0.1:8080
7. Import Burp CA certificate for HTTPS

Phase 8: Scanning Methodology

Structured scanning approach:

1. Planning

   • Define scope and objectives
   • Obtain proper authorization
   • Select appropriate tools

2. Discovery

   • Host discovery (Nmap ping sweep)
   • Port scanning
   • Service enumeration

3. Vulnerability Assessment

   • Automated scanning (Nessus/OpenVAS)
   • Web application scanning (Burp/ZAP)
   • Manual verification

4. Analysis

   • Correlate findings
   • Eliminate false positives
   • Prioritize by severity

5. Reporting

   • Document findings
   • Provide remediation guidance
   • Executive summary

Phase 9: Tool Selection Guide

Choose the right tool for each scenario:

Phase 10: Reporting and Documentation

Generate professional reports:

# Nmap XML to HTML
xsltproc nmap-output.xml -o report.html

# OpenVAS report export
gvm-cli socket --xml '<get_reports report_id="<id>" format_id="<pdf_format>"/>'

# Combine multiple scan results
# Use tools like Faraday, Dradis, or custom scripts

# Executive summary template:
# 1. Scope and methodology
# 2. Key findings summary
# 3. Risk distribution chart
# 4. Critical vulnerabilities
# 5. Remediation recommendations
# 6. Detailed technical findings

Imported: Purpose

Master essential security scanning tools for network discovery, vulnerability assessment, web application testing, wireless security, and compliance validation. This skill covers tool selection, configuration, and practical usage across different scanning categories.

Examples

Example 1: Ask for the upstream workflow directly

Use @scanning-tools to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @scanning-tools against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @scanning-tools for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @scanning-tools using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/scanning-tools, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Troubleshooting Notes

Imported: Troubleshooting

Scan Not Detecting Hosts

Solutions:

1. Try different discovery methods: nmap -Pn or nmap -sn -PS/PA/PU
2. Check firewall rules blocking ICMP
3. Use TCP SYN scan: nmap -PS22,80,443
4. Verify network connectivity

Slow Scan Performance

Solutions:

1. Increase timing: nmap -T4 or -T5
2. Reduce port range: --top-ports 100
3. Use Masscan for initial discovery
4. Disable DNS resolution: -n

Web Scanner Missing Vulnerabilities

Solutions:

1. Authenticate to access protected areas
2. Increase crawl depth
3. Add custom injection points
4. Use multiple tools for coverage
5. Perform manual testing
