🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION)

You MUST send this notification BEFORE doing anything else when this skill is invoked.

  1. Send voice notification:

    curl -s -X POST http://localhost:8888/​notify \
      -H "Content-Type: application/​json" \
      -d '{"message": "Running the WORKFLOWNAME workflow in the WebAssessment skill to ACTION"}' \
      > /​dev/​null 2>&1 &
    
  2. Output text notification:

    Running the **WorkflowName** workflow in the **WebAssessment** skill to ACTION...
    

This is not optional. Execute this curl command immediately upon skill invocation.

Skill Integration

WebAssessment coordinates with specialized skills:

PhaseSkillPurpose
Scope DefinitionReconCorporate structure, domain enumeration
Target DiscoveryReconSubdomains, endpoints, ports
UnderstandingWebAssessmentApp narrative, user flows, sensitive data
Threat ModelingWebAssessmentAttack scenarios, test prioritization
Injection TestingPromptInjectionLLM-specific attacks
IntelligenceOSINTPeople, companies, social media

Assessment Workflow

1. Corporate Structure (Recon) → Define scope and targets
2. Subdomain Enumeration (Recon) → Find all domains
3. Endpoint Discovery (Recon) → Extract JS endpoints
4. Understand Application → Build app narrative
5. Create Threat Model → Prioritize attack scenarios
6. Execute Testing → Test against identified threats
7. Report Findings → Document with PoCs

Recon Skill Tools

WebAssessment uses tools from the Recon skill:

# Corporate structure for scope
bun ~/​.claude/​skills/​Recon/​Tools/​CorporateStructure.ts target.com

# Subdomain enumeration
bun ~/​.claude/​skills/​Recon/​Tools/​SubdomainEnum.ts target.com

# Endpoint discovery from JavaScript
bun ~/​.claude/​skills/​Recon/​Tools/​EndpointDiscovery.ts https://target.com

# Port scanning
bun ~/​.claude/​skills/​Recon/​Tools/​PortScan.ts target.com

# Path discovery
bun ~/​.claude/​skills/​Recon/​Tools/​PathDiscovery.ts https://target.com

UnderstandApplication Output

Produces structured narrative including:

  • Summary: Purpose, industry, user base, critical functions
  • User Roles: Access levels and capabilities
  • User Flows: Step-by-step processes with sensitive data
  • Technology Stack: Frontend, backend, auth, third-party
  • Attack Surface: Entry points, inputs, file uploads, websockets

CreateThreatModel Output

Generates prioritized attack plan:

  • Threats: OWASP/​CWE mapped with risk scores
  • Attack Paths: Multi-step attack scenarios
  • Test Plan: Prioritized with tool suggestions
  • Effort Estimates: Quick/​medium/​extensive per threat

6-Phase Pentest Methodology

Phase 0: Scoping & Preparation Phase 1: Reconnaissance (Recon skill) Phase 2: Mapping (content discovery) Phase 3: Vulnerability Analysis Phase 4: Exploitation Phase 5: Reporting

Key Principles

  1. Authorization first - Never test without explicit permission
  2. Understand before testing - Build app narrative first
  3. Threat model guides testing - Don't test blindly
  4. Breadth then depth - Wide recon, focused exploitation
  5. Document everything - Notes, screenshots, commands

Examples

Example 1: Full assessment workflow

User: "Security assessment on app.example.com"
→ Run UnderstandApplication to build narrative
→ Run CreateThreatModel to prioritize testing
→ Follow MasterMethodology with threat model guidance
→ Report findings with OWASP/​CWE references

Example 2: Quick threat model

User: "How would I attack this app?"
→ Run CreateThreatModel on target
→ Get prioritized attack paths
→ Get test plan with tool suggestions

Example 3: Integrate with Recon

User: "Assessment on target.com including all subdomains"
→ CorporateStructure (Recon) → Find parent/​child companies
→ SubdomainEnum (Recon) → Find all subdomains
→ EndpointDiscovery (Recon) → Extract JS endpoints
→ UnderstandApplication → Build app narrative
→ CreateThreatModel → Generate attack plan
