You MUST send this notification BEFORE doing anything else when this skill is invoked.
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 &
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.
Security assessment infrastructure integrating reconnaissance, threat modeling, and vulnerability testing.

| "understand application", "what does this app do", "map the application" | UnderstandApplication |
| "threat model", "attack scenarios", "how would I attack" | CreateThreatModel |
| "pentest", "security assessment", "test for vulnerabilities" | Pentest/MasterMethodology |
| "fuzz with ffuf", "directory fuzzing", "content discovery" | Ffuf/FfufGuide |

WebAssessment coordinates with specialized skills:
| Phase | Skill | Purpose |
|---|---|---|
| Scope Definition | Recon | Corporate structure, domain enumeration |
| Target Discovery | Recon | Subdomains, endpoints, ports |
| Understanding | WebAssessment | App narrative, user flows, sensitive data |
| Threat Modeling | WebAssessment | Attack scenarios, test prioritization |
| Injection Testing | PromptInjection | LLM-specific attacks |
| Intelligence | OSINT | People, companies, social media |
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
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
Produces structured narrative including:
Generates prioritized attack plan:
| Category | Triggers On |
|---|---|
| Authentication | Auth mechanisms detected |
| Access Control | Multiple user roles |
| Injection | All web apps |
| Data Exposure | Sensitive data identified |
| File Upload | Upload functionality |
| API Security | API endpoints |
| WebSocket | WebSocket detected |
| Business Logic | All web apps |
| Payment Security | Payment flows |
Phase 0: Scoping & Preparation Phase 1: Reconnaissance (Recon skill) Phase 2: Mapping (content discovery) Phase 3: Vulnerability Analysis Phase 4: Exploitation Phase 5: Reporting

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
