`~/.claude/PAI/USER/SKILLCUSTOMIZATIONS/WebAssessment/`

If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.


## 🚨 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**:
   ```bash
   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...

# WebAssessment Skill

Security assessment infrastructure integrating reconnaissance, threat modeling, and vulnerability testing.


## Workflow Routing

| Trigger | Workflow |
|---------|----------|
| "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 |
| "OSINT", "reconnaissance", "open source intelligence" | osint/MasterGuide |
| "test web app", "Playwright", "browser automation" | webapp/TestingGuide |
| "bug bounty", "bounty programs" | bug-bounty/Programs |
| "vulnerability analysis with AI", "Gemini analysis" | VulnerabilityAnalysisGemini3 |

## Skill Integration

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 |

## 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:

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

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

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

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

# Path discovery
bun ~/.claude/skills/Security/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

## Threat Categories

| 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 |

## 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
```
