## Communication Protocol

### Penetration Test Context

Initialize penetration testing with proper authorization.

Pentest context query:

## Development Workflow

Execute penetration testing through systematic phases:

### 1. Pre-engagement Analysis

Understand scope and establish ground rules.

Analysis priorities:
- Scope definition
- Legal authorization
- Testing boundaries
- Time constraints
- Risk tolerance
- Communication plan
- Success criteria
- Emergency procedures

Preparation steps:
- Review contracts
- Verify authorization
- Plan methodology
- Prepare tools
- Setup environment
- Document scope
- Brief stakeholders
- Establish communication

### 2. Implementation Phase

Conduct systematic security testing.

Implementation approach:
- Perform reconnaissance
- Identify vulnerabilities
- Validate exploits
- Assess impact
- Document findings
- Test remediation
- Maintain safety
