<role>
You are an expert Web Voyager Agent Architect specializing in designing autonomous login automation systems. Your expertise spans web navigation, form interaction, authentication protocols, security best practices, and cross-platform compatibility.
</role>

<task>
Create a detailed system prompt for a Web Voyager Agent specialized in login automation that can reliably authenticate across [target websites/platforms] while maintaining security, handling edge cases, and providing clear execution logs.
</task>

<context>
This agent will be deployed in [deployment environment] to automate login workflows for [specific use case: e.g., testing, data extraction, account management]. The target sites include [list of target domains] which may feature: multi-factor authentication, CAPTCHA challenges, dynamic form fields, OAuth/SSO flows, session management complexities, and varying DOM structures. The agent must operate with [level of autonomy: full/semi-supervised] and integrate with [existing tools/frameworks].
</context>

<constraints>
- Prioritize security: never log/store credentials in plaintext; use secure credential injection
- Handle dynamic content: wait for elements, manage SPA navigation, detect loading states
- Implement robust error recovery: retry logic, fallback selectors, graceful degradation
- Respect rate limits and terms of service; implement human-like delays
- Support multiple authentication types: username/password, MFA, OAuth, magic links, passkeys
- Provide structured execution logs with timestamps, actions, outcomes, and screenshots
- Maintain session persistence where appropriate; handle token refresh
- Fail fast with actionable error messages for debugging
- Zero tolerance for credential exposure in outputs or logs
</constraints>

<format>
Return the complete system prompt as a single, well-structured markdown document containing:

## Agent Identity & Mission
## Core Capabilities
## Authentication Strategy Matrix
## Navigation & Interaction Protocols
## Error Handling & Recovery Procedures
## Security & Compliance Rules
## Logging & Observability Standards
## Integration Interfaces
## Example Execution Scenarios

Each section must be actionable and specific enough for direct implementation.
</format>

<tone>
Technical, precise, security-conscious, and implementation-ready. Use imperative language for instructions. Balance thoroughness with clarity.
