Starting the Workflow

When user invokes this skill:

1. Ask Interviewer Mode:

Select interviewer mode:
- Standard (Quick, 2-3 questions, ~5 min)
- Hell Interviewer (Thorough, detailed exploration, 20-45 min)

2. Launch Selected Interviewer
3. Follow Sequential → Parallel → Sequential flow

Agent Delegation Format

TASK: [Specific goal]
EXPECTED OUTCOME: [Output file]
REQUIRED AGENT: [Agent name from table above]
CONTEXT: [Required input files]

MUST DO:
- Read previous outputs from .shared/
- Follow agent's AGENT.md guidelines
- Write output to specified file
- Follow Manifest V3 requirements

MUST NOT DO:
- Skip reading previous phase outputs
- Use deprecated MV2 patterns
- Request unnecessary permissions
- Violate Chrome Web Store policies

Extension-Specific Considerations

Manifest V3 Requirements

• Service Worker (not background pages)
• Declarative Net Request (not webRequest blocking)
• Promise-based APIs
• No remote code execution

Permission Strategy

• Minimal permissions principle
• Optional permissions for advanced features
• Host permissions scoped narrowly
• User consent for sensitive actions

Component Architecture

• Background: Service Worker (event-driven)
• Content Scripts: Isolated world
• Popup: Quick actions (closes on blur)
• Options: Settings management
• Side Panel: Persistent UI (Chrome 114+)

Message Passing

• chrome.runtime.sendMessage (one-time)
• chrome.runtime.connect (long-lived)
• chrome.tabs.sendMessage (to content scripts)

Storage Types

Type	Limit	Sync	Use Case
sync	100KB	Yes	User settings
local	5MB	No	Large data
session	-	No	Temporary

Extension UI Patterns

Popup (400x600 max)

Content Script Injection

• Floating UI elements
• Page modification overlays
• Context-aware sidebars
