Features:
✅ Interactive Project Requirements Editor:
- Opens when --prompt parameter is not provided in sandbox mode
- Uses inquirer editor type for multi-line text input
- Comprehensive default template with structured guidance
- Input validation (minimum 10 characters)
✅ Enhanced User Experience:
- Clear instructions on how to provide detailed requirements
- Pre-filled template with examples and categories:
* Feature descriptions
* Technical requirements (tech stack, styling)
* Design requirements (colors, layout, UI style)
- Real example at the bottom for reference
✅ Smart Flow:
- Only triggers when prompt is missing in sandbox mode
- Captures user input and continues with normal sandbox execution
- Maintains all existing functionality when --prompt is provided
This allows users to run sandbox mode without specifying --prompt
and get a guided experience to describe their project requirements.

Problem: When using --sandbox with --prompt, the system was showing
"Do you want to execute this prompt in Claude Code?" confirmation dialog
after installing the agent, even though sandbox mode should handle the
prompt execution directly.
Root Cause: The issue existed since the beginning. When --sandbox installs
an agent internally, the installIndividualComponents() function was also
checking for options.prompt and calling handlePromptExecution(), creating
a duplicate prompt handling path.
Solution: Added !options.sandbox condition to all three locations where
handlePromptExecution() is called:
1. Main template installation flow (line 372)
2. Individual components installation (line 1454)
3. Workflow components installation (line 1623)
This ensures prompt execution only happens in regular mode, not sandbox mode.

Corrections:
- Modal: Changed --agent=${componentPath} to correctly show folder/agent-name
- Index.html: Updated from --agent=frontend-developer to --agent=development-team/frontend-developer
- Steps section: Added missing agent specification in Cloud Sandbox step
- Tools section: Corrected E2B sandbox command format
This aligns with the CLI requirement where agents must be specified as:
--agent=folder/agent-name (e.g., development-team/frontend-developer)
The componentPath already contains the correct folder/name structure,
so this ensures the modal commands work correctly when copied.

Changes:
- E2B outputs now save to ./e2b-outputs/{timestamp}_{prompt}/ in project root
- No longer creates files inside .claude directory
- Added timestamp and sanitized prompt name for unique folder organization
- Improved find command to exclude .claude and node_modules directories
- Enhanced file filtering and organization for better user experience
Structure:
./e2b-outputs/
└── 20250106_143025_Create-React-app/
├── index.html
├── app.js
└── styles.css
This keeps E2B sandbox outputs separate from Claude Code configuration
and makes it easier for users to find and manage their generated files.

Changes:
- E2B Sandbox section now only appears for agent components
- Commands, MCPs, settings, hooks, and templates no longer show E2B option
- This aligns with the CLI implementation where --sandbox only works with --agent
- Keeps modal clean and relevant for each component type
Reasoning:
E2B sandbox execution is specifically designed for agent workflows since
agents provide the AI decision-making needed for complex cloud operations.
Other component types (commands, settings, etc.) are configuration-based
and don't require isolated execution environments.
