- Removed full code output from console (code is saved to files anyway)
- Simplified file download logs to show only filenames
- Removed redundant separators and verbose output
- Keep only essential progress indicators:
- Agent installation
- Code generation progress
- File extraction and save location
Users now see only the essential progress without code dumps.

- Updated @anthropic-ai/claude-agent-sdk from ^0.1.0 to ^0.1.23
- Replaced manual agent loading with automatic settingSources: ['project']
- Removed temporary workaround for agent loading (SDK now properly supports it)
- Added gitignore entries for local test directories
- Verified settingSources functionality works with SDK v0.1.23
The latest SDK version properly supports automatic agent loading from .claude/ directory,
eliminating the need for manual file reading and systemPrompt manipulation.

The Agent SDK returns the final response in a message with type='result'
and the content in message.result, not in type='text' messages.
This was discovered through direct testing of the SDK.
- Current SDK version (^0.1.0) does not properly support settingSources
- Manually loading agent content as workaround
- TODO: Revisit when SDK properly supports automatic agent loading
Fixed Cloudflare sandbox to save generated files in project root using
timestamp-based directories, matching E2B's sandbox-{id} pattern.
**Changes**:
- Modified launcher.ts to accept targetDir parameter (5th argument)
- Updated LauncherConfig interface with optional targetDir field
- Modified displayResults() to use targetDir instead of process.cwd()
- Fixed TypeScript errors (workerUrl undefined, unused language variable)
- Updated src/index.js to pass targetDir to launcher
- Added cloudflare-*/ and sandbox-*/ to .gitignore
- Updated IMPLEMENTATION_SUMMARY.md with file structure details
**Directory Structure**:
- Before: `.claude/sandbox/cloudflare/cloudflare-output/`
- After: `your-project/cloudflare-{timestamp}/`
**Pattern Comparison**:
- E2B: `your-project/sandbox-{id}/`
- Cloudflare: `your-project/cloudflare-{timestamp}/`
Files now download to clean, timestamped directories in the project root,
improving organization and matching user expectations from E2B behavior.

- Use os.getcwd() to get the directory where command was executed
- Download files to sandbox-{id} folder in user's current directory
- Remove hardcoded relative path assumptions (../../)
- Add debugging output to show current working directory

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.
