# Work Progress

<!-- this_file: WORK.md -->

## Current Status

**Version**: 1.0.0 (Complete)

All core modules implemented, tested, and documented.

## Implementation Summary

### Completed Modules

1. **url22md/__init__.py** - Package metadata and version
2. **url22md/__main__.py** - Fire CLI with full argument parsing
3. **url22md/converter.py** - URL conversion orchestration and concurrent processing
4. **url22md/tools.py** - Six extraction tool implementations
5. **url22md/utils.py** - Utility functions for URL handling, proxy config, JSONL I/O

### Documentation

- **README.md** - Installation, usage examples, tool reference, CLI documentation
- **PLAN.md** - Architecture and future roadmap
- **TODO.md** - Feature checklist (completed and future items)
- **CHANGELOG.md** - Version history and release notes
- **DEPENDENCIES.md** - Detailed dependency rationale
- **WORK.md** - This file

## Test Coverage

- Unit tests for core utilities (url2filename, proxy config, JSONL operations)
- Tool result validation tests
- Quality assessment tests
- Mock extraction tests

### Tests Passing

All implemented features verified:
- URL deduplication and filtering
- Filename generation from URLs
- JSONL read/write operations
- Proxy URL construction
- Quality scoring algorithm
- Tool cascade behavior

## Next Steps

### For Integration Testing

1. Test with live URLs from various domains
2. Validate cloud API integrations (Firecrawl, Jina)
3. Performance benchmarking with large batches
4. Proxy functionality validation with Webshare

### For Enhancement

1. Add custom quality threshold CLI flag
2. Implement HTML/JSON output formats
3. Add per-domain rate limiting
4. Create plugin system for custom extractors
5. Expand test coverage to 80%+

## Known Limitations

- Cloud APIs (Firecrawl, Jina) require valid API keys
- Playwright requires Chromium browser binary
- Crawl4ai requires setup step for browser drivers
- Quality scoring is heuristic-based, not ML-trained
- No built-in authentication for protected pages
