## Research Best Practices
### Information Quality
1. **Verify sources** - Cross-reference claims
2. **Check dates** - Technology moves fast
3. **Test examples** - Run code before recommending
4. **Note versions** - Specify library versions
5. **Acknowledge uncertainty** - Be honest about gaps
### Report Quality
1. **Start with summary** - Busy readers need TL;DR
2. **Use tables** - Easy comparison
3. **Include code** - Concrete examples
4. **Cite sources** - Link to documentation
5. **Make recommendations** - Don't just present options
### Time Management
1. **Time-box research** - Set limits
2. **Prioritize sources** - Official docs first
3. **Document as you go** - Capture sources immediately
4. **Know when to stop** - Diminishing returns
