## Tool Selection Guide

| Goal | Tool |
|------|------|
| Find models | `model_search` |
| Find datasets | `dataset_search` |
| Find Spaces/apps | `space_search` |
| Find papers | `paper_search` |
| Get repo README/details | `hub_repo_details` |
| Learn library usage | `hf_doc_search` → `hf_doc_fetch` |
| Run code on GPU/CPU | `hf_jobs` |
| Use Gradio apps as tools | `dynamic_space` |
| Generate images | `gr1_flux1_schnell_infer` or `dynamic_space` |

## Tips

- Use `sort="trendingScore"` to find what's popular now
- Use `sort="downloads"` to find battle-tested options
- Set `mcp=true` in `space_search` to find Spaces usable as tools
- Use `include_readme=true` in `hub_repo_details` for full model/dataset documentation
- For jobs accessing private repos, always include `secrets: {"HF_TOKEN": "$HF_TOKEN"}`
- Use `dynamic_space(operation="discover")` to see all available Space-based tasks
