 ### Implement CLI Progress Reporting + pv Support  
 **ID:** NUT-011  
-**Status:** Triage  
+**Status:** Fixed  
 **Type:** Feature  
 
 **Description:**  
-Integrate with `pv` for progress reporting and support streaming uploads.
+Integrate rich progress reporting with `indicatif` (speed, ETA, byte counters), pipe-friendly detection (e.g. `pv` and headless/script pipes), and manual size hints for stdin streams.
 
 **Requirements:**  
-- [ ] Detect file size  
-- [ ] Report progress to stdout  
-- [ ] Support piping from `pv`  
+- [x] Detect file size & support `--size` hint for stdin streams  
+- [x] Rich terminal progress bar with speed (MB/s), ETA, bytes transferred, and percentage  
+- [x] Auto-detect TTY: silence progress bars when piped to downstream tools or files  
+- [x] Support explicit `--no-progress` flag  
+- [x] Support piping directly from `pv` or Unix pipelines without display conflicts  
 
 **Dependencies:**
