Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# SKILL · Real-ESRGAN x4plus (Super-Resolution — App Builder Pack)

> Injected when user selects `real-esrgan-x4plus` Pack. Teaches how to *interpret*
> Real-ESRGAN output (upscaled image), not how to call it.
>
> Both flows valid: you MAY call `appbuilder_run` to verify I/O shape;
> user's WebUI calls it over HTTP API. A Run result may already be in
> conversation — interpret it using this file.

## 1. What this Pack does

Real-ESRGAN x4plus: image/video super-resolution from xinntao/Real-ESRGAN, running on Snapdragon X Elite NPU (QNN HTP FP16). Single QNN context binary:

1. **real_esrgan_480x640_fp16.bin** — RRDB-based generator, input [1,3,480,640] NCHW, output [1,3,1920,2560] NCHW

**Input:** RGB image of any size (PNG, JPG, JPEG, WebP, BMP, TIFF). Max 20 MB.

**Output:** JSON with `output_path`, `original_size`, `upscaled_size`, `scale`.

Fixed 4x upscale factor. Arbitrary input sizes handled via tiled inference with overlap blending (tile 640×480 input, 32px overlap, linear feathering at seams).

**Performance:** ~800 ms per tile on NPU. Total time depends on image size (number of tiles).

How to install

The exact contents, by fingerprint
mdr add qualcomm/qai-appbuilder/real-esrgan-x4plus@sha256:1992383fce6e04d8

The line at the top of this page pins the label git:20260822.fbacac1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
