upscaler SKILL.md skillA
upscaler from mikefluff/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mikefluff/skills/upscaler@git:20260803.e8ff76fPins git:20260803.e8ff76f in mdr.lock. Pin the fingerprint instead.

Image upscaling utility — image in, upscaled image out (2× / 4× / 8×). Wraps Replicate upscalers (Real-ESRGAN default; GFPGAN for faces, SwinIR, clarity-upscaler). Optional --face-enhance for portrait restoration. Use when: 'upscale', 'enhance resolution', 'sharpen low-res image', 'make this bigger', 'улучши разрешение', 'увеличь фотку', 'апскейл'.
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
<objective>
Image upscaling utility. Single input image → output upscaled by 2× / 4× / 8× factor. Sharper, higher resolution, with AI-based detail interpolation (vs simple bilinear / bicubic).
This skill does NOT:
- Generate new content — it ENHANCES existing pixels via super-resolution models
- Magic-restore an image from junk-tier (16×16 thumbnail to 4K HD) — input quality matters; garbage in, garbage out
- Handle video — one frame at a time only
- Vectorize — output remains raster PNG
- Remove background (chain with `bg-remover`)
- Fix major artifacts (deep blur, motion blur, JPEG mosquito noise at extreme levels) — works best on mildly low-res / soft images
</objective>
## ROLE
Read input image → call a Replicate-hosted upscaler → save the upscaled output at the requested scale factor.
## PIPELINE
1. **Resolve input**:
- `--image <path-or-url>` (required)
2. **Pick provider**:
- Default: `nightmareai/real-esrgan` (popular general-purpose, ~$0.005/image at 4×)
- Alternatives via `--replicate-model <id>`:
- `nightmareai/real-esrgan` — default; best general
- `tencentarc/gfpgan` — face-focused (best for portraits)

How to install
mdr add mikefluff/skills/upscaler@sha256:08ba5cb82aba91fcThe line at the top of this page pins the label git:20260803.e8ff76f, 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.
