Resize and validate App Store screenshots with current asc screenshot-size data and macOS sips. Use when preparing or fixing screenshots for App Store Connect submission.
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
# asc screenshot resize
Use this skill to prepare screenshots for App Store Connect. Do not rely on a hard-coded dimension table in this skill; the CLI owns the current size matrix.
## Source of truth
Always discover current accepted sizes from `asc` first:
```bash
asc screenshots sizes --output table
asc screenshots sizes --all --output table
```
For local validation before upload:
```bash
asc screenshots validate --path "./screenshots/iphone" --device-type "IPHONE_65" --output table
asc screenshots validate --path "./screenshots/ipad" --device-type "IPAD_PRO_3GEN_129" --output table
```
Common current device-type anchors:
- `IPHONE_65` for the common 6.5-inch iPhone screenshot set.
- `IPAD_PRO_3GEN_129` for the common 12.9/13-inch iPad screenshot set.
Run `asc screenshots sizes --all` when targeting other display types such as 6.9-inch iPhone, Apple TV, Mac, Vision Pro, iMessage, or Watch.
## Workflow
### 1. Sanitize filenames
macOS screenshots can contain hidden Unicode spaces that make tools fail with "not a valid file". Sanitize before batch work:
```bash
python3 -c "
import os
for f in os.listdir('.'):
clean = f.replace('\u202f', ' ')
if f != clean:
…Read the whole file at its exact version.
How to install
mdr add jordancoin/ios-skills-collection/asc-screenshot-resize@sha256:311b549c07d90ef5The line at the top of this page pins the label git:20260910.90d1807, 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.
