asc-screenshot-resize skillA
asc-screenshot-resize is agent-read markdown (skill) from jordancoin/ios-skills-collection: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260910.90d1807mdr add jordancoin/ios-skills-collection/asc-screenshot-resize@sha256:311b549c07d90ef5Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
