Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.00967 |
| Opus 5.5 | $0.00014 | $0.00387 |
| Sonnet 5.5 | $0.00007 | $0.00193 |
| Haiku 4.5 | $0.00004 | $0.00097 |
Grade A, and why
asc-screenshot-resize scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to asc-screenshot-resize — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
asc screenshots sizes --output table
asc screenshots sizes --all --output table
For local validation before upload:
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_65for the common 6.5-inch iPhone screenshot set.IPAD_PRO_3GEN_129for 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:
python3 -c "
import os
for f in os.listdir('.'):
clean = f.replace('\u202f', ' ')
if f != clean:
os.rename(f, clean)
print(f'Renamed: {clean}')
"
2. Inspect dimensions and metadata
sips -g pixelWidth -g pixelHeight screenshot.png
sips -g hasAlpha -g space screenshot.png
App Store Connect rejects screenshots with alpha transparency. Strip alpha by round-tripping through JPEG:
sips -s format jpeg input.png --out /tmp/asc-screenshot-no-alpha.jpg
sips -s format png /tmp/asc-screenshot-no-alpha.jpg --out output.png
rm /tmp/asc-screenshot-no-alpha.jpg
Batch-strip alpha from PNGs:
for f in *.png; do
if sips -g hasAlpha "$f" | grep -q "yes"; then
sips -s format jpeg "$f" --out /tmp/asc-screenshot-no-alpha.jpg
sips -s format png /tmp/asc-screenshot-no-alpha.jpg --out "$f"
rm /tmp/asc-screenshot-no-alpha.jpg
echo "Stripped alpha: $f"
fi
done
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
