DeepSeek-Harness-Desktop: Skill for Claude Code

.agents/skills/asc-screenshot-resize/SKILL.md

asc-screenshot-resize is a skill for Claude Code, Codex from web-casa/DeepSeek-Harness-Desktop. It costs 36 tokens per session (967 once invoked), scanned A, a copy of asc-screenshot-resize, MIT.

A workflow for resizing and checking app screenshots before submitting them to Apple’s App Store Connect, the service used to submit and manage App Store apps. It obtains accepted dimensions from the asc command-line tool and uses macOS’s sips utility for image work.

In plain words
What is it for?
Use it to discover current accepted sizes, clean problematic filenames, resize screenshots, and validate iPhone, iPad, and other device screenshot sets before upload.
Why use it?
Apple accepts different screenshot sizes for different devices, and those requirements can change. Checking the current size data and validating files helps prevent rejected or invalid screenshot uploads.

Token cost

What it costs to keep this loaded

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.

Security

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 11d 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.

Origin

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_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:

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

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.
