What it does
Asc Screenshot Resize is an agent skill from CamilleScholtz/swmpc. 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.
Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering App store release. It works with App Store Connect and macOS. The repository describes itself as: An MPD client for macOS & iOS.
When your agent uses it
- Fixing screenshots for App Store Connect submission
- Tasks that involve App store release
Example prompts
- “/asc-screenshot-resize”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Sanitize filenames
- Inspect dimensions and metadata
- Resize only after choosing a target from asc
- Validate outputs with asc
- Upload only after validation
What it can do on your machine
Read from SKILL.md and the folder at commit 51fa7cb. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Asc Screenshot Resize loads about 927 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 248 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (EUPL-1.2) doesn't allow us to republish the file, so here is its outline and opening line. It has 248 words (~927 tokens).
“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.”
