What it does
Background Processing is an agent skill from gustavscirulis/snapgrid. Generates background processing infrastructure with BGTaskScheduler, background refresh, background downloads, and silent push handling. Use when user needs background tasks, periodic refresh, background URLSession downloads, or silent push notification processing.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `templates.md`).
It sits in Mobile. The repository describes itself as: SnapGrid is an open-source Mac app for collecting, organizing, and analyzing UI screenshots. It uses AI to automatically detect UI components and patterns, making it a powerful…
When your agent uses it
- User needs background tasks
- Periodic refresh
- Background URLSession downloads
- Silent push notification processing
Example prompts
- “Use the background-processing skill to generate background processing infrastructure with BGTaskScheduler, background refresh, background downloads…”
- “/background-processing”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash, AskUserQuestion
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Project Context Detection
- Existing Background Task Detection
- Info.plist Check
- Read Templates
- Create Core Files
- Create Feature-Specific Files
- Determine File Location
What it can do on your machine
Read from SKILL.md and the folder at commit eb7eaf4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrepBashAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift and xml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
developer.apple.com
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
Background Processing loads about 2.4k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 709 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Write, Edit, Glob, Grep, Bash, AskUserQuestion
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 (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 709 words (~2,395 tokens).
“Generate production background processing infrastructure -- BGTaskScheduler for periodic refresh and long-running tasks, background URLSession for downloads/uploads that survive app termination, and silent push handling for server-triggered updates.”
