What it does
Background Processing is an agent skill from dpearson2699/swift-ios-skills. Schedule and execute background work on iOS using BGTaskScheduler. Use when registering BGAppRefreshTask for short background fetches, BGProcessingTask for long-running maintenance, BGContinuedProcessingTask (iOS 26+) for foreground-started work that continues in background, background URLSession downloads, or background push notifications. Covers Info.plist configuration, expiration handling, task completion, and debugging with simulated launches.
Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/background-task-patterns.md`).
It sits in Mobile, covering iOS development. It works with iOS. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- Registering BGAppRefreshTask for short background fetches
- BGProcessingTask for long-running maintenance
- BGContinuedProcessingTask (iOS 26+) for foreground-started work that continues in background
- Background URLSession downloads
Example prompts
- “/background-processing”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Missing Info.plist identifiers
- Not calling setTaskCompleted(success:)
- Ignoring the expiration handler
- Scheduling too frequently
- Over-relying on background time
What it can do on your machine
Read from SKILL.md and the folder at commit 8d90fd1. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift, xml and json).
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):
sosumi.ai
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 3.8k tokens when it runs, and up to ~6.9k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 564 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 (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 564 words (~3,762 tokens).
“Register, schedule, and execute background work on iOS using the BackgroundTasks framework, background URLSession, and background push notifications.”
