What it does
Cloudkit is an agent skill from dpearson2699/swift-ios-skills. Implement, review, or improve CloudKit and iCloud sync in iOS/macOS apps. Use when working with CKContainer, CKRecord, CKQuery, CKSubscription, CKSyncEngine, CKShare, NSUbiquitousKeyValueStore, or iCloud Drive file coordination; when syncing SwiftData models via ModelConfiguration with cloudKitDatabase; when handling CKError codes for conflict resolution, network failures, or quota limits; or when checking iCloud account status before performing sync operations.
Its SKILL.md is about 4.8k 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/cloudkit-patterns.md`).
It sits in Mobile. It works with iOS and macOS. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- Working with CKContainer
- NSUbiquitousKeyValueStore
- ICloud Drive file coordination
- Syncing SwiftData models via ModelConfiguration with cloudKitDatabase
Example prompts
- “/cloudkit”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Choose the database scope and sync owner; verify capability, container, account status, schema, and environment before writing records.
- Make a local change durable, enqueue it, then let subscriptions or CKSyncEngine drive remote work rather than polling.
- Persist change tokens or sync-engine state after successful application.
- Test offline edits, partial failure, rate limiting, token expiry, conflict, account loss, zone deletion, and relaunch.
- On failure, classify the CKError, restore the affected fixture or queue item, apply the documented retry/reset/merge action, and rerun the…
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).
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
Cloudkit loads about 4.8k tokens when it runs, and up to ~8.5k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 924 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 924 words (~4,775 tokens).
“Sync data across devices using CloudKit, iCloud key-value storage, and iCloud Drive. Covers container setup, record CRUD, queries, subscriptions, CKSyncEngine, SwiftData integration, conflict resolution, and error handling.”
