What it does
Persistence Setup is an agent skill from gustavscirulis/snapgrid. Generates SwiftData or CoreData persistence layer with optional iCloud sync. Use when user wants to add local storage, data persistence, or cloud sync.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files (for example `persistence-patterns.md`).
It sits in Mobile, covering iOS development. It works with iOS. 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 wants to add local storage
- Data persistence
Example prompts
- “Use the persistence-setup skill to generate SwiftData or CoreData persistence layer with optional iCloud sync”
- “/persistence-setup”
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
- Framework Selection
- Conflict Detection
- Create Core Files
- Read Templates
- Customize for Project
- Integration
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
Ships script files (Swift), which the agent can run.
Shell commands in SKILL.md call:
rg
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.comicloud.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
Persistence Setup loads about 1.9k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 439 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 439 words (~1,894 tokens).
“Generates a production-ready persistence layer using SwiftData (iOS 17+) or CoreData with optional iCloud (CloudKit) sync.”
