Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
What it does
This skill provides access to Core Data, Apple’s framework for managing the model layer of applications. It allows AI agents to interact with persistent data stores within Swift applications, enabling features like saving user preferences, storing application state, and handling complex data relationships. The agent can query, modify, and create data objects using Core Data's API.
When to use it
- Saving User Preferences: An agent needs to persistently store a user’s preferred theme (light/dark) within a Swift iOS app.
- Managing Application State: An agent is tasked with restoring the state of a game after an application restart, including player progress and inventory.
- Handling Complex Data Relationships: The agent must create and manage relationships between different data entities in a social media application (e.g., users, posts, comments).
- Data Migration: An agent needs to update a Core Data model schema and migrate existing data to the new format.
Key capabilities
- Querying persistent store data
- Creating new managed objects
- Modifying existing managed objects
- Deleting managed objects
- Managing relationships between entities
Example prompts
- "Create a new user with name 'Alice' and email '[email protected]'."
- "Fetch all posts created by user 'Bob'."
- "Delete the comment with ID 123."
- "Update the theme preference to dark mode."
Tips & gotchas
- Requires a working Swift project utilizing Core Data. The agent will need access to the managed object model and persistent store coordinator.
