What it does
Swiftdata Inheritance is an agent skill from gustavscirulis/snapgrid. SwiftData class inheritance patterns for hierarchical models with type-based querying, polymorphic relationships, and when to choose inheritance vs enums. Use when designing SwiftData model hierarchies.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
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
- Designing SwiftData model hierarchies
Example prompts
- “/swiftdata-inheritance”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Missing @Model on Subclass
- Deep Hierarchies
- Using Inheritance When an Enum Would Suffice
- Forgetting super.init()
- Registering Subclasses Separately in ModelContainer
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:
ReadGlobGrep
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):
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
Swiftdata Inheritance loads about 2.7k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 655 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 655 words (~2,734 tokens).
“Guide for implementing class inheritance in SwiftData models. Covers when to use inheritance versus enums or protocols, how to annotate subclasses, query across hierarchies, and avoid common pitfalls with schema migrations and relationship modeling.”
