What it does
Swiftdata Architecture is an agent skill from KartikLabhshetwar/better-shot. Deep dive into SwiftData design patterns and best practices. Covers schema design, query patterns, repository pattern, and performance optimization. Use when designing data models or improving SwiftData usage.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `performance.md`, `query-patterns.md` and `repository-pattern.md`).
It sits in Development, covering Design patterns, Database schema design and Performance optimization. It works with macOS and SwiftUI. The repository describes itself as: Screenshot, screen recording, and video editor for macOS. Native SwiftUI app with capture deck, 75+ customizable shortcuts, URL scheme automation, and self-hosted cloud sharing…
When your agent uses it
- Designing data models
- Improving SwiftData usage
Example prompts
- “/swiftdata-architecture”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Missing Unique Constraints
- Fetching Too Much Data
- Modifying Models on Wrong Context
- Understand the Data Model
- Review Against Module Guidelines
- Provide Structured Feedback
What it can do on your machine
Read from SKILL.md and the folder at commit 7242211. 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
No URLs in SKILL.md.
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 Architecture loads about 1.2k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 397 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 397 words (~1,195 tokens).
“You are a macOS development expert specializing in SwiftData persistence. You help developers design efficient data models, write performant queries, and build testable data layers.”
