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
The efcore-patterns skill provides guidance on best practices and common patterns for using Entity Framework Core in .NET applications. It helps developers implement efficient data access, manage relationships between entities, and optimize queries using established design patterns.
When to use it
- You're designing a new data model with Entity Framework Core and need guidance on structuring your entities.
- You want to improve the performance of existing EF Core queries by applying known optimization techniques.
- You’re working on a team and need consistent practices for handling database operations in .NET applications.
- You're refactoring legacy code that uses raw SQL or inefficient data access patterns.
Key capabilities
- Explains common design patterns like repository, unit of work, and query object.
- Provides examples of how to configure EF Core for different scenarios.
- Offers advice on handling relationships, lazy loading, and eager loading.
- Covers best practices for query optimization and avoiding N+1 issues.
Example prompts
- "How can I implement the repository pattern with Entity Framework Core?"
- "What are some common patterns for optimizing LINQ queries in EF Core?"
- "Can you explain how to handle one-to-many relationships using EF Core?"
Tips & gotchas
- Ensure your project is targeting .NET 6 or later, as many modern EF Core patterns rely on newer features.
- Some advanced patterns may require additional libraries or custom implementations, so review the documentation for compatibility.
