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 expert assistance with Python backend development specifically within FastAPI applications. It helps with tasks like defining API endpoints, creating data schemas using Pydantic v2, building SQLAlchemy 2.0 models and queries, implementing data access layers (repository pattern), and managing business logic. The skill is designed to streamline the creation and maintenance of backend services and APIs.
When to use it
- Developing or modifying FastAPI route handlers (endpoints).
- Defining Pydantic v2 schemas for request and response bodies.
- Creating SQLAlchemy 2.0 async models, queries, and relationships.
- Implementing the repository pattern for data access logic.
- Writing service layer business logic within your application.
Key capabilities
- FastAPI route handler development
- Pydantic v2 schema definition and updates
- SQLAlchemy 2.0 async model creation and querying
- Repository pattern implementation
- Service layer business logic writing
- Alembic migration generation and execution
- Dependency injection using
Depends()
Example prompts
- "Generate a FastAPI route handler for creating a new user, including Pydantic schema validation."
- "Write an SQLAlchemy 2.0 model for a 'Product' with attributes like name, description, and price."
- "Implement the repository pattern for accessing users from a database."
Tips & gotchas
- This skill is not intended for writing tests (use
pytest-patternsinstead). - Avoid using it for FastAPI framework mechanics such as middleware or CORS configuration; use
fastapi-patternsfor those tasks. - The skill assumes a project structure similar to the example provided in the documentation, including directories like
app/core,app/models, andapp/repositories.
