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 leverages Python's async context manager to ensure resources are properly managed within asynchronous code. It facilitates cleaner, more reliable resource acquisition and release (like database connections or file handles) even in the presence of exceptions. This promotes robust and maintainable asynchronous applications by automatically handling setup and teardown operations.
When to use it
- Database Interactions: When connecting to a database asynchronously, ensuring the connection is closed regardless of errors.
- File Handling: Automatically closing files after reading or writing in an asynchronous context.
- Network Connections: Managing socket connections gracefully within asynchronous tasks.
- Resource Cleanup: Guaranteeing that temporary resources are released when they're no longer needed, preventing leaks.
Key capabilities
- Automatic resource acquisition and release
- Exception safety – ensures cleanup even if errors occur
- Asynchronous compatibility
- Clean code structure for managing resources
Example prompts
- "Write an asynchronous function to read a file using an async context manager."
- "Show me how to use an async context manager to connect to and query a database asynchronously."
- "Demonstrate the benefits of using
async withover manual resource management in Python."
Tips & gotchas
- Requires familiarity with asynchronous programming concepts in Python.
- The skill assumes you are already writing Python code; it doesn't teach basic Python syntax.
