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.
Pinned to a commit: passed

About this skill
What it does
This skill enables AI agents to interact with SQLite databases using GRDB, a powerful Swift library. It allows agents to execute complex SQL queries, manage database schemas, and persist data directly within Swift applications without manual coding.
When to use it
- You need an agent to store user preferences or session state in a local SQLite file.
- Your project requires complex relational queries that standard JSON storage cannot handle efficiently.
- You are building a native iOS or macOS application and want the AI to manage data integrity automatically.
- You require rapid prototyping of database logic without writing boilerplate Swift code.
Key capabilities
- Executes raw SQL statements for data retrieval and manipulation.
- Manages database schema creation and migrations dynamically.
- Handles connection pooling and transaction management securely.
- Supports complex joins, aggregations, and filtering within SQLite.
Example prompts
- "Create a new table called 'users' with columns for id, name, and email, then insert three sample records."
- "Write a query to find all users who have made more than 5 purchases in the last month."
- "Update the status of all pending orders to 'shipped' and log the number of rows affected."
Tips & gotchas
Ensure your AI agent has read/write access to the target SQLite file path, as local permissions can block database operations. Be cautious with dynamic SQL generation; always validate inputs to prevent injection attacks when handling untrusted data sources.
