Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

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

    Only contacts known or declared hosts: github.com.

    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.

    Hosts contacted

    github.comsource host

  • 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

    Scanned microck/ordinary-claude-skills at 1056d293d4.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides access to a collection of SQL optimization patterns. It can analyze poorly performing SQL queries and suggest improvements based on established best practices, such as utilizing indexes or rewriting joins for better efficiency. The goal is to help users identify bottlenecks in their database interactions and improve query execution times.

When to use it

  • Slow Query Analysis: When a specific SQL query takes an unexpectedly long time to execute.
  • Database Performance Tuning: As part of a broader effort to optimize the overall performance of a database system.
  • Query Optimization Recommendations: To get suggestions for improving existing, but inefficient, SQL queries.
  • Learning Best Practices: To understand common SQL optimization techniques and apply them proactively.

Key capabilities

  • Provides SQL query optimization patterns.
  • Analyzes poorly performing SQL queries.
  • Suggests improvements to SQL queries.

Example prompts

  • "Analyze this query: SELECT * FROM orders WHERE customer_id = 123; and suggest optimizations."
  • "What are some common ways to optimize a query with multiple JOIN clauses?"
  • “How can I improve the performance of a query that is using a full table scan?”

Tips & gotchas

This skill requires you to provide valid SQL queries for analysis. The effectiveness of suggestions depends on the complexity of the query and the database schema; it's not a magic bullet, but a tool to aid in optimization efforts.
