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

    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

    Scanned patricio0312rev/skills at 79ea6af485.

    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 helps you optimize SQL queries for better performance within your database. It analyzes existing queries and provides suggestions for improvement, including identifying slow operations like full table scans and recommending index creation to speed up data retrieval. The tool uses EXPLAIN ANALYZE output to pinpoint bottlenecks and offer targeted solutions.

When to use it

  • You're experiencing slow query performance in your database application.
  • You want to understand why a specific SQL query is taking a long time to execute.
  • You need assistance identifying missing indexes that could improve query efficiency.
  • You are looking for guidance on how to interpret EXPLAIN ANALYZE output.

Key capabilities

  • Analyzes SQL queries using EXPLAIN ANALYZE.
  • Identifies inefficient operations like sequential scans.
  • Recommends the creation of indexes to improve query performance.
  • Provides example code for creating suggested indexes.

Example prompts

  • "Can you analyze this SQL query and tell me how to make it faster? SELECT u.*, COUNT(o.id) as order_count FROM users u LEFT JOIN orders o ON o.user_id = u.id WHERE u.created_at > '2024-01-01' GROUP BY u.id ORDER BY order_count DESC LIMIT 10;"
  • "I have a slow query: SELECT * FROM orders WHERE user_id = 123. What’s wrong with it?"
  • “What indexes should I add to improve the performance of my database queries?”

Tips & gotchas

  • This skill focuses on providing optimization suggestions based on EXPLAIN ANALYZE output. It does not automatically apply any changes to your database schema.
  • The effectiveness of index recommendations depends heavily on your specific data and query patterns.
