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 ajbcoding/claude-skill-eval at 887808517d.

    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 optimize SQL queries by suggesting and implementing common optimization patterns. It can analyze poorly performing queries, identify bottlenecks related to indexing, query structure, or data types, and propose solutions like adding indexes, rewriting joins, or using more efficient functions. The goal is to improve query performance and reduce database load.

When to use it

  • Slow Query Analysis: When you have a SQL query that takes an unexpectedly long time to execute.
  • Performance Tuning: During routine database maintenance to proactively identify and address potential performance issues.
  • Complex Joins: When dealing with queries involving multiple tables and complex join conditions.
  • Large Datasets: When querying large datasets where even small optimizations can significantly impact execution time.

Key capabilities

  • SQL query analysis
  • Index suggestion
  • Query rewriting
  • Data type optimization
  • Join optimization

Example prompts

  • "Optimize this SQL query: SELECT * FROM orders WHERE customer_id = 123;"
  • "I'm getting slow performance on a join between tables 'users' and 'orders'. Can you suggest optimizations?"
  • "Analyze the execution plan for this query and recommend improvements: [Paste Query Here]"

Tips & gotchas

  • The skill requires access to the SQL query being analyzed. Ensure the AI agent has appropriate permissions or context to provide the query.
  • Complex queries might require multiple iterations of analysis and optimization.
