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 wojons/skills at 5fe7152c66.

    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 optimizes databases to improve performance and efficiency. It analyzes query execution plans, identifies bottlenecks like missing indexes or inefficient table structures, and suggests modifications to enhance overall database speed. The skill aims to reduce query latency and resource consumption for improved application responsiveness.

When to use it

  • Slow Application Performance: When users report slow loading times or sluggish responses from applications relying on a database.
  • High Database Resource Usage: If the database server is consistently consuming excessive CPU, memory, or disk I/O.
  • Complex Queries: When dealing with complex SQL queries that are taking an unexpectedly long time to execute.
  • Database Growth: As databases grow in size and complexity, optimization becomes crucial for maintaining performance.

Key capabilities

  • Query plan analysis
  • Index recommendations
  • Table structure suggestions
  • Bottleneck identification

Example prompts

  • "Analyze the query execution plan for this SQL statement: [SQL Statement]"
  • "Suggest indexes to improve the performance of my database."
  • "Identify bottlenecks in my database that are causing slow queries."

Tips & gotchas

The skill's recommendations should be carefully reviewed and tested in a non-production environment before implementation. Database schema changes can have unintended consequences, so thorough planning is essential.
