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 mathews-tom/armory at ca902da10b.

    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 SQL queries to improve performance and reduce resource consumption. It analyzes provided SQL statements, identifies potential inefficiencies, and suggests or applies modifications to enhance execution speed. The tool aims to minimize query runtime and overall database load by rewriting complex queries into more efficient forms.

When to use it

  • You're experiencing slow query times in a database application.
  • Database server resource utilization (CPU/memory) is high during peak hours.
  • A developer needs assistance refactoring inefficient SQL code.
  • You want to proactively improve the performance of frequently executed queries.

Key capabilities

  • SQL statement analysis
  • Query optimization suggestions
  • Automated query rewriting
  • Performance improvement recommendations

Example prompts

  • "Optimize this SQL query: SELECT * FROM orders WHERE customer_id = 123 AND order_date > '2023-01-01'."
  • "Can you suggest improvements for this slow-running query?" [followed by the SQL query]
  • “Rewrite this query to be more efficient: ...”

Tips & gotchas

The skill requires a valid SQL query as input. Complex or highly specific database schemas might require manual review of suggested optimizations, as the tool’s effectiveness depends on understanding the underlying data model.
