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 ovachiever/droid-tings at 7acd12a754.

    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 SQL query optimization patterns to improve database performance. It analyzes existing SQL queries and suggests modifications based on established best practices, such as indexing strategies, query rewriting techniques, and efficient join operations. The goal is to reduce execution time and resource consumption for complex database interactions.

When to use it

  • Slow Query Identification: Use when you've identified a specific SQL query that is taking an unacceptably long time to execute.
  • Performance Tuning: Employ this skill during routine performance tuning exercises for your database systems.
  • Complex Joins: When dealing with queries involving multiple tables and complex join conditions, leverage the skill to optimize join strategies.
  • Large Datasets: Apply it when querying large datasets where even small improvements in query efficiency can yield significant gains.

Key capabilities

  • Query Analysis: Identifies performance bottlenecks within SQL queries.
  • Indexing Recommendations: Suggests appropriate indexes for improved query speed.
  • Query Rewriting: Proposes alternative query structures for better execution plans.
  • Join Optimization: Recommends efficient join algorithms and strategies.

Example prompts

  • "Analyze this SQL query: SELECT * FROM orders WHERE customer_id = 123; and suggest optimizations."
  • "I have a slow query involving tables 'customers', 'orders', and 'products'. Can you recommend indexing strategies?"
  • “Rewrite the following query for better performance: ...[complex SQL query]”

Tips & gotchas

This skill requires access to the SQL query being analyzed. The effectiveness of the recommendations depends on the complexity of the query and the database schema; always test suggested changes in a non-production environment first.
