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 aj-geddes/useful-ai-prompts at 3f5182cfd7.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill enables AI agents to generate optimized database indexing strategies tailored to specific query patterns and data volume constraints. It assists in reducing query latency and improving overall system performance by recommending appropriate index types, such as B-Trees or Hash indexes, based on workload analysis.

When to use it

  • Optimizing slow queries: When specific SELECT statements are executing slower than expected due to full table scans.
  • Scaling read-heavy workloads: Before deploying a database that will handle high volumes of frequent lookups or filtering operations.
  • Reducing storage overhead: When analyzing trade-offs between index size and query speed to prevent bloat in large datasets.
  • Designing new schemas: During the initial architecture phase to ensure data retrieval paths are efficient from day one.

Key capabilities

  • Analyzes SQL query patterns to identify missing or inefficient indexes.
  • Recommends specific index structures (e.g., B-Tree, Hash, Composite) based on data distribution.
  • Evaluates the impact of indexing on write performance and storage requirements.
  • Generates migration scripts for adding or removing indexes safely.

Example prompts

  • "Analyze these top 5 slowest queries from our production logs and suggest an optimal indexing strategy to reduce latency."
  • "We are building a read-heavy analytics dashboard; recommend index types that will speed up aggregation queries without significantly impacting write throughput."
  • "Generate a plan to optimize our PostgreSQL database for frequent range scans on the created_at column while minimizing storage growth."

Tips & gotchas

  • Indexing is not always beneficial; ensure you analyze write-heavy workloads first, as excessive indexes can degrade INSERT and UPDATE performance.
  • Always validate recommendations with actual load testing in a staging environment before applying changes to production databases.
