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 wshobson/agents at 46891e7e60.

    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

The vector-index-tuning skill optimizes vector index configurations to improve search performance and accuracy in AI systems that rely on embeddings. It enables users to fine-tune parameters like indexing strategies, dimensionality settings, and similarity metrics for better retrieval outcomes.

When to use it

  • When you're experiencing slow query response times with your vector database.
  • When you need to enhance the precision of search results from an embedding model.
  • Before deploying a production system that requires efficient and accurate vector searches.

Key capabilities

  • Fine-tuning indexing strategies (e.g., IVF, HNSW).
  • Adjusting similarity metrics (e.g., cosine, dot product).
  • Optimizing dimensionality for better performance.
  • Configuring index parameters like quantization or compression levels.

Example prompts

  • "Optimize my vector index for faster search with a 768-dimensional embedding model."
  • "Adjust the similarity metric to use dot product instead of cosine similarity."
  • "Tune the HNSW index configuration for better recall at scale."

Tips & gotchas

  • Ensure your embeddings are normalized before tuning, as this can significantly impact performance.
  • Some tuning parameters may require reindexing, which could be resource-intensive on large datasets.
