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 obsessiondb/clickhouse-skills at 1305d7ad25.

    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 assists in designing ClickHouse schemas. It can generate schema definitions based on provided data structures or descriptions, ensuring efficient storage and querying within a ClickHouse database. The skill aims to optimize for performance and resource utilization when defining tables and their associated columns.

When to use it

  • You need to create a new ClickHouse table but are unsure of the optimal column types and structure.
  • You're migrating data from another system and require assistance translating the schema into ClickHouse format.
  • You want to refactor an existing ClickHouse schema for improved query performance or reduced storage costs.
  • You’re building a new data pipeline that requires defining ClickHouse tables to store processed information.

Key capabilities

  • Schema generation from descriptions
  • Optimization for ClickHouse performance
  • Column type selection guidance
  • Table structure design

Example prompts

  • "Create a ClickHouse schema for storing website clickstream data, including timestamp, URL, and user agent."
  • "Design a table to store product catalog information with columns for ID, name, description, price, and category."
  • "Suggest an efficient ClickHouse schema for time series data with sensor readings every minute."

Tips & gotchas

The quality of the generated schema depends heavily on the clarity and completeness of your input descriptions. Be as specific as possible about the data you intend to store and any performance requirements.
