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 pluginagentmarketplace/custom-plugin-postgresql at 8a52bc4cd9.

    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 foundational knowledge and capabilities for interacting with PostgreSQL databases. It allows agents to execute SQL queries, retrieve data, and understand basic database concepts. The skill enables tasks like querying customer information, generating reports from sales data, or managing inventory records within a PostgreSQL environment.

When to use it

  • Data Retrieval: When an agent needs to extract specific information from a PostgreSQL database, such as product details or user profiles.
  • Report Generation: To create simple reports based on data stored in the database (e.g., monthly sales summaries).
  • Database Management: For performing basic administrative tasks like checking table structures or verifying data integrity.
  • Data Analysis: To perform initial analysis of a dataset, such as identifying trends or outliers.

Key capabilities

  • SQL query execution
  • Data retrieval from PostgreSQL databases
  • Basic database concept understanding

Example prompts

  • "Show me all customers in the 'California' region."
  • "What were the total sales for last month?"
  • "Describe the structure of the 'products' table."

Tips & gotchas

  • Requires access to a PostgreSQL database and appropriate credentials.
  • The skill focuses on fundamentals; more complex database operations may require additional skills or custom scripting.
