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 tursodatabase/turso at 64b8ef5742.

    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 mvcc skill provides Multi-Version Concurrency Control (MVCC) capabilities, allowing AI agents to manage concurrent database transactions efficiently. It ensures data consistency and isolation by maintaining multiple versions of records, enabling read operations to proceed without blocking writes.

When to use it

  • When handling high-concurrency database environments where multiple users or processes access the same data simultaneously.
  • During transaction processing that requires consistent reads while allowing writes to occur in parallel.
  • In applications needing snapshot isolation to prevent dirty reads and ensure reliable query results.

Key capabilities

  • Supports concurrent read and write operations without blocking.
  • Maintains historical versions of records for consistency during transactions.
  • Provides snapshot isolation levels for reliable data access.

Example prompts

  • "Implement MVCC in the database to handle concurrent user updates."
  • "Ensure that reads do not block writes by using multi-version concurrency control."
  • "Set up a transaction system with snapshot isolation using the mvcc skill."

Tips & gotchas

  • Ensure your database engine supports MVCC for compatibility.
  • Be mindful of storage overhead due to maintaining multiple record versions.
