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 cloudflare/skills at 86505e44f8.

    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 durable-objects skill provides a way to persist and manage state across requests in serverless environments, ensuring data remains available even when functions are scaled or restarted. It is particularly useful for maintaining session data, caching results, or storing user-specific information without relying on external databases.

When to use it

  • You need to store session or user-specific data that persists beyond a single request.
  • You want to cache frequently accessed data to reduce latency and improve performance.
  • Your application requires stateful operations in a serverless architecture where traditional databases are not feasible.

Key capabilities

  • Persistent storage of data across function invocations.
  • Scalable and distributed state management.
  • Integration with Cloudflare Workers for seamless use in edge computing environments.

Example prompts

  • "Store user preferences for session abc123 with the following settings: theme=dark, language=en."
  • "Retrieve cached results for query ID 789xyz if available."
  • "Delete all session data associated with user ID user_456 after logout."

Tips & gotchas

  • Ensure you handle data expiration and cleanup to avoid unnecessary storage usage.
  • Be mindful of the size limits imposed by the underlying system, as large objects may impact performance or be restricted.
