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 anthropics/knowledge-work-plugins at da38ec1ee8.

    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 enables AI agents to generate and install custom plugins specifically designed for the Cowork platform. It streamlines workflow automation by allowing agents to create specialized tools that extend native capabilities within the Cowork environment.

When to use it

  • You need to automate repetitive tasks specific to your organization's Cowork workspace setup.
  • You want to extend standard Cowork features with custom logic or integrations not available out-of-the-box.
  • You are building a specialized AI agent that requires deep access to Cowork data structures and APIs.
  • You aim to deploy reusable automation scripts that other team members can install directly via the platform.

Key capabilities

  • Generates functional plugin code tailored for the Cowork ecosystem.
  • Handles installation procedures for custom plugins within the target environment.
  • Facilitates the creation of domain-specific automation tools without manual coding from scratch.

Example prompts

  • "Create a Cowork plugin that automatically generates weekly performance reports based on team activity logs."
  • "Install a custom plugin to integrate Slack notifications whenever a new project milestone is reached in Cowork."
  • "Build and deploy a tool that syncs task statuses between Cowork and our internal Jira instance."

Tips & gotchas

Ensure your AI agent has appropriate permissions to access the Cowork API before attempting plugin creation. Custom plugins may require specific configuration steps post-installation depending on the complexity of the automation logic defined in the generated code.
