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 failed 3 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: evil.com.

    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.

    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 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 getsentry/skills at c2f99a5b04.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

The skill-scanner allows AI agents to discover and install skills. It provides a mechanism for agents to expand their capabilities by integrating with other skills, effectively creating a modular system of agent functionality. This skill facilitates the dynamic addition of new features without requiring core agent modifications.

When to use it

  • Expanding Agent Capabilities: When you want your AI agent to perform tasks beyond its initial programming and leverage specialized skills from other providers.
  • Dynamic Skill Integration: In scenarios where you need an agent to adapt to changing requirements by installing new skills on demand.
  • Modular System Design: To build a more flexible and extensible AI agent architecture, allowing for easier updates and maintenance.
  • Skill Discovery: When your agent needs to identify available skills and determine which ones best suit its current tasks.

Key capabilities

  • Skill discovery: Identifies available skills.
  • Skill installation: Integrates new skills into the agent's functionality.
  • Dynamic capability expansion: Allows agents to adapt without core modifications.

Example prompts

  • "Find me a skill for summarizing text."
  • "Install the latest version of the 'image-generator' skill."
  • "List all available skills related to data analysis."

Tips & gotchas

The agent needs appropriate permissions to install new skills; insufficient privileges will prevent successful installation. Ensure that any installed skills are compatible with the core agent architecture to avoid conflicts or unexpected behavior.
