Automated safety checks

scanned

This skill failed 2 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 3 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: api.x.com, developer.x.com, docs.x.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.

About this skill

What it does

This skill allows an AI agent to retrieve user profile information from X (formerly Twitter) using a username or ID. It fetches details like display name, handle, bio, follower count, verification status, account creation date, and more. The skill requires setting up an API token for authentication before use.

When to use it

  • Find contact information for someone on X when you only have their username.
  • Verify the authenticity of a user's account (e.g., checking for verification status).
  • Gather basic profile details about individuals mentioned in text or conversations.
  • Quickly access public metrics like follower counts to gauge influence.

Key capabilities

  • Retrieves user profiles by username or ID.
  • Provides fields including: id, name, username, description, public_metrics, verified, created_at.
  • Requires an X API bearer token for authentication.

Example prompts

  • "Find the profile information for kurtwuckertjr."
  • "What is the username and bio of this user?" (followed by providing a user ID)
  • "Get me the verification status and follower count for [username]."

Tips & gotchas

  • API Token Required: You must set the X_BEARER_TOKEN environment variable with your X API bearer token, obtained from the developer dashboard (https://developer.x.com/en/portal/dashboard), before using this skill.
  • Execution Path: The skill is executed via a shell script located at ${CLAUDE_PLUGIN_ROOT} /scripts/lookup.sh. Ensure that path is accessible to your AI agent.
  • Rate Limits: Be mindful of X API rate limits; excessive use may result in temporary restrictions.
