Automated safety checks

scanned

This skill failed 1 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: zernio.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.

    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.

About this skill

What it does

This skill provides guidance and assistance for interacting with the Late API, enabling AI agents to schedule posts across 13 social media platforms. The API allows developers to programmatically manage profiles, connect accounts via OAuth (including Bluesky app passwords and Telegram bot tokens), create and schedule posts, and access analytics data. The base URL for the API is https://zernio.com/api/v1 and documentation can be found at zernio.com/docs.

When to use it

  • Automating social media posting schedules across multiple platforms.
  • Connecting new social media accounts to a scheduling system.
  • Retrieving analytics data for YouTube daily views or LinkedIn performance.
  • Managing queued posts and configuring slots within the API.
  • Troubleshooting errors related to publishing or authentication.

Key capabilities

  • Scheduling posts across 13 platforms (Twitter/X, Instagram, Facebook, LinkedIn, TikTok, YouTube, Pinterest, Reddit, Bluesky, Threads, Google Business, Telegram, Snapchat).
  • OAuth account connection flows.
  • Management of API keys and authentication.
  • Access to platform-specific data and limitations.
  • Webhook configuration and signature verification.
  • Media upload functionality with presigned URLs.

Example prompts

  • "Create a post for Twitter/X, Instagram, and Facebook with the content 'Hello!'."
  • "Connect my Twitter account using OAuth."
  • "What are the supported media formats for YouTube posts?"
  • "Show me the error codes related to publishing failures."

Tips & gotchas

  • You will need a valid API key (YOUR_API_KEY) to interact with the Late API.
  • Refer to the rule files (e.g., rules/authentication.md, rules/posts.md) for detailed documentation on specific functionalities and limitations.
  • OAuth flows require additional steps beyond simple API calls, as indicated in the rules/connect.md file.
