social-scheduler-extended

What This Skill Does

The social-scheduler-extended skill serves as a robust, direct-to-API bridge between your OpenClaw agent and the Postiz social media management platform. Unlike workflows that rely on middleware like n8n, this integration communicates directly with your self-hosted or cloud-based Postiz instance to handle the complete social media lifecycle. It empowers your agent to manage over 28 distinct social channels, including major players like X, LinkedIn, Bluesky, Reddit, and Instagram. The skill handles content adaptation for platform-specific character limits, media uploads from local files or URLs, deduplication logic to prevent spam, and thread construction for long-form content. By managing the state of posts—ranging from DRAFT and QUEUE to PUBLISHED and ERROR—it ensures your agent maintains a reliable and consistent publishing cadence without manual intervention.

Installation

To integrate this capability into your agent, use the OpenClaw command-line interface. Open your terminal and execute the following command:

clawhub install openclaw/skills/skills/coolmanns/social-scheduler-extended

Ensure that you have your Postiz API credentials and instance URL ready, as you will need to authenticate the session by generating a session cookie via the /api/auth/login endpoint before the agent can successfully execute posting commands.

Use Cases

This skill is ideal for content marketers, growth hackers, and social media managers who want to automate their presence across multiple networks. Use it to:

• Automate the repurposing of blog posts into platform-specific updates (e.g., professional tone for LinkedIn, punchy updates for X).
• Maintain a 24/7 social media calendar by querying for the next available time slots per channel.
• Programmatically generate X/Twitter threads for educational content or complex announcements.
• Sync media assets from a repository to various social networks with a single agent command.
• Monitor and update the status of scheduled posts, allowing the agent to reactively handle errors or reschedule missed content.

Example Prompts

1. "Check the next available time slot for my LinkedIn and X accounts, then schedule a post announcing our new AI feature with the image at https://example.com/feature.png."
2. "Draft a 3-part thread for X about the benefits of local AI agents, using the content in my project documentation, and queue it for tomorrow morning."
3. "List all scheduled posts for the next 7 days and delete any that are marked as 'ERROR' to clear the queue."

Tips & Limitations

• Authentication: Keep in mind that the authentication cookie expires. Configure your agent to re-run the login routine if it encounters 401 Unauthorized errors.
• Character Limits: While the skill provides data on character limits, always instruct your agent to use a 'summarize' or 'truncate' tool if your input text exceeds the platform-specific constraints, especially for X (280 chars) and Bluesky (300 chars).
• Media: Always validate that URLs are publicly accessible, as the Postiz API needs to fetch the file to upload it to the platform's servers. If you are uploading local files, ensure the agent has read access to the directory.
