Post to X (Twitter) from OpenClaw

OpenClaw can publish tweets, threads, and X Community posts through the Postiz skill. You message OpenClaw from a chat app such as WhatsApp or Telegram, describe the post, and it calls the Postiz CLI to upload media, set who can reply, and schedule the tweet at the time you asked for.

# Confirm OpenClaw can see the skill

How Postiz Becomes an OpenClaw Skill

When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose X posts with the right settings.

✓Install from ClawHub with one command: openclaw skills install @nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Run openclaw skills check to confirm the postiz binary and credentials are in place
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Install from ClawHub

# Install the Postiz skill from ClawHub
openclaw skills install @nevo-david/postiz

# Or with the skills CLI
npx skills add gitroomhq/postiz-agent

# Sign in with OAuth2 (or set POSTIZ_API_KEY)
postiz auth:login

# Verify OpenClaw sees it

Scheduled & Proactive

openclaw automations for recurring content

OpenClaw automations run on cron expressions in an isolated session and can announce results to a chat channel. Create one that drafts and schedules your X content through Postiz, so nothing waits on a manual trigger.

openclaw automations (cron)

openclaw automations create "0 9 * * 1-5" \
  "Read ~/content/tweets, schedule one X post for noon, let everyone reply, then move the file to ~/content/posted." \
  --name "X daily post" \
  --session isolated \
  --announce --channel telegram \
  --to "<your chat id>"

# openclaw cron is an alias for the same command

Why OpenClaw + Postiz for X

OpenClaw's skill system makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for X workflows.

✓Message from WhatsApp to post a tweet — no terminal needed
✓Cron jobs for hands-free daily posting schedules
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Thread creation handled automatically with multiple content flags
✓Cross-post to X + other platforms in a single conversation
✓Model-agnostic — works with Claude, GPT, Gemini, or open-source LLMs

Also Works with Claude Code

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code, which has its own guide for posting to X from Claude Code.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your X integration, composes your tweet or thread, applies reply settings, and schedules the post.

Claude Code

> Post a thread about our product launch
  on X, schedule for tomorrow, everyone
  can reply

Claude: Done! Scheduled on X for
  tomorrow at 9:00 AM.

X + Other Platforms

Schedule the same content to X and other platforms in a single request. Each platform gets its own settings.

Example

> Post "Excited to announce our new feature!" to
  X and LinkedIn tomorrow at 9am, then schedule
  a daily tip on X every weekday at 10am

OpenClaw: Done! Scheduled:
  - X + LinkedIn: tomorrow 9:00 AM
  - Daily tips on X: Mon-Fri 10:00 AM

What can you ask OpenClaw to do on X?

These are real messages you can send OpenClaw from WhatsApp, Telegram, Slack, or Discord. OpenClaw maps each one to the right Postiz command and X settings.

X rules OpenClaw has to follow

Postiz enforces these X constraints when OpenClaw creates a post. Knowing them up front avoids a failed request.

✓Standard X accounts are limited to 280 characters per tweet. Ask OpenClaw for a thread when your text runs longer and Postiz posts each part as a reply in order.
✓who_can_reply_post is required. If you do not mention reply settings, OpenClaw should default to everyone, so say "followers only" or "verified only" when you want a restriction.
✓Community posting needs the full community URL. OpenClaw cannot look up a community by name, so paste the link into your message.
✓Each tweet can carry up to four images or one video. Upload media through Postiz first, or just attach it in the chat and ask OpenClaw to include it.

OpenClaw and X: frequently asked questions

How do I post to X from OpenClaw?

Install the Postiz skill with openclaw skills install @nevo-david/postiz, sign in with postiz auth:login, and connect your X account in Postiz. Then message OpenClaw from any connected chat app with the tweet text and a time. It runs postiz posts:create with the X settings and confirms the schedule.

Can OpenClaw post a thread on X?

Yes. Ask for a thread and OpenClaw sends the first tweet as the post body and the rest as ordered comments. Postiz publishes them as native replies, so the thread appears exactly as if you wrote it by hand. Each part can have its own image or video.

Can OpenClaw control who replies to my tweets?

Yes. X exposes the who_can_reply_post setting through Postiz with five values: everyone, following, mentionedUsers, subscribers, and verified. Say the option in plain language, for example "only people I follow can reply", and OpenClaw applies the matching value before scheduling the post.

Does OpenClaw need the X API directly?

No. OpenClaw never touches the X API. It runs the Postiz CLI, and Postiz holds the OAuth connection to your X account. You authenticate OpenClaw once with postiz auth:login or a Postiz API key, and there is nothing to configure on the X developer portal.

Can OpenClaw post to X on a schedule without me?

Yes. Create an OpenClaw automation with a cron expression, for example weekdays at 9am, and give it a prompt that reads your drafts folder and schedules an X post through Postiz. The job runs in an isolated session and can announce results back to your chat channel.
