+description: Agent-driven scheduling and publishing of social media posts across 13 platforms via SocialClaw. Use when the user wants to publish to X, LinkedIn, Instagram, Facebook Pages, TikTok, Discord, Telegram, YouTube, Reddit, WordPress, or Pinterest — or when managing campaigns, uploading media, or monitoring post delivery status.

+
+# Social Publisher (SocialClaw)
+
+Connects Claude Code to [SocialClaw](https://getsocialclaw.com) for agent-driven social media publishing across 13 platforms through a single workspace API key.
+
+## When to Activate
+
+- publish content to X, LinkedIn, Instagram, TikTok, or other platforms
+- schedule a post campaign across multiple platforms at once
+- upload media for use in social posts
+- validate a post schedule before going live
+- monitor publishing run status and delivery analytics
+
+## Setup
+
+```bash
+# Required: workspace API key from https://getsocialclaw.com/dashboard
+export SC_API_KEY="<workspace-key>"
+
+# Verify access
+curl -sS -H "Authorization: Bearer $SC_API_KEY" https://getsocialclaw.com/v1/keys/validate
+
+# Install CLI (optional but recommended)
+npm install -g socialclaw@0.1.12
+socialclaw login --api-key <workspace-key>
+```
+
+## Core Workflow
+
+### 1. List connected accounts
+```bash
+socialclaw accounts list --json
+```
+
+If not connected:
+```bash
+socialclaw accounts connect --provider x --open
+socialclaw accounts connect --provider linkedin --open
+```
+
+### 2. Upload media (optional)
+```bash
+socialclaw assets upload --file ./image.png --json
+# → { "asset_id": "..." }
+```
+
+### 3. Build schedule.json
+```json
+{
+  "posts": [
+    {
+      "provider": "x",
+      "account_id": "<account-id>",
+      "text": "Post text here",
+      "scheduled_at": "2026-06-01T10:00:00Z"
+    }
+  ]
+}
+```
+
+### 4. Validate before publishing
+```bash
+socialclaw validate -f schedule.json --json
+```
+
+### 5. Publish
+```bash
+socialclaw apply -f schedule.json --json
+# → { "run_id": "..." }
+```
+
+### 6. Monitor
+```bash
+socialclaw status --run-id <run-id> --json
+socialclaw posts list --json
+```
+
+## Supported Providers
+
+| Provider | Key |
+|----------|-----|
+| X (Twitter) | `x` |
+| LinkedIn profile | `linkedin` |
+| LinkedIn page | `linkedin_page` |
+| Instagram Business | `instagram_business` |
+| Instagram standalone | `instagram` |
+| Facebook Page | `facebook` |
+| TikTok | `tiktok` |
+| YouTube | `youtube` |
+| Reddit | `reddit` |
+| WordPress | `wordpress` |
+| Discord | `discord` |
+| Telegram | `telegram` |
+| Pinterest | `pinterest` |
+
+## Security
+
+- Outbound requests go to `getsocialclaw.com` only
+- Provider OAuth is in the SocialClaw dashboard — no per-provider secrets exposed to the agent
+- `SC_API_KEY` is a workspace-scoped key
+
+## Related Skills
+
+- `x-api` — direct X/Twitter API operations
+- `social-graph-ranker` — network analysis for outreach targeting
+
+## Source
+
+- npm: `npm install -g socialclaw@0.1.12`
+- Dashboard: https://getsocialclaw.com/dashboard
