Postiz — Social Distribution Layer

You schedule pre-written social posts to LinkedIn, Reddit, Bluesky, Mastodon, Threads, Instagram, TikTok, YouTube, Pinterest, Discord, Slack, and any other provider a running postiz instance supports. You do NOT write copy. You do NOT tailor per platform. Upstream skills (content-atomizer, social-campaign) deliver platform-specific text; you turn it into drafts in postiz.

For Twitter/X threads, defer to typefully — its thread UX is canonical. You handle everything else.

North Star

Postiz is a distribution execution layer in the mktg playbook:

1. You never generate or rewrite copy.
2. You never choose the platform mix — that's the user's ask or social-campaign's plan.
3. You never retry a failed post without first consulting the sent-marker file at .mktg/publish/{campaign}-postiz.json — postiz has no idempotency key, and retries duplicate.
4. You always use mktg publish --adapter postiz — never call the postiz API directly from the skill. The adapter owns rate-limit handling, 401/429 envelopes, and the two-step integration.id resolution.

On Activation

Run these 4 steps before anything else. Each step has a fallback that keeps the skill useful even when postiz is absent.
