postiz is a skill for Claude Code from MoizIbnYousaf/marketing-cli. It costs 159 tokens per session (4,227 once invoked), scanned A, original, MIT.

A publishing tool that sends already-written social posts to many online platforms through a Postiz service. It handles scheduling and publishing; it does not write or adapt the posts.

In plain words
What is it for?
Use it to schedule or publish drafts to platforms such as LinkedIn, Reddit, Instagram, TikTok, YouTube, Discord, and Slack.
Why use it?
It removes the need to publish the same prepared content manually across multiple social networks and helps avoid duplicate retries.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

postiz scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 249 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

Step 1 — Verify the catalog is registered and configured

mktg catalog info postiz --json --fields configured,missing_envs,auth.credential_envs,resolved_base

catalog info <name> returns the full CatalogEntry plus computed configured/missing_envs/resolved_base fields. The command errors with exit code 1 (NOT_FOUND) if the catalog is not in catalogs-manifest.json — that's the "not registered" signal.

  • Exit code 1 → postiz catalog is not registered. Tell the user: mktg catalog add postiz --confirm. Stop.
  • configured: false → env vars are missing. Build the fix string from missing_envs rather than hardcoding. Canonical expectation: POSTIZ_API_KEY (required) and POSTIZ_API_BASE (defaults to https://api.postiz.com if unset; the catalog loader returns resolved_base: null in that case and the skill applies the default). Stop.
  • configured: true → proceed to Step 2.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
