How Postiz Works with Hermes Agent

Postiz ships as an agent skill in the agentskills.io SKILL.md format that Hermes Agent reads. The skill documents every Postiz CLI command, the credentials it needs, and the YouTube settings, so Hermes knows how to list your channels, upload media, and create posts without any custom code.

✓Install the Postiz CLI (npm install -g postiz) and add the skill with npx skills add gitroomhq/postiz-agent
✓Hermes loads skills from ~/.hermes/skills and shows them with hermes skills list
✓Authenticate with POSTIZ_API_KEY, or run postiz auth:login for an OAuth device flow
✓Every Postiz command returns JSON, so Hermes can chain discovery, upload, and posting
✓Prefer MCP? Add https://mcp.postiz.com/mcp-oauth-dynamic under mcp_servers in ~/.hermes/config.yaml

Install Postiz

# Install the Postiz CLI and skill
npm install -g postiz
npx skills add gitroomhq/postiz-agent

# Authenticate: API key or OAuth device flow
export POSTIZ_API_KEY=your_api_key
# or: postiz auth:login

YouTube rules Hermes Agent has to follow

Postiz validates every YouTube post before it is scheduled, so these limits and required settings decide whether a request succeeds.

▸YouTube requires a video file. The post content becomes the video description, and title is a separate required setting of 2 to 100 characters.
▸Visibility (type) is required: public, unlisted, or private. Say which one you want or Hermes will ask.
▸Custom thumbnails must be uploaded with postiz upload first, then referenced by id and path.
▸Tags are value/label pairs. Long tag lists count against YouTube's 500-character total tag limit.
