Workflow

Example: schedule a post from the terminal

A short session that drafts, reviews and schedules one post for two networks.

1. Draft

List my SimplePost accounts. Draft a post announcing our 2.4 release for LinkedIn, and a shorter version for Bluesky under 300 characters. Save it as one draft.

Result: One draft with a Bluesky override is saved and both versions are printed.

2. Schedule

Schedule the draft for Thursday 14:00 Europe/Paris.

Result: The post is scheduled; Gemini CLI reports the exact time.

Publishing details

What Gemini CLI can do

Use the SimplePost skill's publishing rules in Gemini CLI sessions.
List accounts, save drafts, preview and schedule posts.
Read your SimplePost calendar and manage scheduled posts.

Connect social accounts in the SimplePost web app. Engagement analytics and changes to already published posts stay on the social network.

Different versions for each network

Per-account overrides keep the LinkedIn and Bluesky versions in the same post, so they are scheduled and reported together.

Sign-in and permissions

The extension uses OAuth with the hosted server. Gemini CLI checks the authorization server's issuer on the callback, which SimplePost includes.
The token is stored by Gemini CLI and survives restarts; it expires after 90 days.

Publishing actions and tools

What Gemini CLI can do at each stage
Preview	preview_post and show_post_preview return the preview as text in the terminal.
Schedule	create_post with a scheduled time.
Publish now	create_post in now mode.
View scheduled posts	get_schedule and inspect_posts.
Update or cancel	update_scheduled_post and discard_scheduled_post.

If something does not work

The extension is not listed
