Postify: Drafting Social Posts

Writes a platform-ready social media post and saves it as a Postify draft for a connected LinkedIn, X (Twitter), Instagram, Facebook, TikTok, or other channel, then suggests posting times. Use when the user asks to 'draft a LinkedIn post about our release', 'write a tweet' or a thread, 'prepare an Instagram caption', 'write a launch announcement', 'turn this into a social post', 'create a post for my channels', or 'when should I post this'. Saves drafts only; never publishes.

Draft a post in Postify

Turn the user's idea into a platform-ready draft saved in Postify. The user reviews it in the Postify composer before anything is scheduled or published.

Connecting and calling the tools

Every tool in this skill comes from the postify MCP server, the Postify connector, and is written here as postify:<tool>.

• Tools listed by name: call them directly, for example postify:list_posts.
• Only postify:search_tools and postify:execute_typescript listed (Code Mode, the default): call postify:search_tools first, then call each tool inside postify:execute_typescript as external_<tool> (for example external_list_posts); the program must return its result. Scopes, confirmations and gates are identical on both surfaces.
• "Tool not found": switch to the Code Mode route instead of retrying the direct call. If postify:search_tools does not return the tool either, its OAuth scope was not granted; the user reconnects Postify and approves that scope.
• No postify tools at all: Postify is not connected yet. Install the Postify power, which adds the server; it signs in with OAuth on first use.

Tools you will use

• postify:list_channels: find the channel to target and its platform.
• postify:search_media_library: find an image or video the user already uploaded, when the post needs media.
• postify:suggest_optimal_time: up to three suggested posting times per platform, computed from this workspace's own publish history.
• postify:create_draft: save the post with status draft. Returns the new post id.

Workflow

1. Call postify:list_channels. If the user named a platform with more than one connected account, ask which one.
2. Write the copy for that platform:
   • X: under 280 characters, one idea, no hashtag pile.
   • LinkedIn: hook in the first line, short paragraphs, up to three hashtags at the end.
   • Instagram, TikTok: caption first, hashtags on their own line, mention that media is required.
   • Facebook: conversational, a question or call to action at the end.
3. If media is wanted, call postify:search_media_library with two or three keywords and offer the matches by name. Do not invent media ids.
4. Show the draft to the user and ask for changes once.
5. Call postify:create_draft with the final text, the channel id, and the media id if chosen. Report the post id and that it is saved as a draft.
6. Offer a time: call postify:suggest_optimal_time for the platform and present the suggestions. Scheduling itself happens in the Postify composer or through the managing-content-calendar skill's reschedule step.

Rules

• Never call postify:publish_now. Drafting is the whole job of this skill.
• Do not fabricate links, statistics, or product claims. Ask for the URL when the post needs one.
• Keep the user's voice. If they pasted earlier posts, match their tone and length.
