Publish a post

create_post

Publish to Instagram, Facebook, TikTok, YouTube or X. This posts publicly unless the platform's privacy setting says otherwise, so confirm the content with the user first. post is exactly the JSON body of POST /api/v1/posts: Instagram takes image or images (base64), with altText and userTags per image and collaborators and isAiGenerated per post (hashtags go in caption); Facebook takes image, images, reel or video (base64); TikTok takes video (prefer {"url": "https://..."} over base64) or photos, with music_usage_confirmed: true. Call get_tiktok_creator_info before a TikTok post. TikTok videos publish publicly (privacy_level PUBLIC_TO_EVERYONE or omitted); any other video privacy_level is refused. Photos take any level from get_tiktok_creator_info. post_mode MEDIA_UPLOAD sends a draft to the creator's TikTok inbox instead of publishing. YouTube takes video (prefer {"url": "https://..."}), title, privacy_status (public, unlisted or private) and made_for_kids, all required; ask the user for privacy_status and made_for_kids rather than choosing them. publish_at schedules a private video to go public. Until Adeli passes YouTube's API audit, YouTube keeps every upload private: the result says so with privacyRestricted. X takes text (280 characters, a link counts as 23) and media: up to 4 images, or 1 GIF, or 1 video, as base64 or a video {"url"}; thread is a list of further posts, each a reply to the one before. Every X post is billed at X's price ($0.015, or $0.20 with a link), and a thread that fails part-way returns 207 with the posts that went live. TikTok, Facebook and YouTube video publish asynchronously: poll get_tiktok_post_status, get_facebook_post_status or get_youtube_post_status with the returned publishId. Multipart uploads are REST-only.

  2. First observed

TDQS

A4.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations cover only the safety profile (readOnlyHint=false, openWorldHint=true, destructiveHint=false). The description adds far more: public-by-default posting, async publish for TikTok/Facebook/YouTube with polling, X billing ($0.015, $0.20 with a link), a 207 partial-failure return for threads, and YouTube's privacyRestricted behavior until the API audit passes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the essential purpose and the public-posting warning before platform detail, and nearly every sentence carries unique operational facts. It is nevertheless a dense wall of text with no structural breaks, which makes it harder to scan than it could be for a tool this complex.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a multi-platform, multi-shape mutation tool with no output schema, the description supplies the async polling contract, the partial-failure code, billing, platform privacy constraints, and the TikTok preflight dependency. Nothing an agent needs to invoke it correctly appears to be missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% on a deeply nested anyOf, so the description carries the full burden and does so: per-platform payload shapes, Instagram altText/userTags/collaborators/isAiGenerated, Facebook image/images/reel/video, TikTok music_usage_confirmed:true and post_mode, YouTube required title/privacy_status/made_for_kids, and X text limits (280 chars, link = 23) plus media/thread rules.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a precise verb+resource ("Publish to Instagram, Facebook, TikTok, YouTube or X") and enumerates exactly which platforms are supported. An agent can immediately distinguish it from list_posts, get_*_status and the update_* siblings without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent: "Call get_tiktok_creator_info before a TikTok post," "poll get_tiktok_post_status / get_facebook_post_status / get_youtube_post_status with the returned publishId," and "ask the user for privacy_status and made_for_kids rather than choosing them." It also states the precondition "confirm the content with the user first" and notes multipart uploads are REST-only.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
