groups_deleteRemove a group.No findings
Why it is in this group
- The name "groups_delete" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Remove a group. The accounts in it are not touched and stay connected — only the name and its membership go. Posts already scheduled through it are unaffected, because a post records the accounts rather than the group.

- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Remove a file and its stored bytes. This cannot be undone. A file a post still uses cannot be removed, and neither can raw material kept with purpose source: switch it to library with media_save first.

posts_saveCreate, change or cancel a post.No findings
Why it is in this group
- The name "posts_save" says "post": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Create, change or cancel a post. This publishes: a new post is queued for every account named and goes out at scheduled_at, or as soon as possible without one. Do not tell anyone their post is saved or scheduled until this has returned successfully. No post_id creates a post. Name accounts with ids from accounts_list, or a group from groups_list for all of its members — the two combine, and a group is expanded now, so adding an account to it later does not add it to this post. Accounts must all be in one workspace. Attach media by id from media_list; a post is either a video or a set of images, never both. draft true holds it here without sending anything. With post_id, changes a post that has not gone out: caption, time, destinations, or draft state. account_ids and groups then replace the destination list entirely. draft false sends a draft. Setting scheduled_at on a post whose destinations failed queues the failed ones again and leaves the published ones alone — fix what made them fail first, usually by reconnecting. The caption and destinations can only change while nothing has published; after that only the time can, and new words mean a new post. With post_id and cancel true, stops it: destinations that have not started are cancelled, and any already being published cannot be recalled and come back in still_going. Safe to repeat. Publishing has to be enabled on the account; where it is not, a new post saves nothing at all and a draft is left as it was, and the answer says so. Cancelling works whether or not publishing is enabled.

products_deleteDelete a product.No findings
Why it is in this group
- The name "products_delete" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Delete a product. Its accounts stay connected and belong to no product afterwards. Refused while it has campaigns. Its knowledge documents and gathered research are deleted with it, so this is refused while it has any unless confirm_discard is true — read the refusal, which says how many would go, before confirming.

posts_listPosts in your workspaces, newest first, one page at a time, each with the state of every destination it was sent to and the numbers it has earned so far.1 finding
Why it is in this group
- The name "posts_list" says "post": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

What this check looks forMatched text
annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "posts_list" says "post": a word for a change.
Description, as the server wrote it Posts in your workspaces, newest first, one page at a time, each with the state of every destination it was sent to and the numbers it has earned so far. Call it to find one post (post_id), to check whether something published, and before changing or cancelling anything — posts_save takes a post_id from here. Numbers are as of the last sweep, and every destination carries the time it was measured — one nobody has measured yet has no metrics at all rather than zeroes. `trial` names an Instagram trial reel's graduation strategy, and is null for anything that is not one. A trial is shown to non-followers first, so its numbers come from a colder audience than an ordinary post's: compare trials with trials. Each row also carries `insights`: what the platform's own analytics said on that delivery, never summed across deliveries. reach (distinct accounts), totalWatchMs and avgWatchMs, replays, follows (gained from the post), completionRate and skipRate as fractions 0..1, `retention` — the full audience-retention curve as Facebook sends it, `points[i]` being the share still watching at i twentieths of the video and `bucketMs` one twentieth in milliseconds — and `breakdowns` such as clicks by type. retentionAt3s and retentionAtHalf are read off that curve, interpolated between buckets, so hooks can be ranked by how many viewers they held; null without a curve or a known video length. Null means the platform does not report it; a name listed in `unavailable` means it would have and refused this time. Compare watch time across platforms as totalWatchMs / views: Facebook averages per play and Instagram per viewer, so avgWatchMs is not comparable between them. Every filter is optional and they combine: a date range, statuses, platforms, accounts, groups and products by name, where the post came from, and a caption search. Pass nextCursor back as cursor for the next page; null means there is no more.

Changes things 6Claude Code: ask
accounts_connectConnect a social account.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Connect a social account. Opens the platform in the person's browser so they can sign in and approve access — that part cannot happen here, because it needs their session and their consent. Call it again after they finish and it reports the connected account. With `invite`, the link is for someone else instead — a friend or family member who will create a brand-new account and connect it, with no login of their own here. They get a page showing the profile to set up (picture, username, name, bio) with copy buttons, the steps to switch Instagram to a Creator account, and a Connect button. Give the person the `url`. Calling again with the same platform and username returns the same invite, updated with whatever profile fields are given, and its status — so that is also how to check whether they have finished. Upload the profile picture first with media_upload, and pass its id once the PUT succeeds.

groups_saveCreate a group or change one.No findings
Why it is in this group
- The name "groups_save" says "save": a word for a change.
Description, as the server wrote it Create a group or change one. A group is a name for a set of accounts, so posts_save can take the name instead of every id. Found by name without regard to case: an existing group is updated (new_name renames it), and a new name creates one, which needs account_ids. account_ids is always the full membership afterwards, not a list to add. All the accounts must be in one workspace.

media_saveSay what a file is, in your own words.No findings
Why it is in this group
- The name "media_save" says "save": a word for a change.
Description, as the server wrote it Say what a file is, in your own words. description is what it shows: on a base image, who is on camera — "a woman in her early twenties, blonde hair in a loose bun" — and a campaign reads it so the same person appears in every render instead of changing between them. tags are labels to filter by, like sound-effect; metadata is how it was made — provider, model, prompt, jobId, costUsd, sourceUrl, ref, inputs. Each replaces what is there: null clears a description or metadata, [] clears tags. purpose switches a file between library, to post, and source, raw material kept to reuse. For several files at once, items, up to 50: a file not recorded yet comes back in not_found, to save once media_list shows it. Nothing else about a file can be changed here; what it is was read from the file itself.

media_uploadGet a file into ViewPrinter, under an id you can pass to posts_save, media_save or anything else that takes a media id.No findings
Why it is in this group
- The name "media_upload" says "upload": a word for a change.
Description, as the server wrote it Get a file into ViewPrinter, under an id you can pass to posts_save, media_save or anything else that takes a media id. If the person attached the file in this chat, or has it on their phone or computer, call this with no arguments, as an ordinary tool call — not from code, and without trying to send the file yourself. Apps that show widgets put an upload box under the call, which sends the file to ViewPrinter directly even when you have no network access: tell the person to use it. It takes one video or up to ten photos and posts their media ids to the chat, in order, when they are in. Where no box appears, give the person `upload_page`: any device, no sign-in, lasts an hour. Only if you hold the file yourself and can make HTTP requests (a terminal agent, a server), pass kind and mime_type and PUT the bytes to `url` with exactly the `headers` returned. Apps that show widgets never get `url`: the upload box is the way there. Add sha256 (hex) and a file this workspace already has comes back as existing: true, with nothing to upload. If the file is already on the web — a model’s output link, a meme’s direct link — pass from_url instead, with any description, tags and metadata: ViewPrinter fetches it itself and answers fetching: true straight away. It is recorded within minutes; check with media_list and media_id, and if it never appears the link could not be fetched. purpose: source keeps raw material — a generated take, a recording, a sound effect, a saved meme — to find and reuse later. media_list shows it only when asked for purpose source, and it is never posted or used by a campaign as it is. Several files at once: items, up to 50, each as you would pass one; the answers come back in items, in order. Either way the file lands under `id` and is recorded as soon as it arrives. With the box or the page, wait for the person before using it.

products_saveCreate a product, or change one.No findings
Why it is in this group
- The name "products_save" says "save": a word for a change.
Description, as the server wrote it Create a product, or change one. Found by id when given, otherwise by name (ignoring case) and created when there is none, so saving the same product twice changes nothing the second time. account_ids is the complete list of accounts that post for it: accounts in another product move here, and accounts in this one that are not listed leave it. Leave it out to keep the accounts as they are. A product holds accounts from one workspace; when you are in several and name no accounts, pass workspace_id (from accounts_list).

research_askAsk a question about your niche and get back the posts that answer it, from TikTok and Instagram unless platforms narrows it.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Ask a question about your niche and get back the posts that answer it, from TikTok and Instagram unless platforms narrows it. Give question and product_id and it starts searching for that question, which takes a few minutes, and returns at once with a thread_id and status working. Call it again with just the thread_id, about every 15 seconds, until status is ready; then posts are the answer, best first. Each has its URL, caption, hashtags, views, likes, comments, shares and saves, the creator’s follower count, and outperformance: views as a multiple of that creator’s median over the posts we hold of theirs, null when we hold too few. fit says how well a post suits your product (in_niche, adjacent, off_topic) and posts judged off-topic are left out unless you ask for all. A thread takes one question at a time: asking again while it is working does not start a new one. With a failed status, ask the question again. Starting a question uses search credit, so do not repeat one that is working. With neither question nor thread_id it reads what is already indexed, instantly. A post we have watched also carries hook, genre, format and repeatableStructure (null until watched), and a question’s answer gives each post a why: one line on what the video is and how it was judged. The top-level formats and ideas are empty for now.

accounts_listList every social account you can post to, across all your workspaces.No findings
Why it is in this group
- The name "accounts_list" says "list": a word for reading.
Description, as the server wrote it List every social account you can post to, across all your workspaces. Each account includes the workspace it belongs to and any groups it is in. Use the returned ids to name post destinations explicitly, or a group name to name several at once. metrics true adds how each account is performing — followers, posts, total likes and following, each with how far it moved over the period — and orders by followers, largest first. Numbers are as of the last sweep rather than live; every account carries the time it was measured, and one nobody has measured yet has no metrics at all rather than zeroes.

groups_listYour named sets of accounts.No findings
Why it is in this group
- The name "groups_list" says "list": a word for reading.
Description, as the server wrote it Your named sets of accounts. Each group lists its members with the state of each, and how many of them need reconnecting — a post naming a group is refused outright if any member cannot publish, so check here before composing one. Use a group name with posts_save instead of listing account ids.

Why it is in this group
- The name "media_list" says "list": a word for reading.
Description, as the server wrote it Files in your workspaces, newest first, 50 at a time. Use these ids when attaching media to a post. By default these are the files to post; purpose: source lists the raw material kept to reuse instead. Narrow with kind, tags (files carrying every one) or search (words in the description or tags), or pass media_id for one file of either purpose. Each file has a url to download it from. When nextCursor is not null, pass it as cursor for the next page.

Why it is in this group
- The name "platforms_list" says "list": a word for reading.
Description, as the server wrote it What each platform accepts. Called with nothing, it lists every platform with the media kinds and counts it takes and its caption limit — enough to decide where a post can go. Name platforms to add their recommended sizes and durations, their options with what each one does, and the quirks that decide how a post is treated. Read this before scheduling rather than discovering the rules by being rejected.

Description, as the server wrote it The products your accounts post for — an app, a book, a shop — each with the accounts linked to it and the workspace it is in. An account belongs to at most one product. Use products_save to create one or change which accounts belong to it.
