Change a scheduled post

reschedule_post
DestructiveIdempotent

Edit a queued social post before it publishes: change its send time, caption, media, channels, or destination. Only pass the fields you want changed. Already-published posts cannot be edited.

Instructions

Change a post that is still QUEUED — move it to a different time, rewrite the caption, swap the media, add or drop a channel, or change which board / Page / company Page / listing it goes to. PASS ONLY WHAT CHANGES: an omitted field is left exactly as it was, and an explicit empty string CLEARS one (linkedinOrganizationId:"" moves a company-Page post back to the person’s own profile). The edited item is re-checked against the identical rules its create passed — visibility the channel can honour, per-channel length, media the channel can carry — so an edit can never slip past a refusal that a create would have caught. Get the id from list_scheduled. Something that already went out cannot be changed: a published post is edited or removed with manage_meta_post / manage_linkedin_post / delete_x_post, not rescheduled.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
atNothe new time — ISO timestamp (2026-08-05T09:00:00Z) or epoch milliseconds. Must be in the future, at most 365 days out.
idYesthe scheduled post id from list_scheduled
linkNo
pollNoX — replaces the poll; an empty options list removes it.
tagsNoYOUTUBE — replaces the WHOLE tag list; an empty array [] clears the tags.
brandNoWHICH PROFILE this post is in — id or exact name from list_brands; needed when it is not the profile this connection is pinned to. A name that matches no profile, or two, is REFUSED.
eventNoGOOGLE BUSINESS — replaces the whole event record {title, startDate, startTime, endDate, endTime}.
offerNoGOOGLE BUSINESS — replaces the whole offer record {couponCode, redeemOnlineUrl, termsConditions}.
placeNoFACEBOOK — replaces the tagged place (the numeric id of its Facebook Page); an empty string removes it.
storyNoINSTAGRAM — true makes it a 24-hour Story, false an ordinary feed post. One image or one video, no carousel.
titleNoPINTEREST / YOUTUBE — replace the headline; "" clears it and goes back to deriving one from the caption
chatIdNoTELEGRAM — send it to a different chat, group or channel (@username or numeric id). It can be changed but never cleared: telegram cannot publish without one.
ideaIdNoshort id of the content-plan idea this post came from
pageIdNoFACEBOOK / INSTAGRAM / THREADS — publish from a different connected Page (list_meta_pages)
recipeNothe post's FORMAT id, e.g. "slideshow" or "imessage_chat" — post_performance groups by it, so reuse one id per format
threadNoX — replaces the WHOLE thread; an explicit [] drops back to a single post using the caption.
altTextNoACCESSIBILITY — replace the screen-reader description(s). A STRING describes every slide; an ARRAY describes them one at a time in slide order and REPLACES the whole list. "" clears it.
audioIdNoINSTAGRAM REEL — put one of Instagram’s OWN licensed music tracks under the Reel: the `id` search_instagram_audio returns. Instagram mixes it in when the Reel is published; nothing is downloaded or re-rendered. REELS ONLY; an empty string removes it, and only on an Instagram account connected through Meta (a Facebook Page with a linked Instagram), which is Instagram’s own rule — the Instagram connector cannot take it and is refused by name.
boardIdNoPINTEREST — move the Pin to a different board (list_pinterest_boards)
messageNoreplace the caption used for every channel that has no override
audienceNoFACEBOOK — replaces who can see the Page post {countries, regions, cities, minAge}; {} removes the limit.
captionsNoreplaces the WHOLE per-channel caption map — send every override you want to keep, not just the new one
channelsNoreplaces the channel list
coverUrlNoINSTAGRAM REEL — replaces the cover image url; an empty string removes it.
imageUrlNoswap the image; "" removes it
linkNameNoFACEBOOK — replaces the link preview headline; an empty string removes the override.
topicTagNoTHREADS ONLY — one topic tag, without the leading #.
videoUrlNoswap the video; "" removes it
xArticleNoX: replaces the X Article (title, headings); {} makes it an ordinary X post again.
audioNameNoINSTAGRAM REEL — replaces the audio track name; an empty string removes it.
coverAtMsNoTHE VIDEO COVER on every channel, as one frame in milliseconds (see schedule_post).
imageUrlsNoreplace the CAROUSEL slides, in order; an empty array [] drops the carousel and goes back to a single image. Omit to leave the slides exactly as they are. The edited item is re-checked against the same carousel rules the create passed, so adding a channel that cannot swipe is refused now rather than posting slide 1 later.
slideTextNoPINTEREST CAROUSEL ONLY — per-slide title / description / link, aligned to slide order.
topicTypeNoGOOGLE BUSINESS — the kind of Post; EVENT and OFFER both require `event`.
trialReelNoINSTAGRAM — replaces the trial-reel setting on a queued Reel (MANUAL or SS_PERFORMANCE); an explicit "" turns the trial off and it goes out as an ordinary Reel. Only takes effect while the post is still queued — a Reel already published cannot be converted into a trial.
yourBrandNoTIKTOK — the own-brand disclosure; false turns it off.
actionTypeNoGOOGLE BUSINESS — the call-to-action button; "" clears it.
locationIdNoGOOGLE BUSINESS — a different listing (list_business_locations)
madeWithAiNoX — the AI-media label; false turns it off.
visibilityNoNOTE: changing this without also naming visibilityByChannel clears any per-channel overrides, so "make it all draft" is not a no-op
aiGeneratedNoAI-CONTENT DISCLOSURE (Instagram / Facebook Reel is_ai_generated, TikTok is_aigc, YouTube containsSyntheticMedia). OMIT IT and the value already on the post stays; a post that never had one is decided from provenance at publish: a Hermoso render is declared AI-generated, media that came through upload_file or from an external URL (the user’s own photos or footage) is NOT. Pass true or false only to override.
audioVolumeNoINSTAGRAM REEL — how loud that track plays, 0–100 (Instagram’s default 100). Needs audioId.
communityIdNoX — the community to publish into; an empty string goes back to the main timeline.
descriptionNoYOUTUBE — replace the video description; "" clears it and the caption is used.
disableDuetNoTIKTOK VIDEO ONLY — block Duets.
linkPictureNoFACEBOOK — replaces the link preview image url; an empty string removes the override.
quotePostIdNoTHREADS ONLY — the id of the Threads post this one quotes.
shareToFeedNoINSTAGRAM REEL — whether the Reel also shows in the Feed grid.
thumbOffsetNoINSTAGRAM REEL — replaces the cover frame, in milliseconds; 0 removes it. Never together with coverUrl.
videoVolumeNoINSTAGRAM REEL — how loud the video’s own sound plays under the track, 0–100 (Instagram’s default 100; 0 = the track alone). Needs audioId.
callToActionNoFACEBOOK — replaces the button on the Page post; "" removes it.
countryCodesNoTHREADS ONLY — two-letter country codes limiting who can see the post.
optimizeCopyNofit the shared caption to each channel’s own rules when you schedule it (the fitted caption is stored on the scheduled post, so what you scheduled is what publishes) wherever no per-channel caption was written; a channel with its own caption is left exactly as written. Send false to switch it off on this item.
privacyLevelNoTIKTOK — WHICH PRIVACY LEVEL the post goes out at, in TikTok’s own vocabulary. TikTok requires the USER to choose this from the levels their own account allows: call tiktok_creator_info, show them the real options, and pass back the one they picked — never a default and never a guess, which TikTok refuses at init. Omit it and the post falls back to the coarse `visibility` (private -> SELF_ONLY, otherwise PUBLIC_TO_EVERYONE), which cannot express MUTUAL_FOLLOW_FRIENDS or FOLLOWER_OF_CREATOR at all. It must agree with the TikTok visibility (SELF_ONLY is the private one) and it is refused on a TikTok DRAFT, which carries no post info.
replyControlNoTHREADS ONLY — who may reply.
thumbnailUrlNoYOUTUBE: replace the custom thumbnail; "" goes back to a frame of the video, "auto" to YouTube’s pick.
xQuotePostIdNoX — the post this one QUOTES; an empty string removes the quote. Named apart from the Threads `quotePostId` on this same schedule.
collaboratorsNoINSTAGRAM — replaces the WHOLE collab list (up to 3 usernames); an explicit [] removes the co-authors and the post goes out as an ordinary single-author post. Only takes effect if the post has not fired yet — an invite already sent cannot be withdrawn from here.
coverImageUrlNoTHE VIDEO COVER on every channel, as a Hermoso-hosted picture (see schedule_post).
disableStitchNoTIKTOK VIDEO ONLY — block Stitches.
instagramPollNoINSTAGRAM — attach a POLL: 2 to 4 answers of 1–25 characters each, and the caption IS the question (so a caption is required). Feed photos, carousels and Reels only (never a story), one caption add-on per post (not with instagramCommentPrompt), and only on an account connected through Meta (a Facebook Page with a linked Instagram). WRITE-ONCE: Instagram cannot add, change or remove it after publishing, so show the user the answers first.
platformCoverNoVIDEO COVER. Omit it (the default) and Hermoso sets the video’s best frame — the same frame as its Library thumbnail — as the cover on every channel that allows one — and on X, Threads and Bluesky, which have none, a blank first frame is replaced on a copy sent there only. true = send no cover and let the platform pick (usually the first frame). A cover you pass yourself always wins.
replySettingsNoX — who may reply; "" goes back to everyone.
brandedContentNoTIKTOK — the paid-partnership disclosure; false turns it off.
disableCommentNoTIKTOK — comments off on this post.
linkAttachmentNoTHREADS ONLY — a full http(s) URL rendered as a link card on a TEXT-ONLY post. The only way a Threads post carries a destination.
targetAudienceNoLINKEDIN COMPANY PAGE — replaces who sees the post; {} removes the limit. The matching audience must be over 300 followers.
linkDescriptionNoFACEBOOK — replaces the link preview description; an empty string removes the override.
paidPartnershipNoINSTAGRAM AND X — the paid-partnership label; false turns it off.
callToActionLinkNoFACEBOOK — replaces where the button goes; an empty string falls back to the post link.
coverTimestampMsNoTIKTOK VIDEO ONLY — cover frame in milliseconds.
crossreshareToIgNoTHREADS ONLY — also share to Instagram as a Story when it fires; false turns it off. Refused on a carousel.
commercialContentNoTIKTOK — the COMMERCIAL CONTENT DISCLOSURE toggle: true when this post promotes a brand, product or service at all. TikTok requires at least one of yourBrand / brandedContent once it is on, and refuses a post that declares itself commercial without naming which kind. Either disclosure already implies it.
instagramLocationIdNoINSTAGRAM — replaces the tagged place (the numeric id of its Facebook Page); an empty string removes it. Not locationId, which is the Google Business listing.
visibilityByChannelNo
crossreshareDarkModeNoTHREADS ONLY — dark-mode that Instagram Story. Needs crossreshareToIg.
instagramPollExtendedNoINSTAGRAM — give that poll Instagram’s extended voting duration instead of its default 3 days (Instagram’s changelog says it then stays open indefinitely). Only with instagramPoll.
instagramCommentPromptNoINSTAGRAM — make the caption a COMMENT PROMPT that people answer in the comments. Same limits as instagramPoll, and never together with it.
linkedinOrganizationIdNoLINKEDIN — target a different company Page, or "" to post as the connected person instead
brandedContentSponsorIdsNoINSTAGRAM — replaces the sponsor user ids behind the paid-partnership label (at most 2); [] removes them.

TDQS

A4.8/5.0
Behavior5/5

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

Annotations already declare destructiveHint, idempotentHint and openWorldHint, but the description adds substantial behavioral context beyond them: patch semantics (omitted = unchanged, explicit empty string clears, with a concrete linkedinOrganizationId example) and the guarantee that the edit is re-validated against the same create-time rules so it cannot bypass a refusal. This is real disclosure the annotations do not carry.

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-loaded with the core action, then patch semantics, then the validation guarantee, then the exclusion. Dense and nearly waste-free, though the create-time re-validation point is restated in the imageUrls schema description.

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 an 80-parameter mutation tool with no output schema, the description covers the things an agent must know: source of the id, patch/clear conventions, per-channel constraints being re-checked, and the boundary against published-post tooling. Nothing critical to calling it correctly is missing.

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

Parameters4/5

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

Schema coverage is 98% across 80 parameters, so per-field meaning is already documented in the schema and the baseline is 3. The description nonetheless adds a cross-cutting semantic rule (PASS ONLY WHAT CHANGES; empty string/empty array clears) plus examples that govern how every optional field should be interpreted, which is genuine value beyond the schema.

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?

States a specific verb and resource ('change a post that is still QUEUED') and enumerates the dimensions it edits: time, caption, media, channels, board/Page/listing. It explicitly distinguishes itself from post_edit, cancel_scheduled and schedule_post by naming the lifecycle stage it operates on.

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?

Gives explicit when-to-use ('still QUEUED', id comes from list_scheduled) and when-not-to-use ('a published post is edited or removed with manage_meta_post / manage_linkedin_post / delete_x_post, not rescheduled'). The alternative tools are named, so the agent can route without inference.

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