×Hand Claude Cowork a rough content brief, approved assets and brand rules; it tightens the brief, pairs captions with images and saves Instagram drafts in Tareno.
Yes. Claude Cowork reads the brief, the brand rules and the approved images you share, tightens the brief into a few clear lines, writes two caption options per image and saves the best pairs as Instagram drafts through Tareno. It cannot judge brand fit on its own, and a scheduling request stays pending until you approve it in Tareno.

Most Instagram briefs arrive as a long email, a few photos and a sentence like "make it feel warm". The slow part is not writing captions; it is turning that mess into rules a caption can follow. Claude Cowork is built for jobs that work through several files, so it can read the brief, the brand guide and the image folder together, produce a refined brief you can sign off and only then write. This page follows a bakery chain's seasonal campaign, from the unclear brief to drafts waiting for review, and shows where Cowork helps and where a person has to decide.
Suppose a bakery chain wants six posts for its pumpkin-loaf season. The marketing assistant shares a Cowork task with the brief email, a two-page brand guide and a folder of eight approved photos. Cowork first returns a one-page refined brief: audience, tone in three adjectives, words to avoid, the call to action and which photo suits which message. The assistant corrects two lines, and Cowork then asks Tareno for list_media to match filenames, writes two captions per photo and saves the chosen pairs through create_drafts. It returns a table of draft IDs, files and captions. The brand manager compares picture and text side by side in Tareno and requests Saturday and Sunday slots, which wait as pending actions until she approves them.
Give Cowork everything in one task: the brief as it arrived, the brand rules and the list of approved images. A task that sees all three can notice when the brief and the guide disagree.
Ask for a one-page version of the brief before any caption exists: audience, tone, words to avoid, call to action and image-to-message mapping. You correct the brief in minutes, instead of correcting twelve captions later.
Cowork calls list_media and pairs filenames with messages. If an image in the folder is not in your Tareno library yet, it says so, and you upload it before drafts are saved.
Ask for two captions per photo in different registers, for example playful and informative. Two options keep the final choice with you without extra rounds of rewriting.
Cowork saves the chosen image and caption pairs through create_drafts for the Instagram account you name, and returns a table of draft IDs, files and captions.
Give dates, times and an IANA time zone. Requests become pending actions, and you approve them in the Tareno dashboard; get_action_status tells you the outcome later.
Read the attached brief, the brand guide and the list of approved images [file names]. Return a one-page refined brief with the audience, three tone adjectives, words to avoid, the call to action and the message each image should carry.

Write two caption options per image, one playful and one informative, each under 2,200 characters. Show them in a table with the filename and do not save anything yet.I choose the following options: [list]. Save these image and caption pairs as Instagram drafts for [account name] through Tareno and return a table with draft ID, file and caption so I can compare them in the dashboard.Ask Tareno to schedule drafts [IDs] for [Saturday 09:00 and Sunday 09:00] in the [Europe/Berlin] time zone.

list_accountsChecked:
Yes. Cowork reads the brief, the brand guide and the approved images together and returns a one-page refined brief for your sign-off. Only after that does it write captions, which keeps corrections cheap and the result consistent.
A wrong assumption in the brief spreads into every caption. A one-page brief with audience, tone, words to avoid and the call to action can be corrected in minutes, and the captions that follow inherit the correction.
It proposes pairs from the message of each caption and the filenames and descriptions you provide. It cannot judge brand fit, so you compare picture and text in Tareno before you request a slot.
Yes, if you ask. Tareno accepts alt text of up to 1,000 characters per media item, and Instagram's documentation lists alt text for image posts, so it improves accessibility for a carousel or a single image.
No. Scheduling and publishing requests become approval actions in Tareno. Nothing reaches Instagram until you approve them in the dashboard, and Cowork can only report the pending state or read the result later.
Only once. After the Tareno plugin is installed and you have signed in, later tasks can use it. For each task, say which account, which assets and which documents to use so that the result lands on the right profile.
