## Short answer

**Can Claude Cowork turn a rough Instagram brief and a folder of images into drafts?**

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.

## Example: a bakery chain prepares its autumn campaign

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.

## Step by step

1. **Share the brief, the brand guide and the folder.** 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.
2. **Sign off a refined brief first.** 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.
3. **Match images through the media library.** 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.
4. **Write two options per image.** 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.
5. **Save the best pairs as drafts.** 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.
6. **Request slots and approve them.** 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.

## Prompts to copy

### Refine the brief

```text
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. Point out every place where the brief and the guide disagree. Do not write captions yet.
```

### Match and write

```text
Use Tareno to find the approved images in my media library and match them to the refined brief. 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.
```

### Save the chosen pairs

```text
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.
```

### Request the weekend slots

```text
Ask Tareno to schedule drafts [IDs] for [Saturday 09:00 and Sunday 09:00] in the [Europe/Berlin] time zone. Return the pending action IDs and remind me that nothing is published until I approve them in the Tareno dashboard.
```

## Instagram in Tareno

- Tareno's configuration requires media for Instagram, so every caption in the plan has to be tied to a file from your library; a caption without an image cannot become a post.
- Tareno takes alt text of up to 1,000 characters per media item, and Instagram's documentation lists alt text for image posts, so ask for it with each caption.
- Instagram's documentation says API publishing works for professional accounts. Connect the chain's professional account in Tareno before the task starts.
- Captions can be up to 2,200 characters, and hashtags and mentions are supported, so a seasonal campaign can add a local hashtag without hitting the limit.

Official rules ([Meta: Instagram Platform, content publishing](https://developers.facebook.com/docs/instagram-platform/content-publishing), checked 2026-10-24):

- API publishing is limited to Instagram professional accounts. If the account is linked to a Page that requires Page Publishing Authorization, it cannot publish until that authorization is complete.
- A carousel can hold up to 20 images or videos, mixed. Tareno's own composer configuration lists up to 10 images per Instagram post.
- Alt text sent through the API applies to image posts only; reels and stories do not support it.

## Mistakes to avoid

- Skipping the refined brief and going straight to captions. Fixing a wrong assumption in one page is faster than fixing it in twelve drafts.
- Sharing an unapproved image folder. Cowork matches whatever it sees, so remove images with unclear rights before the task begins.
- Treating the two caption options as final. They are starting points; read them aloud once, because tone mistakes are easy to hear and hard to see.
- Using a brand guide that is out of date. Tell Cowork which document wins when the brief and the guide disagree.

## What does not work

- Claude Cowork cannot judge brand fit or image rights, so every image and caption pair needs your own confirmation before you approve a slot.
- It cannot upload images from your computer into Tareno on its own, so files must already be in the media library or reachable at a public HTTPS address.
- It cannot publish a post itself, because scheduling and publishing requests become pending actions in the Tareno dashboard.

## Frequently asked questions

### Can Claude Cowork turn a messy brief into a usable Instagram plan?

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.

### Why refine the brief before writing captions?

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.

### Can Cowork choose which image belongs to which caption?

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.

### Does Claude Cowork write alt text for Instagram images?

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.

### Will a Cowork task publish my posts?

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.

### Do I need to set up anything for each Cowork task?

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.

## Tareno tools used

- `list_media`
- `create_drafts`
- `get_action_status`

Approval model: Tareno saves drafts directly. Scheduling, publishing, edits to scheduled posts and deletions become pending actions that a person approves in the Tareno dashboard; no agent can approve them.
