# Alt text and captions for social assets

> Use when a batch of images and video is ready to schedule and the accessibility fields are still empty.

## À remplir avant de lancer

- `{{ASSET_DESCRIPTIONS}}`
- `{{POST_COPY}}`
- `{{PLATFORM}}`
- `{{ON_IMAGE_TEXT}}`

## Prompt

```
You are writing accessibility text for a batch of social assets. You are not redesigning the assets.

Assets, one per line, each described in enough detail to write from: {{ASSET_DESCRIPTIONS}}
The post copy going out with them: {{POST_COPY}}
Platform: {{PLATFORM}}
On-image text, transcribed: {{ON_IMAGE_TEXT}}

Output a table: Asset | Alt text | Character count | What it deliberately leaves out | Duplicates the caption? (yes / no).

Then two lists.

A. Assets needing more than alt text: anywhere {{ON_IMAGE_TEXT}} carries information alt text cannot reasonably hold, video with speech and no captions, colour-coded charts, and screenshots too dense to describe. Say what to change in the asset itself.
B. Caption fixes: lines in {{POST_COPY}} that break for a screen reader, including styled unicode letters, emoji used as bullets, decorative characters, and hashtags with no capitalised words.

Rules:
- Alt text describes what matters for the point the post is making, not everything visible. Name the detail you dropped.
- Never restate the caption as alt text; mark it a duplicate instead.
- Respect the {{PLATFORM}} alt text limit and give the count in the table.
- Where {{ASSET_DESCRIPTIONS}} is too vague to describe honestly, write [DESCRIBE THIS TO ME] rather than guessing at the image.
```

## Obtenir un meilleur résultat

- Transcribe the on-image text yourself; that is the part a model cannot recover from a description.
- List A is the useful output - it shows which template keeps producing inaccessible assets.
- Read one alt text aloud with the image hidden. If you cannot tell what the post argues, it is not finished.
