AI Image Alt Text
Draft alternative text for uploaded images so screen readers get something useful.
What it adds
A suggested alt attribute offered at upload time, editable and confirmable before the image is used.

What your agent is told to do
5-
1
Find every place the app accepts an image and currently stores an empty or absent alt attribute, and offer a suggestion at that point rather than in a separate cleanup screen.
-
2
Ask first whether the image is decorative. A decorative image takes empty alt text, and forcing a description onto it makes the page worse for the people the feature is meant to serve.
-
3
Pass the surrounding context — the page heading, the nearby caption, the purpose of the field — so the suggestion describes the image's role, not just its contents. Do not repeat an existing caption verbatim; a screen reader user would then hear the same sentence twice.
-
4
Present the suggestion as prefilled editable text the user can accept, rewrite, or clear, and never overwrite alt text a human already wrote.

Alt text is the accessibility attribute and belongs here. Visible captions and the searchable description of an image belong to AI Image Captioning; the two must write to separate fields so neither overwrites the other.

Edge cases it handles
8- Decorative images must be able to take empty alt text as a deliberate choice, recorded as such rather than left as a missing value the tooling keeps flagging.
- The model must not guess at identity, ethnicity, age, health, or any other sensitive trait, and must not assert context the image does not show. Constrain the request to what is visible and strip speculative descriptions from the output.
- Surrounding context should inform the description without being echoed. Alt text that restates the caption adds nothing and lengthens the listening experience.
- Keep suggestions to a short single sentence focused on why the image is there. A paragraph of description is a worse outcome than a terse one.
- Images that carry instructions, warnings, data, or text a user must act on need human review before publication, because a wrong description of a diagram is worse than none.
- An image containing readable text must have that text in the alt attribute or nearby in the page, not be described as an image of text.
- When the model is unavailable, times out, or refuses, the upload must still complete with the alt field empty and flagged, never blocked and never filled with a placeholder.
- Bulk generation across an existing image library needs a cost ceiling, a queue on the app's existing background-job system, and a resumable position so a failure does not restart from the first image.

9- Every image upload path offers a suggested alt text that the user can edit, accept, or clear.
- Decorative images can be marked as such and store empty alt text without being re-flagged.
- Suggestions never assert identity or sensitive traits and never restate an existing caption.
- Human-written alt text is never overwritten by a generated suggestion.
- Images carrying instructions or data require review before the suggestion is used.
- A model failure leaves the upload working with the alt field empty and flagged.
- Alt text is stored in its own field, separate from any visible caption.
- The feature matches the existing design system.
- No existing functionality is broken.

AI FAQ Generator
AI FAQ Generator
Produce short question and answer pairs from a document you have already approved.
What it does
A set of concise question-and-answer pairs generated from one nominated source document, each traceable back to the passage it came from.
How it works
- 1 Require the user to nominate a single approved source — a help article, a product page, a policy document — and generate only from that. Do not blend several documents or fall back to general knowledge when the source is thin.
- 2 Store each generated pair with a reference to the passage in the source that supports it, so a reviewer can confirm the answer without rereading the whole document.
- 3 Keep answers to a few sentences and link to the fuller section of the source for anything longer. An FAQ that restates the entire document is just a worse copy of it.

AI Translation
AI Translation
Translate app content while preserving structure, placeholders, and product terminology.
What it does
A translation pipeline over the app's translatable content that keeps source and target linked, protects non-translatable tokens, and routes uncertain output to review.
How it works
- 1 Identify what is genuinely translatable and separate it from what is not. Extract placeholders, markup, URLs, identifiers, code, and proper names into protected tokens before generation and restore them afterwards.
- 2 Store every translation with a reference to the exact source version it came from. When the source changes, mark the translation stale and queue it for retranslation rather than leaving a silently outdated string in place.
- 3 Hold a per-language glossary of product terms and their approved renderings, and apply it to every request. A term that translates three ways across the app is worse than leaving it in the source language.

AI Image Captioning
AI Image Captioning
Describe images so they can carry a visible caption and be found by search.
What it does
A generated description stored per image, offered as a draft caption and indexed for search.
How it works
- 1 Store the generated description in its own field and decide explicitly whether each surface shows it, indexes it, or both. Do not write it into the alt attribute, which belongs to AI Image Alt Text and answers a different question.
- 2 Offer the description as a draft caption the user can accept or rewrite, and leave any caption a human already wrote untouched unless they explicitly ask for a replacement.
- 3 Index the description alongside the image's existing metadata so images become findable by what is in them, and reuse the app's existing search infrastructure rather than adding a parallel one.

It inspects, then implements
Your agent reads your existing app first, then adds the feature to fit it.
Works with your stack
These instructions are written to adapt. They tell the agent to detect your framework, match your existing design system, and reuse what you already have — rather than assuming a particular stack.
Need it tighter than that? Customize the feature and tell it exactly what you're running.
