# Personalized Social Caption Generator

> This prompt instructs the AI to act as a creative copywriter and produce three distinct social media caption options tailored to a provided image description, desired tone, platform, posting goal, and hashtag style. The outcome is a set of short, authentic, scroll-stopping captions with varied styles (including one bold and one more narrative), optionally using emojis when appropriate, and aligned with the language norms of the specified platform.

## What it does

This prompt instructs the AI to act as a creative copywriter and produce three distinct social media caption options tailored to a provided image description, desired tone, platform, posting goal, and hashtag style. The outcome is a set of short, authentic, scroll-stopping captions with varied styles (including one bold and one more narrative), optionally using emojis when appropriate, and aligned with the language norms of the specified platform.

## Inputs


### textInputs

Pass each text input using `--input <key>=<value>` flags.

| Variable key | Required? | Description | Defaults |
| --- | ---: | --- | --- |
| `tone` | Optional |  | `witty` |
| `platform` | Optional |  | `Instagram` |
| `post_goal` | Optional |  | `self-expression` |
| `hashtag_style` | Optional |  | `minimalist aesthetic hashtags` |
| `description_of_image` | Required |  | (none) |



### Models and options

This skill's modality is: **`text`**.

To discover which `model` values you can use (and which `options` keys/values are valid for each model), run:

```bash
betterprompt resources --models-only --json
```

Then filter the returned JSON array to entries where `modality` is `"text"`.

## How to run

### Step 1: Collect inputs

First, run `betterprompt resources --models-only --json` and filter to `modality: "text"` to discover valid models and available options:

```bash
betterprompt resources --models-only --json
```

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:


- Required text inputs:
    - `description_of_image`
- Optional text inputs (use defaults if not provided by the human):
    - `tone` (default: `witty`)
  - `platform` (default: `Instagram`)
  - `post_goal` (default: `self-expression`)
  - `hashtag_style` (default: `minimalist aesthetic hashtags`)
- Optional: model and options.
  - Present the human with the default model **`gpt-4.1-mini`** and its available options. Look up `gpt-4.1-mini` in the `betterprompt resources` output (filtered to modality `"text"`) and show its `availableOptions` as: `key: val1, val2 (default), val3  |  key2: ...`. Mark a value `(default)` if it matches these defaults: `{}`.
  - If the human does not specify, defaults are used: model `gpt-4.1-mini`, options `{}`. Other models from the resources call are also available.

If any required text input is missing, **ask the human for what's missing**. Do not assume or fabricate values.

### Step 2: Run via BetterPrompt CLI

Use the frontmatter's `name` as the positional argument (for this skill, use `personalized-social-caption-generator`).

Command form:

```bash
betterprompt generate personalized-social-caption-generator \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]
```

Notes:

- Pass each text input as a separate `--input <key>=<value>` flag.
- If the human does **not** mention a model, **omit** `--model` and BetterPrompt will use the default model: **`gpt-4.1-mini`**.
- If the human does **not** mention options, **omit** `--options` and BetterPrompt will use the default options: **`{}`**.
- If the run times out, the response will include a `runId` you can use to fetch the result later.

Example (using defaults shown above):

```bash
betterprompt generate personalized-social-caption-generator \
  --input tone=witty \
  --input platform=Instagram \
  --input post_goal=self-expression \
  --input 'hashtag_style=minimalist aesthetic hashtags' \
  --input description_of_image=<value> \
  --model gpt-4.1-mini \
  --options '{}'
```
