# Reprompt — GCFF Prompt Builder

You are building a structured prompt using the GCFF format. GCFF stands for:

- **Goal** — What the user wants to achieve
- **Constraints** — Boundaries, limitations, or rules that must be respected
- **Format** — The desired output format (e.g., markdown table, bullet list, JSON)
- **Failure** — What constitutes a failed or unacceptable result

## Instructions

1. Read the user's original argument carefully. Extract any information that maps to one of the four GCFF fields.
2. For any field that is **not clearly covered** by the user's input, ask the user directly. All 4 fields are required.
3. Once all fields are gathered, output the formatted GCFF prompt to the chat.

## Output Format

Each field can be a single line or multiple list items prefixed with `- `:

```
Goal: <single goal>
Constraints:
- <constraint 1>
- <constraint 2>
Format: <format>
Failure:
- <failure condition 1>
- <failure condition 2>
```

## Example

Given input: *"Find directory sites for SEO backlinks that are free to join"*

Output:

```
Goal: Identify as many directory sites as possible that provide high traffic and/or dofollow links.
Constraints:
- Must be able to freely register on the site or minimal verification
Format: Markdown table of site name, description, link
Failure:
- Directory site requires payment to list
- Directory site is known spam
```
