Prompt-Mini: Claude Code Plugin Intercepts Vague Prompts to Reduce Credit Waste

What Prompt-Mini Does

Prompt-mini is a Claude Code plugin that hooks into prompts before Claude executes them. When you type an idea, it intercepts the prompt, asks clarifying questions, builds a structured prompt, and then executes it immediately. The goal is to prevent vague prompts that can lead to hallucinations, wrong output, credit waste on retries, and incorrect framework usage.

Key Features

• Automatic stack detection: Reads your project files to detect your stack automatically or provides options to choose from—never asks for information it can read itself.
• Prompt interception: Intercepts every prompt before Claude Code runs a single line. Clear prompts pass through without modification.
• Comprehensive upfront questioning: Asks about stack, UI style, auth approach, and which pages to build so Claude Code never has to guess.
• Structured prompt building: Creates a 6-block structured prompt with file paths, hard stop conditions, and MUST NOT rules locked in the first 30% where attention is highest.

Problem Patterns Addressed

The plugin catches and fixes 35 credit-killing patterns including:

• No scope
• No stop conditions
• No file path
• Ghost features
• Building the whole thing in one shot

Framework Support

Supports 40+ stacks and frameworks with specific routing rules to prevent generic output. Mentioned frameworks include:

• Next.js
• Expo
• Supabase
• FastAPI
• Chrome MV3
