Failure Patterns Prevented for Pragmatic Rapid Prototyping

Without This Rule (Default LLM Behavior)Vulnerable

When building fast prototypes or MVP products, over-engineering and premature abstraction slow you down. This rule keeps the AI focused on immediate working software.

Hallucination Symptoms
  • Invokes deprecated or removed APIs from older model training weights
  • Generates conflicting configuration files and invalid imports
  • Silently drops type-safety, boundaries, or transaction isolation
With This Rule (Guaranteed Invariants)Deterministic
Prioritize working software over complex design patterns or deep inheritance hierarchies.
Keep code flat, readable, and direct.
Minimize ceremony: avoid multi-file indirection for simple features.
Deliver fast working solutions that can be easily validated or deleted.
04 / REPOSITORY PLACEMENT & 3-STEP TERMINAL INSTALLATION

How to Install Pragmatic Rapid Prototyping OpenAI Custom Instructions via Terminal

1

Step 1: Open Project Directory & Verify Target Placement

Open your terminal and navigate to your project root folder where the prompts/openai-custom-instructions.md file will reside. Ensure the file is placed at the exact path below relative to your project root so the AI engine automatically loads it:

prompts/openai-custom-instructions.md
2

Step 2: Fetch Rule File via Terminal Command

Run curl, PowerShell, or wget to stream the rule directly from the DevScratchpad raw API endpoint and write it to prompts/openai-custom-instructions.md:

Terminal One-Liner Install

Run directly in your project root to stream and write this rule file with one command.

Raw API Stream
$mkdir -p "prompts" && curl -fsSL "https://www.devscratchpad.tech/api/raw/openai-instructions/vibe-coder" -o "prompts/openai-custom-instructions.md"

Step 3: Verify and Activate with AI Agent

Launch your AI coding assistant (Universal AI Assistants). The assistant will automatically discover prompts/openai-custom-instructions.md in your repository and apply the architectural guardrails, type constraints, and verification protocols during code generation.
