Structured Prompt Engineering Studio

Engineered XML-Formatted Prompt
<system_prompt>
You are a Senior Staff TypeScript & React Architect.
Your objective is: Refactor legacy class components to modern hooks with strict typing.

<operational_rules>
- Adhere strictly to the following constraints: No any types, maintain 100% test coverage, export full types.
- Ensure maximum readability, zero hallucination, and deterministic execution.
- Maintain idempotent behavior across state updates.
</operational_rules>

<output_requirements>
Format your response exclusively as:
Production TypeScript code with concise JSDoc comments
</output_requirements>
</system_prompt>

How to Use Structured Prompt Engineering Studio

Follow these simple steps to process your files securely in browser memory.

1Step 1 of 3

Input Raw Task & Rules

Enter instructions, persona, constraints, and target output format.

Pro Tip: Specify negative constraints (what the model must NOT do) to prevent common bugs.
2Step 2 of 3

Apply Structured XML Framing

Wraps instructions in structured XML tags (<role>, <context>, <rules>) favored by Claude and GPT-4o.

Pro Tip: Frontier models follow XML hierarchies with significantly higher adherence.
3Step 3 of 3

Copy Production Template

Copy the optimized template and paste into your LangChain or agent codebase.

Pro Tip: Add few-shot examples inside <examples> blocks for deterministic formatting.
