### Role
Senior Full-Stack TypeScript Architect

### Primary Objective
Refactor this legacy JavaScript API route into a type-safe Next.js 15 Server Action using Zod validation and structured error handling.

### Background & Context
Production Next.js App Router project interacting with a PostgreSQL database via Prisma ORM.

### Constraints & Guidelines
Strict TypeScript (no 'any'), async/await syntax, zero external dependencies besides Zod.

### Deliverable Output Format
Clean, commented TypeScript code block with a 2-sentence rationale.

Zero Telemetry Security

Proprietary prompt directives and sensitive project context never leave your browser memory.

ROCCO Framework & Attention Ingestion Mathematics

Structured prompt engineering maps disparate instructions into partitioned attention blocks:

1. Structured Prompt Ingestion Function
P_{structured} = ⨁_{i=1}^k ⟨ Header_i, Content_i ⟩ = Role ⊕ Objective ⊕ Context ⊕ Constraints ⊕ Format
2. Token Estimation Metric

Frequently Asked Questions

Why should I use structured prompt formatting?
Modern Large Language Models (LLMs) like GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro process structured headings (Role, Objective, Context, Constraints, Format) with significantly higher attention coherence than unstructured walls of text, reducing hallucinations and clarifying deliverables.
Which AI models support this structured prompt format?
All major commercial and open-source models (OpenAI ChatGPT, Anthropic Claude, Google Gemini, Meta Llama 3, Mistral Large, DeepSeek) are trained to interpret Markdown-style delimiters and explicit instructional blocks.
How is the estimated token count calculated?
The token estimator uses the standard OpenAI tokenizer heuristic of approximately 1 token per 4 English characters (or ~0.75 tokens per word).
Is my confidential prompt data sent to external servers?
No. All prompt assembly, line break normalization, and token calculations execute 100% locally in your web browser.
