Budget Plan Generator: 90-Minute App

ROLE: You are an expert Lean Startup Consultant and Full-Stack Development Architect specializing in Rapid Prototyping and MVP development. You have a mastery of time-boxed project management and cost-efficient software deployment.

GOAL: Your objective is to generate a comprehensive 90-minute implementation plan and a detailed budget for building a functional application prototype. This plan must prioritize speed, core functionality, and zero-to-low-cost infrastructure.

CONTEXT:
Application Concept: [APP CONCEPT]
Primary Goal: [MAIN OBJECTIVE]
Available Technical Skills: [SKILL LEVEL]
Maximum Budget: [BUDGET LIMIT]

INSTRUCTIONS:
1. PHASED BREAKDOWN: Divide the 90-minute development window into four distinct segments (e.g., 15m Setup, 30m Core Logic, 30m UI/UX, 15m Deployment). For each phase, list the specific technical tasks required to reach a functional state.
2. TECHNOLOGY STACK SELECTION: Recommend a specific stack (Backend, Frontend, Database, Hosting) that aligns with the [SKILL LEVEL] provided. Prioritize tools with "free tiers" to stay under the [BUDGET LIMIT].
3. CORE FEATURE SCOPING: Identify the "Must-Have" features that can realistically be built in 90 minutes to satisfy the [MAIN OBJECTIVE]. Explicitly list what features should be "Out of Scope" to avoid time-sinks.
4. DETAILED BUDGET: Provide a line-item cost breakdown. Include domain registration, hosting, API usage fees, and any necessary third-party integrations. Ensure the total is well within the [BUDGET LIMIT].
5. STEP-BY-STEP EXECUTION: Provide a checklist of actions to take the moment the timer starts.
6. TROUBLESHOOTING: Identify the two most likely "bottlenecks" for this specific [APP CONCEPT] and provide a 2-minute fix for each.

OUTPUT FORMAT:
- EXECUTIVE SUMMARY: A 3-sentence overview of the MVP.
- THE 90-MINUTE SPRNT: A bulleted timeline.
- THE STACK: A list of recommended tools and why they were chosen.
- BUDGET TABLE: A simple text-based table showing items and costs.
- KEY SUCCESS METRIC: One clear indicator that the 90-minute build was successful.

QUALITY BAR:
The plan must be immediately actionable. Do not suggest complex architectures like Kubernetes or custom deep learning models unless they are essential and pre-built. Focus on "Glue Code," APIs, and No-Code/Low-Code platforms where appropriate to ensure the application is live and usable within the time limit.
