Choosing the Right AI Tools for Your Development Workflow Code smarter, not harder AI Tools for Developers: Prototyping vs. Coding How to AI Coding tools boost your productivity 

How AI can help you try out ideas in minutes • Try out ideas with simple prompts • Incorporate existing design systems using Figma or screenshots • Create full-stack applications with backend functionality like authentication, storage, and serverless functions Code smarter, not harder Agentic Prototyping: AI-Driven PoC’s How to AI Coding tools boost your productivity 

I want to create a web app that helps me generate social media posts. I should be able to authenticate myself to securely access my account. Once I’m logged in, I want to enter a topic into a free-text field. The app should then fetch current sources related to that topic using the Perplexity API. Based on these sources, it should use the ChatGPT API to generate relevant, engaging, and reach-optimized social media posts. All generated posts should be persistently saved in a database and linked to my authenticated user account. Code smarter, not harder How to AI Coding tools boost your productivity 

In 10 minutes Code smarter, not harder How to AI Coding tools boost your productivity 

Full-stack applications with a user-friendly approach • User friendly interface for nontechnical users • Uses React • Chat mode to plan before act • Strong Supabase integration for authentication and databases • 3rd Party integrations like Stripe, Resend or OpenAI • Optimized for team collaboration with GitHub- first workflows Code smarter, not harder Tool Spotlight: Lovable.dev How to AI Coding tools boost your productivity 

Self hosted full-stack application prototyping • Based on bolt.new • Runs locally on your device using Docker • In browser Visual Studio Code environment • Can connect to any LLM provider or local running LLMs with Ollama • Supports any web framework or Node based backends Code smarter, not harder Tool Spotlight: bolt.diy How to AI Coding tools boost your productivity 

The Benefits and Limitations of AI-Assisted Development • Fast PoC development – Reduces time from idea to prototype • No Local Setup Needed – Tolls running in the browser • Immediate Visual Feedback – preview UI changes in real-time • Supabase Integration – Strong backend setup in Lovable • Collaboration Features – Lovable integrates well with GitHub • AI costs and token limits – usage is often billed per token or message • AI-generated code requires manual refinement – quality varies depending on prompts and models. • Vendor lock-in – code can be shared between tools • Limited framework support (mostly React) Code smarter, not harder AI-Driven Prototyping: Pros & Cons Pros Cons How to AI Coding tools boost your productivity 

How AI Automates, Refactors, and Optimizes Code • Add tools by plugins or use an AI-Coding IDE • Pretend architecture & tech stack details by providing rules • Use different LLM models and begin prompting • Use images & documentations to add current knowledge • Add external context using MCP-Servers • Use the agent mode or the chat to plan or act • Develop features or refine existing code as needed Code smarter, not harder From Prototype to Production: AI Coding Agents in Action How to AI Coding tools boost your productivity 

The all-inclusive AI Coding toll • Can be used accross multiple IDEs (VS-Code, IntelliJ, Xcode etc.) • Free to use / 10$ per month for the pro version • Provides ask, edit and agent mode • Inline autocompletion, code reviews and test generation • Povides different LLMs (GPT, Gemini, Sonnet, etc.) • MCP (Model Context Protocol) support Code smarter, not harder Tool Spotlight: GitHub Copilot – Edit/Agent Mode How to AI Coding tools boost your productivity 

Why coding tools fail to support you • LLMs were trained on older data • LLMs don’t understand your architecture without help • LLMs don’t know your company domains • LLMs don’t know your coding standards • Developers don’t write prompts describing every edge case or needed context to solve tasks • Different tasks require different context Code smarter, not harder Limitations of LLMs How to AI Coding tools boost your productivity 

Simplify your prompts • Project-specific coding standards • Architectural patterns and constraints • Domain knowledge embedding • Step-by-step reasoning requirements How to generate?: • Ask the AI to analyze your codebase • Use predefined instructions • Iterateive update your instructions Code smarter, not harder Fighting Back - Custom Instructions How to AI Coding tools boost your productivity 

AGENTS.md • The problem: each tool uses different file names for custom instructions • AGENTS.md aims for becoming supported by all AI tools • Supported by: Cursor, GitHub Copilot, Aider and more Code smarter, not harder Standardization of Custom Instructions How to AI Coding tools boost your productivity 

Override the default System Prompt • Create agents for specific tasks • Define supported tools, MCP-Servers and LLM- Models • Run reusable prompts for reusable workflows How to AI Coding tools boost your productivity Code smarter, not harder Custom Chat Modes 

The key for ”intelligent” workflows • Open-source protocol developed by Anthropic • Provides a consistent way for LLMs to interact with external resources • Client-Server architecture: AI applications (clients) request context from external services (servers) • Official servers are available for GitHub, Atlassian, Playwright, Stripe, Databases and more • It’s the key to useful AI-coding setups in complex environments Code smarter, not harder Model Context Protocol (MCP) How to AI Coding tools boost your productivity 

Developer asks: “Explain failing tests in PR #42.” Copilot calls GitHub MCP → fetches PR diff + CI log LLM reviews context → returns root-cause & fix steps Dev clicks “Apply fix” → Copilot edits code & opens new PR Code smarter, not harder MCP workflows How to AI Coding tools boost your productivity 

• Not all LLMs are equal: Performance varies widely • Understand reasoning vs. non-reasoning models • Context size matters greatly in coding scenarios • Benchmarks help guide practical model choice • Cost per 1 million input/output tokens Code smarter, not harder Choosing the right LLM for your tasks How to AI Coding tools boost your productivity
