The H2A Manifesto: From Code to Conversation

Two years ago, I couldn't write a single line of code. Today, I orchestrate AI agents.

My journey began not in a computer science classroom, but in the frustrating gap between vision and execution. As a non-programmer entrepreneur, I watched helplessly as my ideas languished in PowerPoint decks and wireframes. Then I discovered what Andrej Karpathy would later call "vibecoding" – and everything changed.

My first creation wasn't built through traditional programming. It was born from conversations with AI, from describing what I wanted rather than how to implement it. No for-loops. No algorithms. Just clear communication with an intelligent system that understood my intent. This wasn't just using AI features – this was treating AI as my development team.

The Great Realization: LLMs Aren't Features, They're Compute Machines

Most founders today sprinkle AI features onto traditional software like seasoning on a meal. They add a chatbot here, some text generation there, and call themselves an "AI startup." They're missing the revolution entirely.

The real paradigm shift isn't in what AI can do – it's in recognizing what AI is.

Large Language Models aren't just clever text generators. They're programmable compute machines that understand natural language as their native instruction set. As Karpathy proclaimed in his June 17, 2025 keynote, "Software Is Changing (Again)" – we've entered the era of Software 3.0, where "the hottest new programming language is English."

Think about this: We spent decades teaching humans to speak to machines in C++, Python, and JavaScript. Now, machines understand us. The implications are staggering.

From Algorithms to Orchestration: The New Development Paradigm

Traditional programming follows a predictable pattern:

1. Define the problem
2. Design the algorithm
3. Write the code
4. Debug until it works

But here's the revolutionary truth: AI agents don't need your algorithms. They create their own.

The new paradigm looks radically different:

1. Define the outcome
2. Provide tools and context
3. Guide the agent
4. Iterate based on results

We've shifted from writing HOW to describing WHAT. From instructing machines step-by-step to empowering intelligent agents with capabilities and letting them figure out the path.

The Employee Analogy: Your AI Development Team

Imagine hiring a brilliant employee. You don't micromanage their every keystroke or dictate each decision. Instead, you:

• Hire the right person (pick the appropriate model)
• Provide tools and resources (MCP integrations, APIs, data access)
• Give clear objectives (well-crafted prompts and contexts)
• Trust their capabilities (let the agent determine the approach)
• Establish feedback loops (iterate based on results)

This isn't anthropomorphism – it's practical reality. When building my first project, I didn't write image processing algorithms. I gave Claude access to image manipulation tools and described what I wanted. The agent figured out how to combine those tools to achieve the desired outcome.

The H2A Recipe: Orchestrating Intelligence

Here's the blueprint we've discovered through countless iterations:

1. Pick Your Model Wisely

Not all LLMs are created equal. Claude excels at complex reasoning and creative tasks. GPT-4 shines in broad knowledge applications. Specialized models handle domain-specific challenges. Choose based on your needs, not marketing hype.

2. Provide MCPs (Model Context Protocols)

This is where the magic happens. MCPs are the universal connectors – the "USB-C of AI apps" as the industry calls them. They let your agents:

• Access external tools and APIs
• Read and write files
• Query databases
• Interact with other systems

Your MCP configuration becomes your agent's capability set. Design it thoughtfully.

3. Craft Your Context

Context isn't just background information – it's the agent's operating manual. Create a CLAUDE.md (or equivalent) that includes:

• System objectives and constraints
• Available tools and their purposes
• Communication protocols
• Success criteria
• Error handling procedures

4. Deploy and Guide

Launch your agent with clear tasks, then guide rather than control. The best results come from collaborative iteration, not rigid instruction.

The Feedback Revolution: Multi-Directional Communication

Traditional software has one-way error messages: "Error 404: Not Found." Helpful, right?

In the H2A paradigm, feedback flows in multiple directions:

• Human → Agent: "This output needs more detail in section 3"
• Agent → Human: "I need clarification on the target audience"
• Tool → Agent: "API rate limit reached, retrying in 60 seconds"
• Agent → Tool: "Attempting alternative approach using cached data"

This rich communication fabric enables true collaboration. Your tools don't just fail – they explain why and suggest alternatives. Your agents don't just execute – they reason, adapt, and improve.

GTUI: The Interface Revolution

We're witnessing the birth of GTUI (GUI + Text User Interface hybrid) – the natural evolution of human-computer interaction. It's neither purely graphical nor purely textual. It's conversational.

In GTUI:

• Natural language drives action: Type what you want, see it happen
• Visual feedback confirms understanding: The interface shows what the agent comprehends
• Contextual controls appear dynamically: Options emerge based on the conversation
• State persists across interactions: The system remembers and builds on previous exchanges

This isn't just a better interface – it's the interface that partial autonomy demands. As Karpathy's "Iron Man suit" analogy suggests, we need interfaces that augment human capability without replacing human judgment.

The Software 3.0 Revolution: Karpathy's Vision Realized

In his groundbreaking June 17, 2025 keynote, Andrej Karpathy outlined the evolution:

• Software 1.0: We wrote explicit instructions in code
• Software 2.0: We trained neural networks on data
• Software 3.0: We converse with AI in natural language

But Karpathy's most profound insight wasn't about the technology – it was about partial autonomy. Drawing from his Tesla Autopilot experience, he described the "autonomy slider" concept: AI systems that users can dial up or down based on trust, context, and need.

"LLMs as operating systems," he called them. Not applications running on an OS, but the OS itself – managing resources, scheduling tasks, handling I/O, and coordinating between multiple processes (agents).

Who This Revolution Is For

MCP Researchers: You're building the infrastructure of the future. Every protocol enhancement, every new connection type, every optimization enables thousands of developers to build what was previously impossible.

Developers in Transition: Your deep technical knowledge isn't obsolete – it's evolving. You understand system design, architecture, and debugging. Now apply those skills to orchestrating intelligent agents rather than writing explicit logic.

Investors Asking "Is It Really an AI Startup?": Here's your litmus test – Does the company treat AI as a feature or as the core compute platform? Are they sprinkling ChatGPT on top, or architecting systems where agents are first-class citizens? The difference determines whether they're building for yesterday or tomorrow.

The Path Forward: Join the Revolution

We stand at an inflection point. The tools exist. The protocols are standardizing. The models are capable. What we need now are builders who understand this paradigm shift.

At H2A.DEV, we're not just building tools – we're redefining the relationship between human creativity and artificial intelligence. We're creating the platforms where:

• Non-programmers ship production software
• Experienced developers orchestrate agent symphonies
• Businesses run on human-guided AI operations
• The boundary between idea and implementation dissolves

Together, we're not just changing how software is built. We're changing who can build it.
