Once a universal code execution environment becomes the standard 'super tool' for AI agents, creating new capabilities will no longer require custom code. Instead, 'building a tool' will mean writing a detailed prompt that instructs the LLM on how to sequence actions using an already-exposed, comprehensive API SDK.
Contrary to belief that intuitive AI will kill prompt engineering, OpenAI's president argues it will become more potent. As models handle basic context, the same effort from a skilled prompter will yield far greater results, raising the ceiling on what's achievable and creating a bigger multiplier effect.
The key skill for building is shifting from mastering no-code tools like Webflow and Zapier to working with AI agents. This represents a new programmable layer of abstraction where proficiency is defined by prompting, context management, and systems thinking for AI, not visual development.
Complex prompting is a transitional phase for AI interaction, not the end state. Truly useful AI tools will abstract this complexity away, using agents to translate user intent into optimal prompts. The focus should be on creating intuitive, directorial controls rather than teaching users to be prompt engineers.
The process of building AI tools is becoming automated. Claude features a 'Skill Creator,' a skill that builds other skills from natural language prompts. This meta-capability allows users to generate custom AI workflows without writing code, essentially asking the AI to build the exact tool they need for a task.
Instead of giving an LLM hundreds of specific tools, a more scalable "cyborg" approach is to provide one tool: a sandboxed code execution environment. The LLM writes code against a company's SDK, which is more context-efficient, faster, and more flexible than multiple API round-trips.
The next step for agentic AI is a 'cyborg' model. Instead of juggling numerous pre-defined tools, the LLM will have one primary tool: a code execution environment. It will write code against a company's SDK to perform tasks, which is more flexible, faster, and context-efficient than traditional tool calling.
The focus in AI has shifted from crafting the perfect prompt (prompt engineering) to providing the right information (context engineering), and now to building the entire operational environment—tooling, systems, and access—that enables a model to perform complex tasks. This new paradigm is called harness engineering.
Platforms like Trajectory RL are creating marketplaces for AI "skills" — applications written in plain text, not code. This signals a paradigm shift where the next software layer for AI agents will be built on natural language instructions rather than traditional programming.
The most leveraged engineering activity is creating a 'meta-prompt' that takes a simple feature request and automatically generates a detailed technical specification. This spec then serves as a high-quality prompt for an AI coding agent, making all future development faster.
To avoid the rapid depreciation of hard-coded systems as LLMs improve, Blitzy's architecture is dynamic. Agents are generated just-in-time, with prompts written and tools selected by other agents based on the latest model capabilities and the specific task requirements.
