From Coding Newbie to Agent Builder: A Journey of Creating a Leaderboard-Cracking AI

2026-05-02 21:54:13

In a world where AI agents are taking over tasks, even the world's worst coder decided to jump on the bandwagon. This is the story of a complete coding novice who set out to build an agentic system—not for fame or fortune, but to crack a leaderboard at work. Along the way, they grappled with steep learning curves, unexpected bugs, and moments of surprising triumph. Here's what they learned about building an agent, and about coding itself, through a series of questions and answers.

What exactly does it mean to 'go agentic' as a coder?

Going agentic means creating an AI system that can autonomously perform tasks without constant human input. For this project, the goal was to build an agent that could logically search for strategies, parse data from leaderboards, and even attempt to 'crack' or outsmart that leaderboard—all without the author having to manually code every step. The catch? The builder was a self-professed 'worst coder', so the agent had to be simple yet powerful, often relying on pre-built libraries and lots of trial and error. The reward was seeing the agent slowly learn and improve, much like a novice coder's own skill set.

What challenges did the world's worst coder face when building an AI agent?

The biggest challenge was understanding the very basics. The coder didn't know how to structure code, handle errors, or even effectively use an IDE. Building an agent required grasping concepts like decision trees, API calls, and feedback loops. Initially, the agent would fail at simple tasks—like reading a leaderboard's HTML—because the coder hadn't accounted for inconsistent web structures. Debugging was a nightmare: every error message felt like a foreign language. Another hurdle was avoiding over-engineering. The coder wanted to add advanced features like natural language processing, but quickly realized that a simpler, rule-based agent was more achievable. The constant need to google basic syntax and break down problems into micro-steps was both frustrating and educational.

How did the agent actually 'crack' the leaderboard?

The agent wasn't 'cracking' in a malicious sense; rather, it systematically analyzed the leaderboard's scoring rules to find optimal patterns. For example, if points were awarded for completing tasks within a time limit, the agent would simulate different execution strategies to minimize time. It used a combination of web scraping to fetch current standings, a simplistic decision engine that ranked possible actions, and automated scripts to perform those actions. The coder described it as 'brute-force with a dash of logic'. Over several iterations, the agent learned which strategies yielded higher scores, and eventually the coder's name started climbing the leaderboard. The 'cracking' was really about optimization and understanding the system's weaknesses—a lesson in algorithmic thinking.

What were the unexpected rewards of building this agent?

Beyond the thrill of seeing a rank improve, the novice coder discovered a deep sense of ownership. Every bug fixed, every feature added—even if copied from Stack Overflow—felt like a personal victory. The agent became a mirror of the coder's learning: as the coder got better, the agent got smarter. Another reward was the community feedback. Colleagues were surprised that a self-proclaimed coding newbie could produce a working agent. This boosted confidence and opened conversations about AI. Most importantly, the coder learned that building with an agent is an iterative process—you don't need to be an expert to start, you just need to keep going. The project transformed fear of coding into a playful, curious attitude.

What coding lessons did the author learn through this agentic project?

The biggest lesson was the importance of breaking down problems. Instead of tackling 'build a leaderboard-cracking agent', the coder learned to split it into chunks: scrape data, analyze scores, test strategy, and automate. Each chunk required learning a micro-skill—using requests for APIs, BeautifulSoup for parsing, and simple if-else logic for decisions. The coder also grasped that debugging is not failure but a part of the process. Every error taught them something new about syntax, data types, or API limits. Finally, they realized that documentation is your friend. Reading library docs became less intimidating once they understood the 80/20 rule: most tasks only need a handful of functions. The agent project effectively served as a crash course in practical programming.

How did the 'worst coder' overcome the fear of failing at such an ambitious project?

By embracing a mindset of iterative progress. The coder set tiny goals—like simply fetching the leaderboard data—and celebrated each small win. When the agent crashed or produced incorrect outputs, they reframed it as 'learning what not to do'. They also leaned on online resources shamelessly; copying code was acceptable as long as they understood it afterward. Another technique was to share progress with non-technical friends. Explaining what the agent does in plain language helped clarify the coder's own understanding. Over time, the fear diminished because each attempt proved that failure wasn't catastrophic—it was just a step toward a solution. The final agent wasn't perfect, but it worked, and that was enough to prove that even a complete beginner can build something valuable.

What advice would this coder give to other absolute beginners wanting to build an AI agent?

First, start with a very specific, simple use case. Don't aim to build a general-purpose AI; pick one boring task that you need to solve (like mine—cracking a work leaderboard). Second, use no-code or low-code tools initially. Platforms like Zapier or even simple Python scripts with function calls can get you 80% of the way. Third, expect to spend more time debugging than coding. That's normal. Fourth, document your journey—write down what works and what doesn't; it becomes your personal textbook. Finally, accept imperfection. Your agent might be clunky, break often, and require manual corrections. That's okay. The point is to learn the process of reasoning about automation. The coder's final advice: 'If I can do it, literally anyone can. You just have to ignore the voice that says you're not good enough.'
