Learn Leetcode daily with Claude code mentor

Stewie — Sat, 06 Jun 2026 12:36:57 +0000

This is a submission for the GitHub Finish-Up-A-Thon Challenge

What I Built

After being abandoned for several months, I have come back to build and complete Claude with LeetCode, which is a DSA learning system that automates daily algorithm education with Claude code directly inside GitHub repo.

Every time I submit an accepted solution on Leetcode, the Github workflow fetches my Leetcode account data and commit the problem with the solution to the repo. Claude will then run on a fixed schedule and automatically generates a full structured lecture, covering the DSA topic, brute force through optimal solutions in Python, complexity analysis, and a YouTube video packaged in a GitHub Issue.

This project means a lot to me because it merges two things I care about daily: now not only can I solve Leetcode problem, my solution is automatically analyzed by a powerful AI agent mentor.

The Comeback Story

At first this was only a project to store the Leetcode questions I have solved. The process required manual pushing the problem to the repo and nothing special. Later I have added the automation workflow to fetch data from my Leetcode account, Claude will be prompted like an experienced dsa mentor from Claude and skill.md file to give a thorough analysis on that problem. And at the end of the day, Github Copilot workflow will give a daily summary report to cover my daily progress.

My Experience with GitHub Copilot

I built a DSA Mentor skill that gives Copilot the full context of what a lecture should contain: topic identification, the brute force to optimal approach structure, complexity analysis requirements, and the YouTube search step.
Without Copilot, writing the dsaMentor.js orchestration logic and getting the agent to consistently produce structured markdown output would have taken significantly longer. I then use Copilot cli to help me generate a daily repo status report to cover my daily progress.

How I set up Claude to teach me DSA through Leetcode problems

I just open source a project that allows you to learn DSA through Leetcode with Claude.

Every day you submit a solution on Leetcode. Instead of searching for an explanation from out of nowhere and keeps forgetting it the next day, Claude can now live inside your Github repo and do a thorough analysis for you.

It's called Claude with Leetcode.

You submit a solution on Leetcode. The problem with your accepted solution is then automatically committed to your Github repo. It stores your question and Claude runs the whole analysis of the problem daily. You come back next day and will no longer forget what you have learned. Not a prototype. Not a demo. The actual system.

Here's what makes it different from the others:
→ Claude lives inside your own repo and actually knows data structure algorithm like a true mentor
→ Native Claude plugin support, plug any external tool directly into any agent in your pipeline
→ Built-in memory so every agent remembers context, problems, and history across sessions
→ A pipeline ready to commit your own Leetcode solutions, databases, and knowledge bases
→ Claude skill markdown file that lets Claude to clearly follow instruction as an experienced dsa mentor

Guys, be honest!

Just imagined one day while you are brewing a hot matcha latte in the morning and all of a sudden,.. Ting! You heard the familiar sound of an email notification from your phone. You open and see a big title: "Congratulations! You have been offered a decision to work at Google."

Being able to do that not only takes an insane amount of efforts, but also a detailed and clear roadmap as well.

But have you ever noticed in today's digital world there are a huge amount of information, but most of them are just generic and somewhat unrelated to what you are looking for.

That's why Mirabile is born, an AI-powered career roadmap platform that generates personalized, company-specific learning journeys for engineering roles. You tell it your career goal, your target company, and your timeline — it builds you a complete 18-step roadmap tailored to that exact combination.

Don't just dream, wake up and actually learn!
