Algo Sensei — DSA & LeetCode Mentor

An algorithms coaching skill that auto-detects your intent and switches between tutoring, progressive hints, code review, mock interviews, and pattern mapping.

EducationBeginner★ 279⑂ 58AI score 8/10Last updated: Oct 22, 2025

What it does

  • Reads your request keywords and routes to one of five modes: Tutor, Hint, Review, Interview, Pattern Mapper.
  • Teaches Socratically — leading questions and staged hints instead of dumping the answer.
  • Reports time complexity (best/average/worst) and auxiliary space, plus trade-offs versus alternative approaches.
  • Helps you recognize patterns (Two Pointers, Sliding Window, DP, Binary Search, Graphs, Backtracking, Monotonic Stack) and suggests similar problems.
  • Answers in your language of choice: Python, JavaScript, Java, C++, Go, TypeScript, Rust and more.

Who it's for

  • Developers and students grinding LeetCode for technical interviews
  • Learners who want to build intuition instead of copying solutions
  • Junior engineers who want their code and complexity sanity-checked

Example uses

  1. "Don't spoil it — give me progressive hints for this problem" → Hint mode reveals the approach step by step.
  2. "Review my two-pointer solution, is it better than O(n²)?" → Review mode gives complexity analysis and refactor ideas.
  3. "Run a mock interview, you be the interviewer" → Interview mode asks follow-ups and scores your explanation.
  4. "What pattern is this problem?" → Pattern Mapper classifies it and lists similar questions.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the SKILL.m folder from the GitHub repo karanb192/algo-sensei into my ~/.claude/skills/algo-sensei/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/karanb192/algo-sensei.git ~/.claude/skills/algo-sensei

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Create the skills folder if needed: mkdir -p ~/.claude/skills
  3. Clone the repo into it: git clone https://github.com/karanb192/algo-sensei.git ~/.claude/skills/algo-sensei
  4. Confirm SKILL.md plus the modes/, templates/, and docs/ folders came along — the per-mode instructions live there.
  5. Restart Claude Code, then try: "use algo sensei to hint me through this LeetCode problem".
  6. For project-only use, clone into your project's .claude/skills directory instead of the home path.
