LeetCoach

Problem

LeetCode’s Easy / Medium / Hard buckets are too coarse; learners waste time bouncing between problems that aren’t actually easier.

Solution — LeetCoach

A headless CLI coach that uses local Zerotrac numeric difficulty to build real practice ladders.
Given a LeetCode URL (and optional WIP code), Gemini will:

1. Explain the problem — intuition → steps → complexity.
2. Suggest 2–3 strictly easier bridge problems by rating (with guardrails to prevent “accidentally harder” picks).
3. Optionally review your code with a minimal counterexample and tiny patch, then let you choose: solve now or try bridges.

Why Local?

Ratings and statements are files on disk — reproducible, private, and fast.
No scraping or production deployment required.

Gemini Integration

• Non-interactive prompts
• File grounding
• (Optional) MCP shim for ratings lookup

Impact

A reusable pattern for local, data-aware agents that make learning workflows measurably better.
