Reference frameworks for coding interviews — the UMPIRE method, a pattern taxonomy (two-pointers, sliding-window, BFS/DFS, backtracking, dynamic-programming, graphs, and more), a Big-O cheatsheet, Python idioms, communication guidance, and anti-patterns. Used by the coding commands (/coding-explain, /practice-coding…

Reference frameworks (RESHADED, the 4S shorthand), capacity estimation cheatsheet, core building blocks (load balancing, caching, queues, sharding, replication, CAP), common tradeoffs, and anti-patterns for system design interview prep. Use when running /mock-sysdesign, /practice-sysdesign, /sysdesign-explain, or…

Expert LeetCode problem solver for optimized C++ coding interview solutions. Use when: the user pastes a LeetCode problem, asks for an optimized algorithm, wants C++ LeetCode code, needs a dry run, asks for line-by-line explanation, wants a hint before the solution, wants brute force to optimized progression, wants…
