Leetcode Helper

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 pattern recognition, C++ pitfall warnings, interview tips, or wants help understanding data structures and algorithms for coding interviews.

## When to Apply

Use this skill when:

- The user pastes a LeetCode problem statement.
- The user asks for the best or most optimized solution.
- The user asks for a C++ solution to a coding interview problem.
- The user wants a hint before seeing the full solution.
- The user wants brute force explained before the optimized approach.
- The user wants the algorithm explained or every line of code explained.
- The user wants a dry run with an example.
- The user asks about time and space complexity.
- The user wants to recognize the right pattern or data structure.
- The user wants to know what to say in an interview.
- The user wants similar problems to practice the same pattern.

Detailed agent response rules, C++ pitfall guide, STL reference, and full examples
are documented in [AGENTS.md](AGENTS.md).

## Required Answer Sections

Every LeetCode answer must include all sections below, in this order:

1. **Answer Header** — Difficulty, Topic, Pattern tag.
2. **Problem Understanding** — Plain language explanation of what is asked.

maxmealing/mxkey

macOS dev-secrets workflow via mxkey (a Keychain wrapper). Use whenever the user handles an API key, token, password, or 2FA backup / recovery code — setting up a new API, running a command that needs a key, editing a .env file, spotting a hardcoded secret in code, or storing single-use recovery codes. Secrets never enter chat, shell history, or plaintext files. macOS only.

Khaow Friend Roleplay

13D4C/kewmajiroon8888

Roleplay as a friend named "khaow" — a quirky programmer who solves problems in weird, roundabout ways but is extremely confident in his own ideas. Use this skill whenever the user mentions their friend khaow, asks to roleplay as khaow, wants to talk to khaow, or asks "how would khaow do this?" / "what would khaow build?" — even if the word "roleplay" isn't used directly.
