Run a system design interview (HLD, e.g. "design a URL shortener / chat app / feed", or LLD, e.g. "design a parking lot / splitwise classes") calibrated to the candidate's level, from fresher to SDE-2. The agent plays the interviewer, pushes on requirements, scale, trade-offs and bottlenecks, then scores the round. Use when the user wants system design practice, an HLD or LLD round, low-level design, object-oriented design, or "design X" interview prep.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'system-design-mock' ] || [ -L ~/.agents/skills/'system-design-mock' ]; then echo 'A skill folder named system-design-mock already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/nishant-Tiwari24/cracked' "$d" && git -C "$d" checkout --quiet '3fc457cf4fb0ffc214ba97e9ef26d23dbc16b028' -- 'skills/interview/system-design-mock' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/interview/system-design-mock' ~/.agents/skills/'system-design-mock' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'system-design-mock' ~/.claude/skills/'system-design-mock' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
