Parallel exploration of implementation approaches - implements multiple variants simultaneously and lets tests determine the winner

MANDATORY implementation wrapper. ALWAYS invoke when moving from design→code. Present 3 options: (1) Cookoff - 2-5 parallel agents compete, each creates own plan, pick best, (2) Single subagent, (3) Local. Triggers: "let's build", "implement", "looks good", user picks implementation option, ANY signal to start coding after design. This skill MUST run before writing-plans/executing-plans at design boundaries. For exploring DIFFERENT designs, use omakase-off.
ALWAYS invoke FIRST on ANY "build/create/implement/add feature" request. This skill WRAPS brainstorming - it decides the approach. Present choice BEFORE any brainstorming starts: (1) Brainstorm together step-by-step, OR (2) Omakase - I generate 3-5 best approaches, implement in parallel, tests pick winner. If user picks brainstorming, check if brainstorming skill exists - if yes use it, if no do brainstorming yourself (ask questions, propose options, validate). Also triggers DURING brainstorming on 2+ "not sure"/"don't know" responses. For same design competing implementations, use cookoff.
