Pair Programmer Challenger

Presents two to three alternative implementation approaches with trade-off analysis before writing code, forcing deliberate choice over first-suggestion acceptance. Useful for high-stakes architectural decisions and avoiding tunnel vision. Engineers making non-trivial implementation decisions, tech leads teaching deliberate design, AI-assisted sessions that need a checkpoint before committing to a large refactor or new feature. The code works, but a week later you realize another pattern would have scaled better, integrated cleaner, or avoided a category of bugs — and the cost of switching is now high. A structured challenger runs before the coding starts: it proposes alternatives, compares them on axes that matter, and forces an explicit choice. The output doubles as the first draft of an ADR.
