reverse-prompt-engineer

Reverse-engineer the prompt that most likely produced a given piece of text. Fans out many subagents that each guess a candidate prompt, runs each guess one-shot in a clean room (the executor never sees the target), scores the output against the target, then steers the best candidates over several rounds until the reproduction matches as closely as possible. Trigger when the user says "reverse engineer this prompt", "what prompt produced this", "guess the prompt", "reverse prompt engineer", or invokes /reverse-prompt-engineer. Accepts: the target text (required), and optional tuning — fanout, rounds, keep, threshold.
