Invoke the skill with a topic and it generates 2-3 genuinely different approaches, each with pros, cons, effort, and risk. It recommends one option with a concrete hedge condition and waits for your approval before any planning or implementation begins.

Use Rescue Mode, which takes the failed approach and failure evidence as input. It generates 3-5 alternatives from different categories, applies breakthrough frameworks like Collision-Zone Thinking or Inversion, and includes at least one unconventional option.

It spawns 3-4 parallel subagents, each pinned to one constraint such as minimize interface, maximize flexibility, optimize common case, or ports and adapters. A diversity score above 0.4 is required before results are presented with an opinionated recommendation.

No. The skill only produces options, trade-off analysis, and a recommendation. Implementation is blocked by a hard gate until you approve a design, after which the selected approach is handed to the plan skill for structuring.

Use Vision Mode for product-level rethinks rather than implementation questions, triggered by phrases like rethink or reimagine. It restates your real underlying problem, generates approaches that may eliminate the feature entirely, and applies a 10-star experience lens.
