Rigor

Category: Engineering · Sub-category: architecture · Last updated: 2026-05-21

Set the rigor level (0-10) for how critically Claude challenges your decisions. Level 0 = 'just do it bro', level 10 = full devil's advocate questioning everything. Use /rigor <level> to adjust. Great for calibrating AI pushback: low for trivial tasks, high for architecture decisions.

From the source SKILL.md

Set how critically Claude examines your decisions, from zero pushback to maximum scrutiny.
