Catechism
Structured clarifying interview to align on intent before non-trivial work. Load when handling /catechism, or whenever a request is vague, multi-interpretable, has unclear scope, would touch many files, involves design tradeoffs, or before exploration/implementation tasks where wrong assumptions would cost real work. Encodes the five dimensions to probe (goal & success criteria, scope & non-goals, constraints, edge cases & failure modes, assumptions to surface), question-crafting rules, batching and pacing, the alignment recap, and the mid-task pause-and-ask pattern.

From the source SKILL.md
A protocol for asking the user the questions only the user can answer, before acting on their behalf. The point is not to be thorough for thoroughness's sake — it's to surface the cheap-to-ask things that are expensive to discover later.
What this skill does
