What problem does it solve? Top-down building produces things that look finished but are not, forcing people to find the gaps themselves through repeated review rounds. This Skill replaces eyeballing with a fixed build order: every job and step is recorded in a store, every advisor test is answered per step, and completeness becomes a queryable check that goes red when anything is missing. ## Core Features & Use Cases - Job and step decomposition: Reads jobs and steps already on record, breaks work into its smallest jobs, and breaks each job into steps one person or one run can finish. - Advisor test answering in the store: Resolves advisor sequences by category from a sequence store and answers every core test (why, asks_to_believe, who_does_it, bad_data_state, stored_and_logged) plus sequence tests as stored rows per step. - Chain walking and self-proving builds: Names the chain to the end recipient, walks back up each link, groups repeating steps into flows, then builds smallest-piece-first and proves completeness with a check that reports red or green. - Use Case: When asked to build a customer onboarding page, the Skill first reads recorded jobs and rulings, answers every advisor test per step in the store, walks the recipient chain, then builds and verifies with the build check before calling anything done. ## Quick Start Ask the assistant to build the onboarding page using the aii-build procedure and show the build check results.
