Gap Analysis
Multi-document engagement scoping against a platform codebase. Turns a folder of client materials (transcripts, spec docs, requirement dumps) into an evidence-backed Epic/Story tree where every story carries a grounded verdict and an atomic-commit effort, then derives a client-facing summary and a prioritized backlog. The trust model is structural, not prose: subagents investigate, but every verdict is re-run by a deterministic gate against a validated, just-freshened local checkout of the platform — a subagent's claim is never written to the tree unverified. The method is generic; everything about a specific platform (repository, integration branch, companion repository, license tiers, capability catalog) is data, resolved from config and the platform's own knowledge. This skill verifies coverage; it does not author requirements or specs — and do that.
