init

Lightweight project initialization — optionally scoped to specific files / tables / datasources / domains. Reads the project's SQL (through the persisted table lineage graph, upsert_lineage / query_lineage), human-written docs and the database schema without querying table data, then writes an AGENTS.md project map and per-domain ./knowledge/*.md files holding only statements a source confirms; inferred conclusions are returned as pending questions and written only after the user confirms them. Stops short of the vector-indexed stores (semantic_models / metrics / reference_sql). Single confirmation-free pass.

build-kb

Build the project's vector-indexed knowledge base from files plus database metadata — optionally scoped to specific files / tables / datasources / domains. Scan the in-scope material, classify it into business domains, explore each domain's tables and docs in parallel with explore subagents (the validated-query SQL corpus is enumerated directly, no explore needed), then (after the user confirms a generation manifest — or directly, in the same turn, when the user has waived confirmation) route every artifact to its store via storage-classify, generating semantic_models / metrics / reference_sql (and mining any extra knowledge), and refresh AGENTS.md's KB index. The lightweight /init writes the AGENTS.md project map plus the file-based ./knowledge/*.md; this skill owns the heavy vector-store generation.
