Each tool targets a distinct phase of the evidence workflow: source listing, evidence search, document review, assessment validation, and matrix building. The descriptions clarify non-overlapping boundaries, especially around server-derived fields and structural versus semantic validation.

All names use a consistent snake_case verb_noun pattern: list_sources, find_evidence, run_document_review, validate_evidence_assessment, build_evidence_matrix. No mixed conventions or vague verbs appear.

Five tools is well-scoped for a specialized evidence-lab server. Each tool has a clear, non-redundant role in the workflow, and the count avoids both thinness and bloat.

The surface covers the core evidence lifecycle from listing sources through search, review, validation, and matrix building. Minor gaps exist around source ingestion/management and semantic query execution, though the latter is explicitly deferred in the version notes.
