Most tools have clearly distinct roles: list_sectors/list_sources are catalog reads, show_map renders a sector map, discover_series finds series, fetch_series ingests them, build_panel assembles the panel, and health runs canaries. The only mild overlaps are list_sources vs. show_map (both surface sources for a sector) and discover_series's catalog-seed mode vs. list_sources, but the descriptions differentiate them adequately.

Six of seven tools follow a clean snake_case verb_noun pattern (build_panel, list_sources, show_map, discover_series, fetch_series, list_sectors). The lone outlier is 'health', a bare noun that breaks the pattern but is still unambiguous.

Seven tools is well within the sweet spot and each maps to a distinct stage of the workflow: catalog inspection, discovery, ingestion, panel building, and validation. No tool feels redundant or padded.

The core discover → fetch → build_panel pipeline plus health checks is covered, but there is no way to inspect the local silver layer or list previously built panels, and no update/delete or cleanup operations. Agents can work around this via returned paths/summaries, but the lifecycle surface has notable gaps.
