Most tools have clearly distinct targets: catalog lookups (search_nebulae, get_nebula, get_pulsar, cone_search, query_vizier), image rendering (render_cutout vs render_multiwavelength), and analytics. The main softness is in the colour/spectrum cluster, where nebula_color, plot_chromaticity_comparison, plot_cmf_comparison, plot_nebula_spectrum and render_color_swatches all operate on the same observer/template space and could be mis-picked. Position-based search_nebulae versus cone_search is also close, though the bundled-vs-live distinction is stated.

The dominant pattern is a clear snake_case verb_noun (list_surveys, get_nebula, render_cutout, plot_ppdot, search_nebulae, query_vizier). A handful of outliers break the pattern: cone_search is noun_verb, while server_info, cgps_coverage and nebula_color have no verb at all. Readable and predictable overall, but not fully uniform.

20 tools is at the heavy end for a read-only data/visualisation server, and the surface is split across three sub-domains (catalog queries, image rendering, colour science). The six plot_* tools plus three colour-specific tools make the set feel like it grew by accretion rather than being tightly scoped. Each tool is individually defensible, but consolidation of the plotting/colour variants would help.

Coverage across the stated domain is strong: discovery (search_nebulae, cone_search, query_vizier), detail records (get_nebula, get_pulsar), survey discovery and coverage checks, single- and multi-band rendering, population plots, and a full spectral-to-colour pipeline. Minor gaps exist, such as no export/save path for rendered figures and no way to synthesise a custom spectrum beyond the fixed templates. Nothing that would obviously hard-block an agent.
