Fillin

Most specialized queries (query_cves, query_frontier, query_markets, query_papers) and marketplace tools are clearly distinct. However, fillin_query, glyph_search, retrieve_auto, encode, and fillin_answer all belong to one retrieval/output-substrate family and could easily be misselected without carefully reading the differences. fillin_health and fillin_stats also overlap in purpose.

The set mixes several conventions: most tools use fillin_* verb_noun names, but encode and retrieve_auto drop the prefix, glyph_search uses a bare noun_verb, and query_cves/query_frontier/query_markets/query_papers use a different query_* prefix. The pattern is readable but clearly inconsistent across the surface.

Seventeen tools is slightly above the comfortable 3-15 range, but the count is justified by the broad scope: retrieval variants, synthesis, glyph rendering, marketplace mint/buy/search, auth/payment helpers, health/stats, and four specialized query domains. Each tool appears to earn its place, though a couple of status/health tools could plausibly be merged.

The server covers retrieval, answer synthesis, glyph substrate, marketplace minting and buying, access/trial/payment flows, and specialized domain queries, so agents have most lifecycle paths covered. Minor gaps exist, such as no explicit balance/account tool or marketplace management beyond buy/mint, but the core workflows are not dead-ended.
