Most tools target clearly distinct objects: lookups (template_fields, vocabulary, resolve_doi, wikidata_lookup), chain inspection (constellation, constellation_raw, prior_work), and verifiers (verify_chain, verify_quote, validate_rocrate). The main soft spot is the three-way validate_draft / validate_drafts / validate_chain_draft cluster, where the boundary is only clear after reading that one checks authoring input, one checks a directory in bulk, and one checks the wizard artifact. Descriptions do disambiguate these, and constellation vs constellation_raw is explicitly framed as raw-vs-projected.

All names are consistently snake_case, with an implicit verb_noun convention for actions (validate_draft, verify_quote, resolve_doi, list_schemas) and noun names for read-only resource lookups (constellation, vocabulary, template_fields, prior_work). The split between verb-phrased and noun-phrased tools is intentional and readable, though cito_to_wikidata and wikidata_lookup deviate slightly from the dominant pattern.

Fifteen tools sit at the top of the healthy band, and each maps to a distinct phase of a genuinely multi-stage workflow (schema lookup, drafting, validation, publication verification, Wikidata mirroring, RO-Crate checks). No redundant or speculative tool is present; the raw/projected constellation pair and the three validators each serve a non-overlapping need.

Coverage of the authoring-to-verification lifecycle is strong: schema lookup, vocabulary constraints, DOI/QID/quote verification, draft and chain validation, post-publication verification, and downstream Wikidata/RO-Crate artifacts. The notable gap is discovery — constellation and prior_work both require an existing nanopub URI, and there is no tool to find a chain from a DOI, title, or topic, so an agent starting cold has no entry point. PDF text acquisition for verify_quote is also left to the caller.
