Scored across 6 tools
The four create_* tools target entirely distinct diagram notations (CLD, ConceptMap, IBIS, Timeline) with no purpose overlap, and decompose and describe_notation are clearly separate meta-operations. describe_notation even helps resolve which notation/tooling applies, reinforcing clarity.
All names use consistent snake_case, and four tools follow the create_noun pattern (create_cld, create_concept_map, create_ibis, create_timeline). The only minor deviation is decompose, which is a bare verb without a noun object, though it remains readable and predictable.
Six tools is well-scoped: one per supported notation plus two infrastructure helpers (describe_notation, decompose). Each earns its place, and splitting the notations into separate create tools is justified by their distinct VGL syntaxes rather than redundancy.
The set covers creation for four notations, plus introspection (describe_notation) and structural editing (decompose), which is solid lifecycle coverage. Minor gaps exist: no generic render/validate path for raw VGL or a notation-listing tool, but agents can work around these via the provided create tools.
