The tools are mostly distinct by resource and action, especially the pipeline stages: validate, compile, observe, render, patch, and evaluate. The only mild ambiguity is among get_schema, get_spec_template, and get_spec, though their descriptions do enough to guide selection.

Every tool follows a consistent verb_noun snake_case pattern, such as get_spec, validate_spec, compile_spec, and apply_patch. There are no vague single-word names or mixed conventions.

Thirteen tools is within the ideal scope for a specification-and-rendering server. Each tool maps to a distinct stage in the workflow, from schema exploration and validation to rendering and patch evaluation.

The tool surface covers the full FigureSpec lifecycle: creation from templates, validation, retrieval, compilation, observation, rendering, patching, and visual evaluation. No critical workflow dead ends are evident for the stated domain.
