Scored across 5 tools
Each tool occupies a distinct stage of the workflow: brief generation, scanning, repair planning, final verification, and reference listing. The boundaries are mostly clear, though handmade_scan (0-100 score) and handmade_check (PASS/FAIL with ≥85 threshold) both analyze UI code and could be momentarily confused without reading descriptions; handmade_fix_plan also overlaps with scan in producing per-line findings.
All names share a predictable handmade_ prefix with snake_case, which is clean and readable. Minor deviation: list_tells is verb_noun while scan and check are bare verbs and design_brief/fix_plan are noun phrases, so the verb convention isn't uniform.
Five tools is tight and each earns its place in a single end-to-end workflow from brief to verification. No redundant or filler tools are present.
The lifecycle is well covered: generate a design system, scan existing code, repair, and gate on PASS, plus a tells reference. Minor gaps exist in that the design system is written only via a parameter (save_system_to) rather than a dedicated tool, and there's no way to inspect or edit a saved system directly, but agents can work around this.
