Scored across 3 tools
Each tool has a clearly distinct purpose: checking contrast, suggesting accessible alternatives, and parsing color formats. No overlapping functionality exists.
All tool names follow a consistent verb_noun pattern in snake_case (check_contrast, suggest_accessible_color, parse_color). Naming is predictable and uniform.
Three tools is well-scoped for a focused utility server. Each tool earns its place without redundancy or bloat.
The tool surface covers the core workflows of the domain: analyzing contrast, generating accessible alternatives, and parsing colors. No obvious missing operations for the stated purpose.
