Scored across 3 tools
Each tool has a clearly distinct purpose: decode_plantuml reverses encoding, encode_plantuml prepares code for URLs, and generate_plantuml_diagram creates diagrams with validation. There is no overlap or ambiguity between these functions, making tool selection straightforward for an agent.
All tool names follow a consistent verb_noun pattern with snake_case (decode_plantuml, encode_plantuml, generate_plantuml_diagram). The naming is predictable and readable, adhering to a uniform style throughout the set.
With 3 tools, this server is well-scoped for handling PlantUML encoding, decoding, and diagram generation. Each tool earns its place by covering essential operations without bloat, making the count appropriate for the domain.
The tool set provides complete coverage for core PlantUML workflows: encoding for URLs, decoding back to code, and generating diagrams with validation and error handling. There are no obvious gaps, as these tools support the full lifecycle from code to visual output.
