Scored across 8 tools
Most tools have distinct purposes, but architecture_summary and guided_arch_context both provide architectural context, and behavioral_twins and twin_context both involve twins, which could cause confusion. Descriptions help differentiate by emphasizing different outputs and use cases.
All tool names use consistent snake_case and lowercase style. However, the naming pattern mixes verbs (classify, reload, search) and nouns (architecture_summary, behavioral_twins, twin_context), which is slightly inconsistent.
With 8 tools, the server covers a reasonable scope for architecture indexing and context retrieval without being bloated or too sparse. Each tool serves a clear purpose within the workflow.
The tool set adequately covers core operations like getting architecture summaries, searching symbols, classifying prompts, and retrieving twin context. Minor gaps exist, such as lacking tools to modify or create index entries, but the main read and analysis workflows are supported.
