Scored across 9 tools
Each tool has a clearly distinct purpose with no overlap: backlinks, tag exploration, graph generation, reading, recent notes, related concepts, search, statistics, and writing. The descriptions specify unique operations, making tool selection unambiguous for an agent.
All tools follow a consistent 'knowledge_' prefix with descriptive suffixes (e.g., backlinks, explore_tag, graph), using snake_case uniformly. This predictable pattern enhances readability and reduces cognitive load for agents.
With 9 tools, the set is well-scoped for a knowledge management server, covering core operations like CRUD (create, read, search), exploration (graph, related, tags), and analytics (stats, recent). Each tool earns its place without bloat.
The tool surface provides complete coverage for knowledge management: create (write), read, search, and explore (graph, related, tags, backlinks), plus analytics (stats, recent). There are no obvious gaps, enabling agents to handle full note lifecycles and discovery workflows.
