Get Knowledge Graph Statistics

get_knowledge_graph_stats
Read-onlyIdempotent

Retrieve statistics from your local knowledge graph, including entity counts, database size, and last activity, to gauge the scope of your accumulated research.

Instructions

Return statistics about the local knowledge graph.

Shows entity counts, database size, and last activity — useful for understanding the breadth of your accumulated research.

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnlyHint and idempotentHint, and the description adds specific output details without contradicting the annotations. It is consistent but does not go beyond what is expected.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loads the action and key outputs, and contains no extraneous information. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With zero parameters, an output schema, and annotations covering safety, the description sufficiently explains the tool's purpose and output. No gaps remain.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has no parameters and 100% coverage, so the description does not need to explain parameters. A baseline of 4 is appropriate as there is no missed opportunity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it returns statistics about the local knowledge graph, listing specific outputs (entity counts, database size, last activity) and distinguishing it from sibling tools that focus on specific domains like diseases or proteins.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It indicates the tool is useful for understanding the breadth of accumulated research, implying its use for high-level overviews. However, it does not explicitly state when not to use it or mention alternatives, though the sibling list provides context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
