mempalace_kg_stats

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

The description implies a read-only operation ('overview'), but no explicit behavioral traits are disclosed. With no annotations, the description carries the burden, but it does not mention side effects, data freshness, or performance characteristics.

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

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

The description is a single, concise sentence that immediately conveys the tool's purpose without extraneous words. It is front-loaded and efficient.

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

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

Given no parameters and no output schema, the description sufficiently outlines the tool's output categories. However, it might benefit from specifying the response format (e.g., JSON) or typical use cases, but overall it is adequate for a simple stats tool.

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

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

There are no parameters, so the input schema is empty. The description adds value by explaining what the tool outputs (entities, triples, facts, relationship types), which goes beyond the schema. Per guidelines, 0 parameters baseline is 4.

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

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

The description explicitly states 'Knowledge graph overview: entities, triples, current vs expired facts, relationship types,' which clearly indicates the tool provides statistics on the knowledge graph. This is a specific verb+resource structure and distinguishes it from sibling tools like mempalace_graph_stats (which may focus on broader graph metrics).

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

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

No guidance is provided on when to use this tool versus alternatives (e.g., mempalace_kg_query or mempalace_status). The description merely states what it does without contextual usage advice, leaving the AI to infer appropriateness.

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