Get Memory Statistics

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

No annotations are provided, so the description carries full burden. It states this is a 'Get' operation which implies read-only behavior, but doesn't disclose any behavioral traits like whether it requires specific permissions, what format the statistics are returned in, or if there are any rate limits or performance considerations.

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, efficient sentence that states exactly what the tool does without any unnecessary words. It's appropriately sized for a zero-parameter tool and front-loads the essential information.

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?

For a zero-parameter tool with an output schema, the description is minimally complete. It identifies the tool's purpose but doesn't provide context about what specific memory statistics are returned or how this differs from similar statistical tools. The output schema will handle return value documentation, but the description could better situate this tool within the broader memory/cognitive system context.

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?

The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description doesn't need to compensate for any parameter documentation gaps since there are no parameters to document.

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 clearly states the verb 'Get' and the resource 'statistics about the memory system', which is specific and unambiguous. However, it doesn't explicitly differentiate from sibling tools like getThinkingStats or getThinkingProgress, which also retrieve statistical data about cognitive processes.

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?

The description provides no guidance on when to use this tool versus alternatives. With siblings like getThinkingStats and getThinkingProgress that also retrieve statistics, there's no indication of what distinguishes this tool's focus on 'memory system' statistics from other statistical tools in the context.

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