memory_stats

Read-only

Check memory database health and scale by viewing total memories, category breakdown, and embedding status. Quickly assess whether embeddings are enabled and monitor storage metrics.

Instructions

Show database statistics (total memories, categories, embedding status).

ACTION GUIDE — when to use:

  • Use when you need to understand the scale or health of the memory database, or check if embeddings are enabled.

TDQS

A4.3/5.0
Behavior3/5

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

Annotations already indicate readOnlyHint=true and destructiveHint=false, so the description adds value by specifying the exact statistics shown. It does not contradict annotations and provides useful behavioral context beyond the annotations alone.

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 concise: two sentences plus a header. It front-loads the action and then provides usage conditions. No wasted words.

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?

Given the tool's simplicity (0 parameters, read-only, output schema exists), the description is complete. It explains the tool's function and when to use it, and the output schema covers return values.

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 zero parameters, so schema description coverage is 100% by default. The description logically adds no parameter information, which is appropriate. Baseline 4 for no parameters.

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 the tool's purpose: 'Show database statistics (total memories, categories, embedding status).' It uses specific verbs and resources, and it distinguishes from siblings like list_memories which returns individual records.

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?

The description includes an explicit usage guide: 'Use when you need to understand the scale or health of the memory database, or check if embeddings are enabled.' This provides clear context, though it does not mention when NOT to use the tool or alternatives.

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