nexo_memory_observation_stats

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

With no annotations, the description fully carries the burden of behavioral transparency. 'Summarize' implies a read operation, but it does not disclose whether it affects queue state, if it has side effects, or details about the summarized data. The term 'queue status' is vague without further explanation.

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 sentence of 8 words, making it very concise. However, it sacrifices informativeness for brevity, resulting in under-specification. A slightly longer description with key details would be more appropriate.

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?

The tool has one parameter and no output schema, so the description is the primary source of context. It fails to explain what the summary includes, how 'queue status' relates, or what the return value looks like. The description is incomplete for effective use.

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 schema has one parameter 'days' with 0% coverage. The description does not explain the meaning or effect of 'days', only implying a time window through context. Without explicit documentation, the agent cannot infer how to use this parameter correctly.

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 tool summarizes 'passive Memory Observations v2 rows' and 'queue status', specifying the action and resource. However, it does not distinguish this from sibling tools like nexo_memory_observation_list or nexo_memory_observation_process, which could have overlapping functionality.

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. Given the large number of sibling tools (e.g., nexo_memory_observation_list, nexo_memory_observation_process), explicit usage context is missing.

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