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

With no annotations provided, the description carries the full burden of behavioral disclosure. It transparently describes the output contents (date, alerts, categories, sessions) and formatting style (box-drawing characters). However, it does not explicitly state that the tool is read-only or has no side effects, which is a minor gap.

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 extremely concise: two sentences. The first sentence states the primary purpose, and the second lists key output elements and formatting. Every sentence adds value, with no redundancy or filler.

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 simple, parameterless tool, the description is largely complete. It covers the purpose, output contents, and formatting style. However, it does not specify the exact return format (e.g., whether it's a string or interactive element), which is a minor omission given no output schema.

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 input schema has 0 parameters with 100% coverage, so baseline is 3. The description adds no parameter-specific information but instead describes the output structure, which is appropriate given no parameters. No extra semantics are needed beyond the schema.

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 the tool's purpose: generating the NEXO operations center menu with alerts and active sessions. It lists specific output elements (date, due alerts, menu items, active sessions) and uses a clear verb+resource pattern. This distinguishes it from sibling tools like nexo_status or nexo_startup, making its purpose unambiguous.

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 implies usage for retrieving the menu but does not explicitly state when to use it versus alternatives. No exclusions or references to sibling tools are provided. Given the large number of sibling tools (nexo_status, nexo_startup, etc.), explicit guidance would improve selection accuracy.

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