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

The annotations already declare readOnlyHint, idempotentHint, openWorldHint, and non-destructive behavior, so the safety profile is largely covered. The description adds a useful behavioral caveat that missing telemetry is treated as unknown rather than zero, but it does not describe auth needs, data freshness, or what lifecycle data is returned.

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 front-loaded and has no filler, but it is too terse for a tool with no output schema and only a single undocumented parameter. The second sentence is useful but cryptic without context.

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?

With no output schema and 0% parameter description coverage, the description should carry more burden. It does not explain what metrics or lifecycle information is returned, what happens when telemetry is missing, or any operational constraints.

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 required 'order' parameter with 0% description coverage, so the description must compensate. It adds the important qualifier that the order must be owned, but it does not explain that the value is a UUID or how to obtain or validate the order identifier.

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 identifies the resource as an owned order and the domain as metrics and lifecycle, which hints at monitoring. However, it uses no clear action verb and does not distinguish the tool from siblings such as emt_orders or emt_terminate beyond the vague phrase 'metrics and lifecycle'.

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?

There is no explicit when-to-use guidance, no exclusions, and no mention of alternatives among the many sibling tools. An agent must infer that this is the monitoring tool rather than an order-listing or termination tool.

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