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

With no annotations, the description carries the full burden. It does disclose one useful behavioral trait — that the response is expanded to include the related customer and the resulting job — but says nothing about read-only nature, permission requirements, or behavior when the request_id does not exist (error vs. empty).

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?

A single short sentence with no wasted words, but it is not front-loaded with an action verb, so it reads as a noun phrase describing output rather than a statement of what the tool does. Concise, yet structurally weak for tool selection.

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 is simple (one required uuid, no nested objects), and the description at least indicates the returned payload includes customer and job. But with no output schema and no annotations, the description should also cover the not-found case and the fact that this is a read operation; those gaps leave it merely adequate.

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?

There is exactly one parameter, request_id, whose name and uuid format are self-documenting in the schema even at 0% description coverage. The description never mentions the parameter, but for a single trivially-named identifier there is little meaning left to add, so this sits at the baseline.

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 phrase "One request with its customer and the job it became" implies fetching a single request by identifier plus joined customer/job data, which does distinguish it from requests_list. However, there is no verb at all ("get", "retrieve", "fetch" never appear), so the agent must infer the operation from the tool name rather than the description.

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?

No guidance on when to use this versus requests_list, requests_pipeline, homeowner_getRequest, or requests_convert, all of which appear in the sibling list. The only implicit signal is the singular "One request", which hints at single-record retrieval, but no alternative or condition is named.

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