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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds that the response carries status and result, but says nothing about whether statuses are terminal, whether the call must be repeated until completion, or what happens for an unknown uuid.

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?

Two short fragments, front-loaded with the resource and its return payload; no filler. The trailing REST path is marginal value but not wasteful for agents mapping to the underlying API.

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?

Given no output schema and no dedicated behavioral notes, the description does carry the return contract at a high level ('status and result'), which is the minimum needed. It stops short of the details that matter for a job-polling tool, such as status values or completion semantics.

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?

With a single parameter at 100% schema description coverage, the schema already fully documents uuid including its source. The description's 'by uuid' only echoes that, adding no format or constraint detail 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?

States a specific resource (a single background job) retrieved by uuid and what it returns (status and result), which distinguishes it from the sibling acube_list_jobs. The verb is implicit in the 'by uuid' phrasing and the GET path rather than stated outright.

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?

Retrieval-by-identifier usage is implied clearly enough, and the schema notes the uuid comes from acube_list_jobs. However, the description itself never names that alternative or says when to use this versus listing jobs, nor does it mention polling after a job is created.

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