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

Annotations already declare readOnlyHint, openWorldHint, and destructiveHint=false. The description adds valuable return-shape context by specifying that the result includes the full body, headers, and attachment names, which matters because no output schema exists. It does not cover error handling or rate limits, but those are less critical here.

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 tightly written sentences: the first states the return content, the second gives the endpoint. No filler or redundancy; front-loaded with the core purpose.

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, the description compensates by detailing the return fields (full body, headers, attachment names). Combined with annotations covering safety and a fully documented single parameter, an agent has everything needed to invoke it correctly.

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?

Schema description coverage is 100% for the single article_id parameter, including its origin from zammad_list_ticket_articles. The description adds no further parameter syntax or constraints beyond what the schema provides. Baseline 3 applies.

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?

Specifies a concrete verb (GET), a single resource (ticket article), and the scope (one article by id, with full body/headers/attachments). This naturally distinguishes it from the sibling list operation.

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 states what the tool returns but offers no guidance on when to choose it over alternatives like zammad_list_ticket_articles or zammad_get_ticket. It implies retrieval by id but provides no explicit conditions, exclusions, or workflow context.

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