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

The readOnlyHint=true annotation already establishes the safety profile, and the description is consistent with it. It adds cost information ("Price: free") and the provenance of the ticket, but says nothing about whether this blocks until completion or returns an intermediate state, nor what status values are possible. For a status-checking tool, the async/polling behavior is the key missing trait.

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 compact sentences, front-loaded with the purpose, with the cost note placed last where it does not obstruct. Nothing is redundant, though the terseness borders on under-specification rather than economical writing.

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 must convey what a status response looks like, and it does not—no mention of status values, fields, or completion semantics. For a tool whose entire value is the returned status, this leaves the agent guessing about what it will get back.

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 0%, so the description must carry the load for the single `ticket` parameter. It does partially: identifying the ticket as the one from post_request tells the agent where to obtain the value. It does not describe the ticket's format, lifetime, or validity, leaving a meaningful gap.

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?

"Status of a ticket from post_request" gives a recognizable resource (a ticket) and the operation (fetch its status), and it ties the ticket to the sibling that creates it. It is not quite a clean verb+resource statement—"status" is the returned object rather than the verb—so it falls short of a 5.

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 mention of post_request implies this is the follow-up call after submitting a request, which is useful context. There is no explicit when-not guidance, no statement about polling vs. one-shot checking, and no indication of what to do if the ticket is not yet processed.

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