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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds useful auth context (ticket or api_key fallback), but says nothing about polling/waiting semantics for an asynchronous human reply, which is the main behavioral risk for this tool.

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 sentences, front-loaded with what is returned and what to supply. No filler, though the parenthetical about api_key is slightly compressed to the point of ambiguity.

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 does state what comes back (status and answers), covering the return-value burden. It is missing only behavioral detail on pending inquiries and ticket provenance for a 3-parameter tool.

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 coverage is only 33%: id and ticket are undocumented in the schema, and the description partially compensates by explaining the ticket-or-api_key alternative path. It still never says what the id refers to or where the ticket comes from, so the compensation is incomplete.

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 (an inquiry's status and answers) and explicitly ties it to its sibling contact_human, which is the tool that creates the inquiry. However, 'Status and answers of an inquiry' is a noun phrase rather than a clear verb, leaving retrieval slightly implicit.

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?

Implies the usage context by referencing contact_human, so an agent can infer this is the follow-up call after creating an inquiry. It does not say when not to use it, whether the inquiry must already exist, or what to do if the status is still pending.

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