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

Annotations already declare the destructive mutation profile (readOnlyHint=false, destructiveHint=true), and the description is consistent with that. It adds the valid status names but does not add permissions, reversibility, or side-effect details beyond the annotations.

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 sentences, front-loaded with the action and followed by the valid status names. There is no redundant or wasted text.

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?

For a simple status-update mutation with rich annotations and a fully described schema, the description supplies the key missing detail: allowed status values. It lacks explicit usage guidance, but the core calling information is complete and no output schema exists to explain.

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 100%, so baseline is 3; however, the description adds meaningful semantics by listing the exact valid status names, which the schema’s status property does not express as an enum. It does not explain intentId, but the schema does.

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 verb and resource: "Change a support ticket's status." The enumerated status names further pin down the operation, and no sibling tool performs ticket status changes (ReplyToTicket handles replies instead).

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 purpose implies the tool is used when a ticket status needs changing, but there is no explicit guidance on when to use it versus ReplyToTicket or when not to use it. Usage is inferable rather than stated.

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