Add Ticket Message

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

Annotations indicate readOnlyHint=false and destructiveHint=true, so the agent already knows this is a mutating operation. However, the description adds no behavioral context beyond 'add', such as irreversibility, side effects, whether the ticket must exist, or what happens on failure. It does not contradict 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?

The description is a single clear sentence with no wasted words. The action and object are front-loaded, making it easy to scan.

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 mutating tool flagged with destructiveHint=true and no output schema, the description is too thin. It lacks usage conditions, side-effect disclosure, return expectations, and any distinction from related ticket tools, leaving the agent to infer important context.

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 50%: id has no description and requestBody is only described as 'The JSON request body.' The tool description implies id refers to a support ticket and body is the message text, adding some meaning, but it does not explicitly map parameters or explain the nested structure.

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?

The description uses a specific verb ('Add') and resource ('a message to a support ticket'), making the core action clear. It is distinguishable from siblings like createTicket, updateTicket, and streamTicketMessages, though it does not explicitly name them.

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?

There is no guidance about when to use this tool versus alternatives such as updateTicket or streamTicketMessages, and no exclusions or preconditions are stated. The sibling list provides context but the description itself gives no routing help.

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