reply_to_ticket_tool

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

With no annotations, the description carries the transparency burden. It usefully discloses that the correspondence is visible to the requestor, which is a key behavioral trait. However, it does not mention side effects such as notifications, permission requirements, or whether the action is reversible.

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, front-loaded sentence with no filler. Every word adds meaningful information, including the critical visibility qualifier.

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?

This is a simple two-parameter mutation tool with an output schema present. The description is sufficient for understanding the core action and its customer-facing nature. It could be more complete with explicit usage alternatives, but given the low complexity, it is largely complete.

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%, so the parameters ticket_id and message are already described in the schema. The description adds no additional parameter-level detail beyond what the schema provides, so the baseline score of 3 is appropriate.

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 'Reply to a ticket (correspondence visible to requestor)' uses a specific verb and resource, clearly indicating the action. The parenthetical distinguishes it from sibling tools like add_ticket_comment_tool by noting that the reply is visible to the requester.

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 clearly implies this tool is for sending correspondence to the requestor through the parenthetical. However, it does not explicitly state when to avoid it or directly name an alternative like add_ticket_comment_tool for internal notes.

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