reply_to_ticket_tool

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does state a key effect – that the correspondence is visible to the requestor – and mentions the return type. However, it does not disclose other behavioral traits such as whether the reply changes ticket status, sends notifications, requires ownership, or is reversible. For a simple tool this is a reasonable but not complete disclosure.

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 compact and well-structured, with a one-line purpose, an Args section, and a Returns section. Every part earns its place, and the most important information is front-loaded. There is no redundant fluff or repetition of schema details.

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 two-parameter tool with an output schema, the description covers the purpose, both parameters, and the return value. The visibility clarification is essential for selecting it among the many sibling tools. The main gap is a lack of explicit usage guidance, but given the low complexity, the description is sufficiently complete for correct invocation.

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?

The input schema has 0% description coverage, so the description must supply parameter meaning. It does provide brief semantic definitions: 'ticket_id: The ticket ID number' and 'message: The reply message'. While these are accurate and minimal, they add only slightly more than the raw schema types (integer and string) and do not include constraints, format, or examples, so the compensation is adequate but not rich.

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 opens with 'Reply to a ticket' – a specific verb and resource – and adds the parenthetical 'correspondence visible to requestor', which immediately clarifies that this is a customer-facing reply rather than an internal note. This distinguishes it from siblings like add_ticket_comment_tool, making the purpose clear without needing to open other schemas.

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 parenthetical 'correspondence visible to requestor' gives useful context about when this tool is appropriate, implying a contrast with internal comments, but it does not explicitly mention alternatives or when not to use it. No sibling tools are named, and no exclusion conditions are stated, so usage guidance remains implied rather than fully explicit.

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