update_ticket_tool

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

No annotations are provided, so the description must disclose side effects. It states 'Update' implying mutation, but does not mention whether partial updates are supported (though 'All fields are optional' hints at it), permissions required, or error behavior. This is a significant gap for a mutation 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?

The description is two short sentences, front-loaded with the core action and scope. No filler or redundancy. It efficiently communicates the essential information.

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?

The description is minimal but sufficient for the basic operation. However, given the presence of many sibling tools, it lacks any guidance on when to use this versus others. The output schema exists, so return format is covered. The behavior of optional fields (e.g., not updating omitted fields) is implicitly clear but not explicitly stated. Overall, it is adequate but not rich.

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 already describes each parameter (queue, subject, priority) with descriptions comparable to the tool description. The only added value is stating 'All fields are optional', which reinforces the schema's 'required: [ticket_id]'. Since schema coverage is 100%, baseline of 3 is appropriate; no additional semantic depth is provided beyond what the schema states.

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 clearly states 'Update ticket fields' and explicitly lists the fields: subject, priority, queue. This distinguishes it from sibling tools like set_ticket_status or resolve_ticket, which target specific operations. The verb and resource are specific and unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention that it is only for these three fields and that other updates (e.g., status, owner) should go to other tools. The presence of siblings like set_ticket_owner_tool and set_ticket_status_tool makes this distinction important, but the description omits it.

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