update_ticket_status

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It states that the tool updates a status but does not mention whether this is a mutating operation with side effects, whether permissions are required, or what happens if the ticket ID is invalid. The description adds minimal behavioral context beyond the verb 'update'.

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 extremely concise, consisting of a single clear purpose sentence and two parameter definitions. Every word earns its place, with no redundant or verbose content.

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 core purpose and parameter meanings. However, it lacks details on when to use the tool (usage guidelines) and any behavioral side effects or constraints. The presence of an output schema reduces the need to explain return values, but the missing usage and behavioral context keeps it from being fully 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?

The schema has no descriptions, so the description must compensate. It does: it explains ticket_id as 'Ticket ID' and status as 'New status (Open, In Progress, Closed)', explicitly listing valid status values. This adds meaningful meaning beyond the raw schema properties.

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 the action ('Update the status') and the resource ('a ticket'), and includes parameter definitions for ticket_id and status. It is distinct from sibling tools like create_ticket and list_tickets, making its purpose 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?

The description implies usage when a ticket's status needs to be changed, but it does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions. The sibling tool names hint at context but are not referenced.

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