update_ticket_status

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 only lists valid statuses but does not mention side effects, error handling, permissions, or what happens if the ticket does not exist. This is insufficient 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 a single sentence that is direct and front-loaded with the core action. It wastes no words and includes the key allowed values in parentheses.

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 tool is simple and an output schema exists, but the description still leaves gaps about error behavior, prerequisites, and whether the status list is exhaustive. It is minimally viable but lacks the richer context expected given the absence of annotations.

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 provides zero descriptions for the two parameters, but the description compensates by enumerating the allowed status values, giving meaningful semantic context to the 'status' parameter. The 'ticket_id' is self-explanatory, so the description adds reasonable value beyond the bare schema.

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 tool's purpose with a specific verb 'Update' and identifies the resource as 'status of a ticket'. It also enumerates the allowed statuses (Open, In Progress, Closed, Rejected), which adds precision and distinguishes it from sibling tools like create_ticket.

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 implicitly conveys when to use the tool (when updating a ticket's status), but it does not explicitly state alternatives or conditions. No mention of when not to use it or how it compares to other ticket management tools, leaving usage guidance implied rather than explicit.

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