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

No annotations are provided, so the description carries the burden of explaining behavior. It does reveal the response contents (thread, evidence, playbooks) and the account scope, but it does not explicitly confirm the operation is read-only, describe error handling for invalid references, or mention any access requirements.

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 concise sentence that front-loads the core purpose and immediately lists what the returned ticket includes. Every word contributes value.

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 single-parameter retrieval tool, the description adequately covers the return contents and scope. The lack of an output schema is partly compensated by listing thread, evidence, and playbooks. Minor gaps like existence/error behavior are not critical for this low-complexity tool.

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 coverage is 100%, and the parameter description already provides the format example 'FY-1024'. The tool description adds no new semantic detail beyond 'one ticket of this account', so the baseline 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 clearly states the tool returns one ticket of the account in full, enumerating its contents: thread, evidence, and suggested playbooks. The verb is implicit ('get' in the name) but the resource and scope are specific, and it is distinguishable from sibling list_tickets by emphasizing a single full 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 phrase 'One ticket of this account' clearly indicates this is for retrieving a single ticket's full details, implying contrast with list_tickets. However, it does not explicitly name alternatives or state when not to use the tool, so it falls short of a 5.

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